LOINC Code 90901-0: HIV 1 RNA reverse transcriptase and protease and integrase gene sequence Nom (S/P/Bld)

90901-0 is a LOINC code used to identify HIV 1 RNA reverse transcriptase and protease and integrase gene sequence Nom (S/P/Bld) 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 HIV 1 RNA reverse transcriptase & protease & integrase gene. It is commonly used with the system or sample type Ser/Plas/Bld.

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 HIV 1 RNA reverse transcriptase & protease & integrase gene. It is commonly used with the system or sample type Ser/Plas/Bld.

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
