The GGT bood test looks for an enzyme, or protein, called gamma-glutamyl transpeptidase (GGT) in your blood. GGT is found in liver cells. This test helps your doctor look for possible damage to your liver or its ducts. It can also help tell the difference between liver and bone disease if your results from a different blood test called alkaline phosphatase are abnormal. Higher than normal test results could be a sign of liver damage from diseases such as hepatitis, cirrhosis, tumors, or pancreatic cancer. But a higher than normal GGT level does not tell you the specific cause of liver disease or damage.

CPK is creatine phosphokinase, an enzyme in the heart, brain, and skeletal muscle. High CPK can indicate muscle destruction, heart attacks, and central nervous system issues. Long-term exposure to high CPK can load up your kidneys and cause muscle loss and weakness. Sometimes we have no symptoms when CPK is high, but most of the time, we have body aches and soreness. Resistance training can raise CPK, so stop working out for at least five days before the CPK test.

The LDH (lactate dehydrogenase) blood test measures the level of LDH in your blood. LDH is an enzyme in many body organs and tissues, including the heart, liver, muscles, and red blood cells. The LDH test is often used to help diagnose and monitor various medical conditions, such as anemia, heart attack, and liver disease. It may also be ordered to check for tissue damage or monitor treatment effectiveness for specific conditions. Since lactic dehydrogenase is present in many body tissues, its diagnostic usefulness is limited. Tissue specificity may be enhanced by LDH isoenzyme analysis.

This lab test panel includes Total CK (or CPK) and relative percentage of BB (CK-1), MB (CK-2), and MM (CK-3); the percentage of macro CK, if present. The CK or CPK isoenzyme test is used to diagnose myocardial infarction (MI). Three fractions normally may be found, each an isoenzyme: • MM is found in normal serum. • MB is the myocardial fraction associated with MI and occurs in certain other states. MB can be used in the estimation of infarct size.

Renin, also known as angiotensinogenase, is an enzyme that the kidneys produce to regulate aldosterone production. It’s also essential in the renin–angiotensin aldosterone system (RAAS) which maintains your body’s fluid balance and blood pressure. Aldosterone is the primary of several endogenous members of the class of mineralocorticoids in humans. Aldosterone tends to promote sodium and water retention, and lower plasma postasium concentrations.

A hepatic panel is a blood test that helps doctors check for liver injury, infection, or disease. Liver function panels also can check for side effects in the liver from some medicines. This lab test panel measures the blood levels of total protein, albumin, bilirubin, AST, ALT, ALP, and GGT enzymes. High or low levels may mean that liver damage or disease is present.

Lactate dehydrogenase (LD) is an enzyme that is found in almost all of the body's cells, but only a small amount of it is usually detectable in the blood. LD is released from the cells into the bloodstream when cells are damaged or destroyed. Because of this, the LD test can be used as a general marker of injury to cells. Although there is some overlap, each of the five LD isoenzymes tends to be concentrated in specific body tissues. This panel provides 5 types of isoenzymes to detect if LD is coming from the heart, red blood cells, kidneys, lungs, white blood cells, lymph nodes, muscle, or liver.

Alkaline Phosphatase (AP) The isoenzymes test, a diagnostic tool, measures the various forms of alkaline phosphatase (ALP) enzyme that are present in the blood. The body has the enzyme ALP in a variety of tissues, with the liver, bones, kidneys, and intestines having the largest quantities. Isoleucines are the slightly different forms of ALP that various tissues produce.

This panel includes hormones that have been implicated in gynecomastia by several studies. Gynecomastia is a benign enlargement of the male breast resulting from a growth of the glandular tissue of the breast. Since it causes anxiety, psychosocial discomfort and fear of breast cancer, early diagnostic evaluation is important, and patients usually seek medical attention. Causes include hormone imbalance and genetic predisposition.

Women and men living with fibromyalgia do not have characteristic or consistent abnormalities on laboratory testing. However, routine laboratory and imaging studies are important to help rule out diseases with similar manifestations and to assist in diagnosis of certain inflammatory diseases that frequently coexist with fibromyalgia. These are the lab tests commonly checked by physicians treating fibromyalgia patients: CMP, CBC, Urinalysis, TSH, Vitamin D & B-12, Iron/TIBC, Magnesium in RBC, ESR, CPK and Ferritin.

