Immunoglobulin A (IgA) is a crucial antibody in the immune system, predominantly found in mucous membranes of the respiratory and gastrointestinal tracts. It helps protect against infections by neutralizing pathogens before they can cause harm. Testing IgA levels can provide insights into immune health, indicating potential issues such as chronic infections, autoimmune diseases, or immunodeficiency disorders. Elevated or decreased IgA levels can signal various health conditions, making this test valuable for diagnosing and managing immune-related issues. For those experiencing frequent infections or gastrointestinal issues, an IgA test can be an essential diagnostic tool.

The Urinalysis test panel screens for a variety of conditions including urinary tract infections ( UTI ), urinary bladder disease, kidney disease and diabetes. Tests included: Color, Appearance, Specific gravity, pH, Protein, Glucose, Occult blood, Ketones, Leukocyte esterase, Nitrite, Bilirubin, Urobilinogen, and Microscopic examination of urine sediment

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.

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.

A complete blood count CBC with differential test panel measures several components of your blood including:Red blood cells, which carry oxygen, White blood cells, which fight infection, Hemoglobin, the oxygen-carrying protein in red blood cells, Hematocrit, the proportion of red blood cells to the fluid component in your blood (which correlated with blood thickness), and Platelets, which help with blood clotting. This is also called Complete Blood Count (CBC) with Differential and Platelets Blood Test

Includes liver and kidney function, glucose and electrolytes

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.

Iodine, Serum/Plasma - Iodine is an essential element that is required for thyroid hormone production. The measurement of iodine serves as an index of adequate dietary intake and iodine overload, particularly from iodine-containing drugs.

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.

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.
