Immunoassay chemistry is a biochemical test that measures the presence or concentration of a molecule in a solution through the use of an antibody. At AIM Labs, these tests come in many different formations and variations, typically involving multiple steps and reagents. All immunoassay testing relies on the ability of an antibody to recognize and bind to a specific molecule that may be present in human serum. Some examples of these tests include:
Common Tests Include:
Anti-Hepatitis A Virus IgM Antibody ( A-HAV IGM) - Antibody tests that detects the first antibody produced by the body when an individual is exposed to Hepatitis A. This test is used to detect early or recent infections and to diagnose the disease in people with symptoms of acute hepatitis.
Anti-Hepatitis B Core IgM Antibody (A-HBC IGM) - The presence of anti-HBc indicates previous or ongoing infection with hepatitis B virus in an undefined time frame. IgM antibody to hepatitis B core antigen (IgM anti-HBc): Positivity indicates recent infection with hepatitis B virus (<6 mos). Its presence indicates acute infection.
Anti-Hepatitis B Surface Antibody (Anti-HBS) - Anti-HBs or HBsAb (Hepatitis B surface antibody) – A “positive” or “reactive” anti-HBs (or HBsAb) test result indicates that a person is protected against the hepatitis B virus. This protection can be the result of receiving the hepatitis B vaccine or successfully recovering from a past hepatitis B infection.
C-Peptide - Substance made in the pancreas that controls the body’s glucose levels. Elevated levels can lead to diabetes.
Ferritin - Protein that contains iron that can show iron deficiency.
Folate - Vitamin that is crucial in red blood cell formation and healthy cell growth and function. Folate deficiency can occur in people who have conditions, such as celiac disease.
Hepatitis C Virus Antibody (HCV) - Antibody test to determine if an individual was exposed to the Hepatitis C virus.
Hepatitis A virus Antibodies IgM and IgG (AHAV) - Antibody test to diagnosis a present or past infection of a person exposed to the Hepatits A Virus.
Hepatitis B Virus Surface Antigen (HBsAG) - Antibody test that is the first serologic marker to appear in a new acute infection of Hepatitis B.
Parathyroid Hormone (PTH) - Secreted by the parathyroid glands and is the most important regulator of blood calcium levels.
ProBNP - Protein that helps evaluate the severity of heart disease including congestive heart failure.
Prostate –specific antigen (PSA) - Protein produced by the prostate gland that when elevated aids in the diagnosis of prostate cancer.
Vitamin B12 - Vitamin that can help diagnose anemia or neuropathy.
Vitamin D 25-Hydroxy - Helps the body absorb calcium and maintain strong bones. Vitamin D is an important indicator of osteoporosis and rickets.
