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 Paroxysmal nocturnal hemoglobinuria GPI-Linked WBC & RBC Ag 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

• PNH GPI-Linked WBC and RBC Ag Panel - Blood
• Paroxysmal nocturnal hemoglobinuria GPI-Linked WBC & RBC Ag Panel
• The tests in this panel detect glycosylphosphatidylinositol (GPI)-linked proteins including CD14 for monocytes, CD16 and 24 for granulocytes, and CD59 for erythrocytes. In addition, fluorescent aerolysin (FLAER) which selectively binds to GPI anchor proteins, is also used to detect the presence or absence of those anchors. Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired hematologic disorder of erythroid, granulocytic, and megakaryocytic cell lines. The abnormal cells in PNH are missing the GPI-linked proteins due to mutations in the phosphatidylinositol glycan A gene (PIGA).