This osteoporosis panel includes:

• Serum total calcium, albumin (to calculate albumin adjusted calcium) and phosphorus as part of a CMP panel to detect conditions associated with hypercalcemia such as primary hyperparathyroidism or hypocalcemia and consequent secondary hyperparathyroidism causing bone loss
• Serum creatinine and estimated glomerular filtration rate (GFR) as part of the CMP panel are useful to detect renal failure which can affect bone health. 
• Serum alkaline phosphatase (ALP) as part of a CMP panel. ALP measurement is useful to detect conditions including Paget's disease, metastatic bone disease and osteomalacia, etc.
• Vitamin D nutrition should be determined by measuring serum 25-hydroxy vitamin D [25(OH)D]. Although there is controversy about the optimum level of 25(OH)D for bone health; while 50 nmol/L is considered acceptable
• Parathyroid Hormone (PTH) measurement would be required if serum calcium is abnormal, to help investigate the cause of the calcium abnormality.
• Ultra-sensitive Estradiol. Low estradiol in men and women has been linked to bone loss.
• Phosphorus. An increased phosphorus with decreased calcium suggests either hypoparathyroidism or renal disease. A decreased phosphorus and an increased calcium suggests hyperparathyroidism or sarcoidosis. When both calcium and phosphorus are decreased diagnostic considerations include malabsorption, vitamin D deficiency and renal tubular acidosis. Increased phosphorus and normal or increased calcium suggests Milk-alkali syndrome or hypervitaminosis D.

These two tests measure antithyroglobulin antibodies and Anti-TPO antibodies that are commonly present in patients with Hashimoto's thyroiditis, Graves disease and other thyroid-related conditions. Antibodies against the protein thyroglobulin can result in the destruction of thyroid cells. TPO antibodies are created when the immune system of a person targets by pure error elements of the thyroid gland or protein, leading to chronic thyroid inflammation, tissue damage, and damage to the thyroid function. Leaving this untreated may cause severe health issues. 

This test panel includes most tests needed to more deeply explore the possibility of hypothyroidism and/or Hashimoto's disease diagnosis. It includes: TSH, Free T3, Free T4, Reverse T3, Thyroglobulin Antibody and Thyroid Peroxidase Antibody (Anti-TPO). If you are taking biotin, please stop it 72 hours before the blood draw since it may interfere with hormone blood tests. A study found that TSH was suppressed in all subjects after food, so fasting may be suggested although it is not reqired by Quest. Free T4 and Free T4 values did not change significantly after eating. NOTE: Reverse T3 is analyzed using a specific technique called liquid chromatography/tandem mass spectrometry (LC/MS-MS). There's a special place in the U.S. where these precise machines needed for LC/MS panels run only on two specific days a week. So, sometimes the clock ticks a bit while we wait for samples to return from their initial collection points. Results may take 7 business days.

Tests included: Color, Appearance, Specific gravity, pH, Protein, Glucose, Occult blood, Ketones, Leukocyte esterase, Nitrite, Bilirubin, Urobilinogen, and Microscopic examination of urine sediment

The adrenal gland produces a hormone known as dehydroepiandrosterone (DHEA). It is also made in the brain. DHEA leads to the production of androgens and estrogens (male and female sex hormones). DHEA levels in the body begin to decrease after age 30. Lower DHEA levels are found in people with hormonal disorders, HIV/AIDS, Alzheimer's disease, heart disease, depression, diabetes, inflammation, immune disorders, and osteoporosis. Corticosteroids, birth control taken by mouth, and agents that treat psychiatric disorders may reduce DHEA levels.

The Rheumatoid Arthritis Factor is often evaluated in patients suspected of having any form of arthritis or destructive articular disease even though positive results can be due to other causes, and negative results do not rule out disease. But, in combination with signs and symptoms, it can play a role in both diagnosis and disease prognosis. It is part of the usual disease criteria of rheumatoid arthritis.

A C-Reactive Protein (CRP) Quantitative test is used to aid in the diagnosis of infections or diseases which cause inflammation. CRP is a protein produced by the liver. Higher than normal concentrations of CRP are often an indicator of infection or inflammation in the body. This test can help determine if an infection is present but not the source of the infection. Conditions that can cause elevated CRP levels include but are not limited to Sepsis, Pelvic Inflammatory Disease, Arthritis, Lupus, Vasculitis, and Inflammatory Bowel Disease.

Cortisol (hydrocortisone) is the most prominent glucocorticosteroid, and it is essential for the maintenance of several body functions. The most important physiological effects of cortisol are that it raises blood sugar levels (enhances gluconeogenesis, or breaks down glucose) and lowers inflammation and the immune system.

T3 or triiodothyronine is the active form of the thyroid hormone. T3 acts as a metabolic throttle for fueling all of the daily cellular functions. Free T3 is the unbound portion of T3 that is biologically active.

