LOINC Code 95155-8: PRRSV ORF5 gene sequence homology to Prevacent Sequencing (Isol)

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 Porcine reproductive and respiratory syndrome virus ORF5 gene sequence homology to Prevacent. It is commonly used with the system or sample type Isolate.

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: Both
• Method: Sequencing

What it does not mean

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

Key facts

• PRRSV ORF5 gene sequence homology to Prevacent in Isolate by Sequencing
• Porcine reproductive and respiratory syndrome virus ORF5 gene sequence homology to Prevacent
• Percent genomic homology between a new isolated PRRS virus strain and a PPRS vaccine strain (e.g. Lelystad, Fostera, IngelvacMLV, IngelvacATP, PrimePac and Prevacent) is based on the number of matching amino acids per total amino acids sequenced in the open reading frame 5 (ORF5) gene. The more homologous the ORF5 gene sequences, the more closely the variants are related. It is thought that sequence homology between isolates and vaccines will predict vaccine efficacy, however this is currently debated since little is known about the immune response to PRRS virus.
