Useful For Suggests clinical disorders or settings where the test may be helpful

Screening for possible disorders of mitochondrial metabolism, when used in conjunction with blood lactate collected at the same time, to determine the lactate-to-pyruvate ratio

Genetics Test Information Provides information that may help with selection of the correct genetic test or proper submission of the test request

The lactate:pyruvate (L:P) ratio is considered a helpful (not diagnostic) tool in the evaluation of patients with possible disorders of mitochondrial metabolism, especially in patients with neurologic dysfunction and either elevated or normal blood lactate levels. Pyruvic acid levels alone have little clinical utility.

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.
