LOINC Code 78001-5: CMV pp65 Ag/100000 PMN cells IF (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 Cytomegalovirus pp65 Ag/100000 PMN cells. 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: Both
• Method: IF

What it does not mean

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

Key facts

• Cytomegalovirus pp65 Ag/100000 PMN cells in Blood by Immunofluorescence
• Cytomegalovirus pp65 Ag/100000 PMN cells
• Human Cytomegalovirus (HCMV) isolation from leukocytes of peripheral blood (viremia) and/or pp65 antigenemia are evidence for active systemic infection. The number of pp65-positive PMN (polymorphonuclear cells) per 10*5 PMN are reported. A single stained cell indicates positive antigenemia. This term was created for, but not limited in use to, the submitter's CINAkit ARGENE Rapid Antigenemia test kit, which uses an indirect immunofluorescence method to detect internal matrix phosphoprotein (protein kinase) pp65 of HCMV.
