LOINC Code 41862-4: Viscosity 20 Min post collection (Sem) [Visc]

41862-4 is a LOINC code used to identify Viscosity 20 Min post collection (Sem) [Visc] in laboratory and clinical observation data. You may see this code in lab systems, lab reports, EHR exports, interoperability feeds, or other structured clinical data exchanges. LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Viscosity^20M post collection. It is commonly used with the system or sample type Semen.

  • Status: ACTIVE
  • Order vs observation: Observation

What it does not mean

  • The code identifies the observation or test, not the actual result.

Key facts

Viscosity of Semen--20 minutes post collection
Viscosity^20M post collection
Viscosity is the measurement of resistance of a liquid to flow. Viscosity is a characteristic property of a fluid and typically is a constant for a given liquid at a given temperature.[PMID16830959] Semen may be measured quantitatively using a viscometer rather than the traditional subjective rating method. Determining the seminal viscosity with a quantitative method may be valuable in identifying and treating the subgroup of infertile men with viscid semen. [PMID: 1358311]
