LOINC Code 81430-1: LDH Lactate to pyruvate reaction (Perit dial fld) [Catalytic activity/Vol]

81430-1 is a LOINC code used to identify LDH Lactate to pyruvate reaction (Perit dial fld) [Catalytic activity/Vol] in laboratory and clinical observation data. You may see this code in lab systems, lab reports, EHR exports, interoperability feeds, or other structured clinical data exchanges. LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Lactate dehydrogenase. It is commonly used with the system or sample type Dial fld prt.

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. It is commonly used with the system or sample type Dial fld prt.

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: Reaction: lactate to pyruvate

What it does not mean

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

Key facts

Lactate dehydrogenase [Enzymatic activity/volume] in Peritoneal dialysis fluid by Lactate to pyruvate reaction
Lactate dehydrogenase
Elevated lactate dehydrogenase is a marker for various types of tissue injury. In patients undergoing peritoneal dialysis, elevated LDH in the dialysate may be a sign of peritonitis, and failure of dialysate LDH levels to normalize during treatment of peritonitis may be associated with incomplete recovery and a higher rate of complications compared to patients whose LDH levels decrease back to normal levels.
