A blood pregnancy test is a medical test used to determine if a woman is pregnant by detecting the presence of the hormone hCG in her blood. Shortly after the fertilized egg implants into the uterine lining, the developing placenta produces the hormone known as hCG. This test is the Quantitative hCG test (also known as a beta hCG test) and measures the specific amount of hCG present in the blood. It can help determine how far along a pregnancy is, monitor the progress of the pregnancy, and detect potential issues like an ectopic pregnancy or a miscarriage.

Blood pregnancy tests are more sensitive than over-the-counter urine pregnancy tests and can detect pregnancy earlier – as soon as 6 to 8 days after ovulation.

Elevated levels of homocysteine in the blood, known as hyperhomocysteinemia, have been linked to an increased risk of cardiovascular disease, including heart attack and stroke. High homocysteine levels may also be associated with an increased risk of certain other health conditions, such as osteoporosis and pregnancy complications.

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.

The cystatin C test (which also includes estimated creatinine clearance eGFR) can be done along with the creatinine or creatinine clearance test in cases where those tests aren’t appropriate, such as patients taking creatine supplements for bodybuilding. These supplements can increase creatinine and decrease creatinine clearance, which can alarm doctors who fear kidney dysfunction.  This creatinine increase is not clinically relevant, but running a Cystatin C test can give physicians reassurance and allow the patient to keep taking that effective bodybuilding supplement. 

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.

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. 

 A prolactin blood test is used by doctors to evaluate sexual dysfunction or very low testosterone blood levels of unknown causes in both men and women.

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 erythrocyte sedimentation rate (ESR or sed rate) is the rate at which red blood cells sediment in a period of one hour. It is a common hematology test and is a non-specific measure of inflammation. To perform the test, anticoagulated blood is traditionally placed in an upright tube, known as a Westergren tube, and the rate at which the red blood cells fall is measured and reported in mm at the end of one hour. Elevated levels of ESR are usually found in people who have different types of diseases, such as autoimmune disease, anemia, kidney disease, cancer, and other health complications.

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.

This test measures thyroglobulin antibodies commonly present in patients with Hashimoto's thyroiditis. Antibodies against the protein thyroglobulin can result in the destruction of thyroid cells. This destruction can lead to hypothyroidism. NOTE: Dietary supplements containing biotin may interfere in assays and may skew results to be either falsely high or falsely low. For patients receiving the recommended daily doses of biotin, draw samples at least 8 hours following the last biotin supplementation. For patients on mega doses of biotin supplements, draw samples at least 72 hours following the last biotin supplementation.

The thyroid stimulating hormone (TSH) is produced and secreted by the pituitary gland and stimulates the thyroid to produce T3 and T4. When TSH is elevated, low thyroid function may be indicated. If TSH is low it is indicative of high thyroid function. 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.

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.

This panel includes comprehensive testing of the thyroid stimulating hormone (TSH) in addition to free thyroxine (T4) and free triiodothyronine (T3).

The thyroid gland produces and secretes T4, otherwise known as thyroxine. Proteins bind to T4 and carry it throughout the bloodstream. Once in the tissues, T4 is released from the proteins and is now free to convert into the more active form called T3. For this reason, many doctors believe that measuring free T4 is a more sensitive test for thyroid hormone production.

Blood typing is used to determine an individual's blood group, to establish whether a person is blood group A, B, AB, or O and whether he or she is Rh positive or Rh negative.

Thyroxine-binding globulin (TBG) is a globulin that binds thyroid hormones in circulation. It is one of three transport proteins (along with transthyretin and serum albumin) responsible for carrying the thyroid hormones thyroxine (T4) and triiodothyronine (T3) in the bloodstream. Of these three proteins, TBG has the highest affinity for T4 and T3 but is present in the lowest concentration. Despite its low concentration, TBG carries the majority of T4 in the blood plasma.

This is the most accurate progesterone test that has no potential interactions and can detect very low levels in men and women.  Since it is performed with liquid chromatography and mass spectrometry, results are available after 5 to 7 business days.

The Anti-Mullerian Hormone ( AMH ) Test is used to assess ovarian function and menopausal status; in the evaluation of polycystic ovary syndrome (PCOS) or to evaluate the effectiveness of ovarian cancer treatment.

Estrogen is the primary female sex hormone as well as a medication. It is responsible for the development and regulation of the female reproductive system and secondary sex characteristics. There are three major endogenous estrogens in women and men: estrone, estradiol, and estriol. This test does not specify each of these estrogens.

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.

 Progesterone is a female hormone important for the regulation of ovulation and menstruation. It is also present in men in smaller concentrations. Progesterone is a steroid hormone that plays numerous roles within the human body. It is crucial to the production of sex hormones and corticosteroids, as well as playing a role as a neuro-steroid (brain function).

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.
