LOINC Code 93354-9: Neutrophil CD64 and Monocyte HLA DR panel FC (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 Neutrophil CD64 & Monocyte HLA DR 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
• Method: Flow cytometry

What it does not mean

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

Key facts

• Neutrophil CD64 and Monocyte HLA DR panel - Blood by Flow cytometry (FC)
• Neutrophil CD64 & Monocyte HLA DR panel
• This panel is intended to help distinguish between infectious and non-infectious systemic inflammatory response syndrome (SIRS) by assessing upregulation of CD64 on neutrophils. Expression of HLA-DR on monocytes provides additional prognostic information. Antibiotic treatment before sample collection may affect CD64 expression and will affect interpretation of the assay. Interferon-gamma, G-CSF, or other drugs that affect their levels, cause upregulation of CD64 expression on neutrophils and will affect interpretation of the assay.
