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.

LOINC Code 88544-2: HIV 1 RNA RT mutations detected Sequencing Nom (CSF)

Name: LOINC Code 88544-2: HIV 1 RNA RT mutations detected Sequencing Nom (CSF)
Creator: HealthAssure Clinical Team
Published: 2026-05-21T09:00:16.698Z

88544-2 is a LOINC code used to identify HIV 1 RNA RT mutations detected Sequencing Nom (CSF) 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 gene mutations detected. It is commonly used with the system or sample type CSF.

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 gene mutations detected. It is commonly used with the system or sample type CSF.

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.