This test measures the amount of dihydrotestosterone (DHT) in the blood.  Low DHT has been associated with low libido and high DHT has been linked to acne, hair loss and benign prostatic inflammation in a minority of men.

Estrone (E1) is one of the three estrogens, which also include estriol and estradiol. Estrone is the least abundant of the three and is considered a pro-hormone of estradiol.

Ferritin is a protein that stores iron. Red blood cells need iron to form normally and carry oxygen around your body. Low levels of ferritin lead to iron deficiency anemia, which means you have too few red blood cells. High levels of ferritin can damage your joints, heart, liver, and pancreas.

Lipid Panel: Evaluates the risk for developing atherosclerosis (arterial plaque) and coronary heart disease. This test includes: Total Cholesterol, Triglycerides ,HDL Cholesterol, LDL Cholesterol, Total Cholesterol/HDL Ratio. FASTING REQUIRED.

Includes liver and kidney function, glucose and electrolytes

Both chronically low and high levels of glutathione in the body are indicative of potentially debilitating health problems. Glutathione level is a crucial marker for many diseases, both chronic and acute. Given the importance of this protein to human health; discovering your glutathione levels could be one more way to monitor health levels, immune function, and the potential risk of diseases that have been associated with chronically low or high levels of this essential peptide.

Epstein-Barr (EB) virus is a herpes group virus that is ubiquitous. It leads to infectious mononucleosis and may play a role in the development of Burkitt lymphoma, some nasopharyngeal carcinomas, and a few rare genetic lymphoproliferative disorders. Antibodies to early antigen, IgM and IgG antibodies to viral capsid antigen (VCA), and antibodies to Epstein-Barr nuclear antigen (EBNA) are all part of the EBV test.

ApoB Blood Test has been reported to be a powerful indicator of Coronary Artery Disease (CAD). In some patients with CAD, APO B is elevated even in the presence of normal LDL cholesterol. Instead of non-HDL-C levels, ApoB levels may be used to check how well lipid treatment is working. Non-HDL-C is the total cholesterol concentration minus the amount of HDL. A healthcare practitioner may order both an lipoprotein a (associated with high-density lipoprotein (HDL), the "good" cholesterol) and an apo B to determine an apo B/apo A-I ratio. This ratio is sometimes used as an alternative to a total cholesterol/HDL ratio to evaluate risk for developing CVD.

B12 and folic acid blood testing help doctors diagnose central nervous system disorders, anemia, and malabsorption syndromes. B12 and folic acid also play an important role in energy level, muscle strength and memory. Because B12 and folate are derived solely from dietary intake, such as egg yolks, beef, poultry and fish, many people are deficient in these important vitamins.

THIS IS THE MOST AFFORDABLE TESTOSTERONE TEST IN THE U.S. The most accurate way to measure total testosterone is with liquid chromatography/mass spectrometry. This panel also shows free testosterone percent by equilibrium dialysis and free testosterone calculated from percent free T. This test is more accurate for low and high testosterone blood levels (for men who expect high testosterone blood levels over 1,500 ng/dL, women, and children who usually have low T levels). It has no interferences with supplements or anabolics. Note: Results may take 5-7 business days. For a faster turnaround, choose this test instead: Testosterone, Free, Bioavailable and Total (With Lower & Upper Limit) plus SHBG

The determination of TPO antibody levels is the most sensitive test for detecting autoimmune thyroid disease (eg, Hashimoto's thyroiditis, idiopathic myxedema, and Graves disease) and detectable concentrations of anti-TPO antibodies are observed in most patients with these disorders. The highest TPO antibody levels are observed in patients suffering from Hashimoto thyroiditis. In this disease, the prevalence of TPO antibodies is about 90% of cases, confirming the autoimmune origin of the disease. These autoantibodies also frequently occur (60%–80%) in the course of Graves disease.

NOTE: This test can only be purchased by men with suspect PSA over 4 mg/dL.  Free PSA will not be provided for PSA under 4 ng/mL.

PSA circulates through the body in two ways; bound to other proteins or by itself. Unbound PSA is called free PSA. A free-PSA test will measure the percentage of unbound PSA while a PSA test is used to measure the total of free and bound PSA in the blood. The free PSA is a defective variant of normal PSA that can no longer bind to other proteins and so circulates in the blood in the free form. Although the reason why this is the case is poorly understood - patients with prostate cancer may have lower free PSA levels than those with a benign prostate condition.

