Article
Plan respiratory testing capacity before the season starts: demand baselines, single-plex versus syndromic menus, inventory buffers, staffing floors, and turnaround tiers.
Tests
The determination of the amount of respiratory syncytial virus in a sample.
Tests
The determination of the amount of respiratory syncytial virus type A in a biological sample.
Article
Research record from Eye (Lond), 2026-03-27. PMID 41896456.
Indicators
The fat soluble vitamin retinol. Vitamin A binds to and activates retinoid receptors (RARs), thereby inducing cell differentiation and apoptosis of some cancer cell types and inhibiting carcinogenesis. Vitamin A plays an essential role in many physiologic processes, including proper functioning of the retina, growth and differentiation of target tissues, proper functioning of the reproductive organs, and modulation of immune function.
Tests
The determination of the amount of retinol binding protein 2 in a sample.
Glossary Term
A study in which participants with known outcomes are assessed based on data collected before the study.
Glossary Term
An RNA-dependent DNA polymerase that is involved in the replication of retroviruses an in the maintenance of telomeres.
Glossary Term
The action of copying RNA into DNA by reverse transcriptase.
Indicators
Antibodies in the serum of individuals with rheumatoid arthritis that react with antigenic determinants or immunoglobulins that enhance agglutination of suspended particles coated with pooled human gamma-globulin. Rheumatoid factors also occur in other autoimmune and certain infectious diseases.
Tests
The determination of the rheumatoid factor antibody IgG present in a sample.
Indicators
An essential human nutrient that is a heat-stable and water-soluble flavin belonging to the vitamin B family. Riboflavin is a precursor of the coenzymes flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD). These coenzymes are of vital importance in normal tissue respiration, pyridoxine activation, tryptophan to niacin conversion, fat, carbohydrate, and protein metabolism, and glutathione reductase mediated detoxification. Riboflavin may also be involved in maintaining erythrocyte integrity. This vitamin is essential for healthy skin, nails, and hair.
