LOINC Code 81652-0: HIV 2 RNA NAA+probe [Log #/Vol]

81652-0 is a LOINC code used to identify HIV 2 RNA NAA+probe [Log #/Vol] 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 2 RNA. It is commonly used with the system or sample type Ser/Plas.

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 2 RNA. It is commonly used with the system or sample type Ser/Plas.

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: Probe.amp.tar

What it does not mean

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

Key facts

  • HIV 2 RNA [Log #/volume] (viral load) in Serum or Plasma by NAA with probe detection
  • HIV 2 RNA
  • This assay quantifies Human Immunodeficiency Virus Type 2 (HIV-2) RNA isolated from human plasma through the use of Real-Time PCR. The HIV-2 real-time PCR assay includes viral lysis and nucleic acid extraction using Nuclisens EasyMag, reverse transcription using Bio-Rad iScript cDNA synthesis, and Real-Time PCR on the resulting cDNA.
