Article
Research record from Clin Chim Acta, 2026-03-26. PMID 41903863.
Indicators
A semi-essential amino acid (children should obtain it from food) needed in humans for growth and tissue repair, Histidine is important for maintenance of myelin sheaths that protect nerve cells and is metabolized to the neurotransmitter histamine. Histamines play many roles in immunity, gastric secretion, and sexual functions. Histidine is also required for blood cell manufacture and protects tissues against damage caused by radiation and heavy metals. (NCI04)
Indicators
Produced by B-cells, human immunodeficiency virus (HIV) antibodies reacts with HIV antigens. HIV is a virus which affects white blood cells and eventually destroys the body's natural ability to fight infections.
Tests
An HIV test checks a sample of your blood, saliva (spit), or urine (pee) to see whether you are infected with HIV (human immunodeficiency virus). HIV is a virus that destroys certain cells in your immune system . These cells protect your body against diseases from germs , such as bacteria, viruses, and fungi. If you lose too many immune cells, your body will have trouble fighting off infections and other diseases.
Tests
An HIV viral load test measures the amount of HIV in a sample of your blood. HIV stands for human immunodeficiency virus. The test looks for genetic material from the virus in your blood. These tests are called molecular tests or nucleic acid amplification tests (NAAT or NAT). There are several types of NAAT tests. A PCR test is one type of NAAT that may be used to find HIV.
Tests
Quantitative measurement of HIV-1 RNA to stage infection and monitor therapy.
Tests
A homocysteine test measures the amount of homocysteine in a sample of your blood. Homocysteine is an amino acid. Amino acids are molecules that your body uses to make proteins.
Article
Research record from Talanta, 2026-07-27. PMID 42531973.
Article
Research record from HLA, 2026-07-01. PMID 42478549.
Article
Research record from HLA, 2026-10-01. PMID 42813707.
Tests
This test measures the amount of IGF-1 (insulin-like growth factor 1) in your blood. IGF-1 is a hormone , a chemical messenger in your bloodstream that controls the actions of certain cells or organs. IGF-1 manages the effects of growth hormone (GH) in your body. Together, IGF-1 and GH promote normal growth of bones and tissues.
Tests
An immunoglobulins blood test measures the amount of immunoglobulins in your blood. Immunoglobulins are also called antibodies. Antibodies are proteins that your immune system makes to fight germs , such as viruses and bacteria . Your body makes different kinds of antibodies to fight germs in different parts of the body and at different stages of an infection.
