LOINC Code 69547-8: Reference nucleotide Molgen Nom (Bld/Tiss)

What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Reference nucleotide. It is commonly used with the system or sample type Bld/Tiss.

When is it used?

• Used in lab systems, EHRs, and clinical data exchange.
• May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
• Status: ACTIVE
• Order vs observation: Observation
• Method: Molgen

What it does not mean

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

Key facts

• Genomic ref allele [ID]
• Reference nucleotide
• Reference values ("normal") examined within the Reference Sequence. This is used in a genotyping test to define the reference and variable nucleotide strings. That is if the sequence variation is an insertion, then Reference Nucleotide will be blank and Variable Nucleotide will contain the inserted nucleotides. In contrast, if the sequence variation is a deletion, then the Reference Nucleotide will contain the deleted nucliotieds, and the Variable Nucleotide will be blank.
