What does this LOINC code represent?

This LOINC code identifies a lab observation, measurement, question, or clinical concept in a standardized format.

Is this enough to understand my test result?

No. The code identifies the test or observation, but the interpretation depends on the actual result, reference range, and clinical context.

Order vs observation: Observation

What it does not mean

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

Key facts

Allelic frequency in Population

Allelic frequency

The allelic frequency is the relative frequency (or fraction) of the given allele reported at the locus of interest in a given population. It is usually expressed as a number from 0 to 1. (https//www.sciencedirect.com/topics/neuroscience/allele-frequency) Allelic frequency is usually reported as a decimal fraction for both Sample Variant Allelic Frequency and Population Allelic Frequency, although it is occasionally reported as a percent. Special care/caution should be taken when reporting and converting to a decimal fraction.
