TEST ID LAPYP Lactate Pyruvate Panel, Plasma

Reporting Name

Lactate Pyruvate Panel, P

Specimen Type

Plasma


Ordering Guidance


This test does not measure D-lactate, an uncommon, often undiagnosed cause of lactic acidosis. If D-lactate testing is needed, order DLAU / D-Lactate, Urine (preferred) or DLAC / D-Lactate, Plasma.

 

Analytes from this test are included in test MMPP / Mitochondrial Metabolites, Plasma. If ordered together, this test may be canceled.
