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 T-cell helper (CD4) subset panel. It is commonly used with the system or sample type 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: Order
• Panel type: Panel

What it does not mean

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

Key facts

• T-cell helper (CD4) subset panel - Blood
• T-cell helper (CD4) subset panel
• Absolute CD4 T-cell counts are required to monitor immune status of HIV patients both for prognosis and to decide about initiating treatment. Measuring the absolute CD4 T-cells requires a measure of the absolute lymphocyte count. This can be obtained from the cell counters that produce a CBC with auto diff. It can also be obtained directly from the flow cytometer by using special beads and counting cells with CD45 markers- which identify lymphocytes. CDC recommended the single platform approach (Guidelines for Performing Single-Platform Absolute CD4+ T-Cell Determinations with CD45 Gating for Persons Infected with Human Immunodeficiency Virus MMR.
