Tests
An alkaline phosphatase (ALP) test measures the amount of ALP in your blood. ALP is an enzyme, a protein that speeds up certain chemical reactions in your body. ALP is found in all your body tissues, but higher amounts can be found in your liver, bile ducts, and bones. Each part of your body makes a different type of ALP.

Glossary Term
Mutually exclusive alternative forms of the same gene occupying the same locus on homologous chromosomes, differing in nucleotide sequence and governing the same biochemical and developmental process.
Tests
An allergy blood test measures the amount of allergy-causing antibodies called immunoglobulin E (IgE). Antibodies are proteins that your immune system makes to fight foreign substances, such as viruses and bacteria . But your immune system may also make them in response to allergens. These are harmless substances, such as pollen and peanuts, that may cause an allergic reaction in some people.
Tests
An AFP tumor marker test is a blood test that measures the level of AFP (alpha-fetoprotein) in a sample of your blood. AFP is a protein that the liver makes when its cells are growing and dividing to make new cells. AFP levels are normally high in a fetus, but after birth, they drop very low. Healthy children and adults who aren’t pregnant have very little AFP in their blood.
Tests
Alpha-1 antitrypsin (AAT) testing uses a sample of blood or a cheek swab to diagnose a condition called alpha-1 antitrypsin deficiency (AAT deficiency). This condition is sometimes known as "alpha-." or AATD. If you have AAT deficiency, your body doesn't make enough AAT.
Indicators
Alpha-1-acid glycoprotein 1 (201 aa, ~24 kDa) is encoded by the human ORM1 gene. This protein may play a role in immunosuppression and small molecule transport.
Indicators
Alpha-2-macroglobulin (1474 aa, ~163 kDa) is encoded by the human A2M gene. This protein has activity as a protease inhibitor.
Indicators
Alpha-fetoprotein (609 aa, ~69 kDa) is encoded by the human AFP gene. This protein plays a role in the binding to copper, nickel, bilirubin and fatty acids in the fetal circulation.
Tests
An AFP test is a blood test that measures the level of alpha-fetoprotein (AFP) in your blood when you are pregnant. The test checks your baby's risk of having certain birth defects and genetic problems , but it does not diagnose any health conditions. The test is usually done between 15 and 20 weeks of pregnancy .
Tests
An ALT test measures the amount of ALT in your blood. This test is commonly used to help diagnose liver damage or disease .
