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 Phosphofructokinase.F subunit/Phosphofructokinase.total. It is commonly used with the system or sample type Platelets.

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: Observation

What it does not mean

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

Key facts

  • Phosphofructokinase F subunit/Phosphofructokinase.total in Platelets
  • Phosphofructokinase.F subunit/Phosphofructokinase.total
  • NFR is probably not the right property. These are probably not being tested as fractions of total phosphofructokinase.
