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 Lactate dehydrogenase panel. It is commonly used with the system or sample type Ser/Plas.

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

• Lactate dehydrogenase panel - Serum or Plasma
• Lactate dehydrogenase panel
• This panel contains the results for lactate dehydrogenase (LD) and LD isoenzymes in serum or plasma. For reporting LD levels in serum, the recommendation is to use one of the method-specific codes because there is a 3-fold difference in normal range between L>P and P>L methods.The methodless LD term is kept in the panel for labs that may still be using it so they will be able to map to this panel.
