LOINC Code 55451-9: Fibrin+Fibrinogen fragments (PPP)

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 Fibrin+Fibrinogen fragments. It is commonly used with the system or sample type PPP.

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: DEPRECATED
• Order vs observation: Order

What it does not mean

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

Key facts

• Deprecated Fibrin+Fibrinogen fragments in Platelet poor plasma
• Fibrin+Fibrinogen fragments
• Created ONLY for ORDERING in response to request from Canada Health Infoway- a national standardization effort. The dashes in this case mean that the ordering provider does not care what property or scale is used in the observation performed in response to this order. LOINC is still pondering details about how this kind of item should be represented. So the representation might change in the future, but the term will still have the same usage and meaning.