This test measures levels of drenocorticotropic hormone (ACTH), which is also called adrenocorticotropin and corticotropin, a hormone made in the anterior pituitary gland that tells the adrenal glands to release cortisol, DHEA, and aldosterone. The ACTH plasma test quantifies the blood's level of ACTH. A patient's blood is drawn for the test and then sent to a lab for examination. The test findings enable the diagnosis of ailments such as Addison's disease, Cushing's syndrome, and adrenal tumors

Quest Diagnostics test code 17911 is for a DNA mutation analysis of Methylenetetrahydrofolate Reductase (MTHFR). The test determines if a patient has one, two, or no copies of either of the two mutations in the MTHFR gene, C677T and A1298C.

Changes in the methylenetetrahydrofolate reductase gene can lead to certain health conditions. One of them is hyperhomocysteinemia (high blood levels of homocysteine), which is a risk factor for cerebrovascular disease, cerebral vein thrombosis, coronary artery disease, myocardial infarction, and venous thrombosis. At least 40 mutations in the MTHFR gene have been identified in people with homocystinuria, a disorder in which the body is unable to process certain amino acids properly.

The PTH test is used to help identify hyperparathyroidism, to find the cause of abnormal calcium levels, or to check the status of chronic kidney disease. PTH controls calcium and phosphorus levels in the blood.

The serum iron test measures the amount of iron in your blood. The total iron-binding capacity (TIBC) test looks at how well the iron moves through your body.

This comprehensive panel includes key vitamins and minerals that affect quality of life and survival. Test included are: Vitamin D, Vitamin B-12, Folate (Folic Acid), Magnesium in Red Blood Cells, and Zinc in Red Blood Cells.

A Magnesium RBC test can provide an earlier indicator of magnesium deficiency that a standard magnesium blood test. When levels are low, the body will pull magnesium from the cells to keep blood levels normal. In this case, a magnesium blood test may show normal levels while a magnesium RBC test will give a more accurate result.

This ultimate lab test panel offers the best savings for men and women to determine their immune health, liver and kidney function, electrolytes, blood sugar, cholesterol, thyroid function, inflammatory markers involved in heart disease, testosterone total and free, urinalysis to determine UTIs and kidney function, estradiol, DHEA-S, vitamins D and B12, and iron/ferritin to determine anemia or increased risk of iron overload.

This panel contains testosterone and its downstream metabolites: Estradiol and DHT. All three hormones are measured using Liquid Chromatography/Mass Spectrometry (LC/MS), the most accurate assay for hormones. No interactions with supplements like biotin are present.

This panel includes blood and urine tests commonly used by physicians to determine kidney dysfunction: Urinalysis, Comprehensive Metabolic Panel (CMP), Cystatin C and eGFR.

Discounted Labs’ basic adrenal insufficiency panel includes cortisol, ACTH, and DHEA as a starting point. Depending on lab test results from this panel, physicians may choose to do an ACTH stimulation test, renin, potassium, and sodium. Imaging studies like a CT scan of the adrenal glands may also be considered to check for adrenal growths. In order to check for Addison's Disease, the auto-immune type of primary adrenal insufficiency, labs should be drawn to check 21-hydroxylase 

D-Dimer is one of the by-products that can be measured after the fibrinolytic system is turned on. Fibrinolytic activation and intravascular thrombosis can be measured by the amount of D-Dimer in the blood. D-Dimer is especially helpful when ruling out venous thromboembolism in people who are at high risk.

This lab test panel includes main blood test makers involved in hair loss in women and men: Complete Blood Count (CBC)- Can detect potential low hemoglobin and infections that can lead to hair loss. Ferritin- Low ferritin, an iron storage protein, has been linked to hair loss and slow down of hair growth. Iron and Total Iron Capacity (TIBC)- Low iron anemia has been linked to hair loss.  Hyperandrogenism: Excessive male hormones (androgens): Total Testosterone (LC/MS), Free Testosterone (Equilibrium Ultrafiltration), DHEA-S, Dihydrotestosterone (DHT)  Hypothyroidism and Hyperthyroidism: Thyroid Stimulation Hormone (TSH), Free Triidothyronine (Free T3)

This panel is popular among men who are on testosterone therapy since it offers substantial savings over ordering each of these tests separately : Complete Blood Count (CBC) ,Comprehensive Metabolic Profile ( includes eGFR ), Estradiol UltraSensitive, Testosterone, Total and Free ( Accurate for all testosterone levels, uncapped), Prolactin, Lipids, and Sex Hormone Binding Globulin (SHBG). FASTING IS REQUIRED.
