HIV p24 antigen test
This test measures the level of p24 antigen in blood. Antigen p24 is a protein found in human immunodeficiency virus (HIV). This test is used to evaluate and manage HIV infectio...
HIV-1 Western blot assay
This test measures the amount of antibodies to the HIV virus in blood. This test is used to confirm the diagnosis of a suspected HIV infection[1][2][3][4][5][6][7].
Ham test
This test checks for the presence of red blood cells that break down when acid is added to the blood sample. It is used to detect certain red blood cell disorders. This test is ...
Heavy metal screen, urine
Laboratory panels (a set of tests) are done for many reasons. Panels may be performed for routine health screenings or if a disease or toxicity is suspected. Panels may be used ...
Helicobacter pylori breath test
This test detects the activity of urease by measuring carbon dioxide (CO2) gas in air that is exhaled (breathed out). Urease is an enzyme produced by the bacteria Helicobacter p...
Hematocrit determination
This test measures the volume (amount) of red blood cells (RBC) compared to other components in blood. Test results are reported as a percentage or as a decimal fraction of whol...
Hemochromatosis gene screening test
This test detects a product of a gene mutation called C282Y in blood. This test is used to help evaluate suspected hereditary hemochromatosis (a genetic disorder which affects t...
Hemoglobin A1c measurement
This test measures the amount of a protein called hemoglobin A1C in blood. This test is used to assist in the management of diabetes. Blood collected for this test measures an a...
Hemoglobin determination
This test measures the amount of hemoglobin in blood. It is used to see how much oxygen is being carried by the red blood cells. It is also used in the treatment of red blood ce...
Hemoglobin electrophoresis
This test detects abnormal hemoglobin in blood. Hemoglobin is the part of a red blood cell that transports oxygen and carbon dioxide between the body tissues and the lungs. It i...
Hemolysis panel
Laboratory panels (a set of tests) are done for many reasons. Panels may be performed for routine health screenings or if a disease or toxicity is suspected. Panels may be used ...
Heparin associated thrombocytopenia assay
This test measures heparin antibodies in blood. Antibodies are part of the body's immune system. This test is used when a drug called heparin is suspected of causing thrombocyto...
Heparin induced thrombocytopenia screening test
This is a group of blood tests that help to evaluate a low platelet count that may be caused by the drug called heparin. A low platelet count can lead to problems where the bloo...
Hepatic function panel
Laboratory panels (a set of tests) are done for many reasons. Panels may be performed for routine health screenings or if a disease or toxicity is suspected. Panels may be used ...
Hepatitis A antibody level
This test measures the levels of antibodies to the hepatitis A virus (HAV) in blood. Antibodies are part of the immune system. This test is used to evaluate for a HAV infection ...
Hepatitis A virus antibody measurement
This test measures the levels of antibodies to the hepatitis A virus (HAV) in blood. Antibodies are part of the immune system. This test is used to evaluate for a HAV infection ...
Hepatitis B surface antibody measurement
This test is detects hepatitis B antibodies in blood. It is used to evaluate for an infection with the hepatitis B virus[1][2][3][4]. This test may also confirm immunity to the ...
Hepatitis Be antibody measurement
This test measures the amount of antibodies to hepatitis Be antigen in blood[1]. It is used to evaluate a hepatitis B infection[2].
Hepatitis C nucleic acid assay, Qualitative
This test measures nucleic acid (building blocks of genes) of the hepatitis C virus in blood. This test detects if there is an active hepatitis C infection. It may be done after...
Hepatitis C nucleic acid assay, Quantitative
This test measures the amount of nucleic acid (building blocks of genes) of the hepatitis C virus in blood. This test is used to detect this virus and determine the viral load (...
