Tests
The determination of the remnant lipoprotein present in a sample.
Indicators
Renin (406 aa, ~45 kDa) is encoded by the human REN gene. This protein plays a role in activation of angiotensin.
Tests
The determination of the amount of renin present in a sample.
Glossary Term
Complementary precision measures: repeatability is variation under the same conditions (same operator, equipment, short interval); reproducibility is variation across conditions — different days, operators, lots, or laboratories.
Tests
The determination of the amount of replication competent lentivirus RNA present in a sample.
Glossary Term
The ability to yield similar results given a set of constraints.
Article
Plan respiratory testing capacity before the season starts: demand baselines, single-plex versus syndromic menus, inventory buffers, staffing floors, and turnaround tiers.

Research record from Eye (Lond), 2026-03-27. PMID 41896456.
Tests
The determination of the ratio of reticulocytes to total cells present in a sample. The measurement may be expressed as a ratio or percentage.
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.
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.
