Glossary Term
A WHO procedure that time-limits the listing of diagnostics (and other health products) for use in public-health emergencies when full prequalification is not yet available.
Glossary Term
A 50-150bp DNA sequence that increases the rate of transcription of coding sequences. It may be located at various distances and in either orientation upstream from, downstream from or within a structural gene. When bound by a specific transcription factor it increases the levels of expression of the gene, but is not sufficient alone to cause expression. Distinguished from a promoter, that is alone sufficient to cause expression of the gene when bound.
Indicators
The most potent form of the naturally occurring steroid sex hormone in humans, produced by ovary, placenta, testis, and in small amount by adrenal cortex. Estradiol binds to a specific intracellular estrogen receptor located in female organs, breasts, hypothalamus and pituitary. The receptor-ligand complex promotes gene expression necessary for the maintenance of fertility and secondary sexual characteristics in females. In addition, estradiol exhibits mild anabolic and metabolic properties, and increases blood coagulability. Estradiol, the principal intracellular human estrogen, is substantially more active at the cellular level than its metabolites, estrone and estriol.
Article
Research record from J Med Virol, 2026-04-01. PMID 41910370.
Tests
The determination of the amount of RNA encoded by a specific exon in a biological sample.
Tests
The intracellular iron-storage protein measurable in serum; the most useful single test of iron stores.
Tests
This test measures the level of follicle-stimulating hormone (FSH) in a sample of your blood. A hormone is a chemical messenger in your bloodstream that controls the actions of certain cells or organs. FSH plays an important role in sexual development in children and fertility in adults.
Tests
The determination of the amount of free prostate specific antigen in a biological sample.
Tests
The determination of the ratio of free prostate specific antigen as compared to the total prostate specific antigen present in a sample. The measurement may be expressed as a ratio or percentage.
Indicators
Galectin-3 (250 aa, ~26 kDa) is encoded by the human LGALS3 gene. This protein plays a role in both antibody-mediated immunity and carbohydrate binding.
Indicators
Gamma-enolase (434 aa, ~47 kDa) is encoded by the human ENO2 gene. This protein is involved in glycolysis, neurotrophy and neuroprotection.
Tests
Laboratory test involving interaction of antigens with specific antibodies.
