Test ID: PYRC    
Pyruvate, Spinal Fluid

Secondary ID A test code used for billing and in test definitions created prior to November 2011

83356

NY State Approved Indicates the status of NY State approval and if the test is orderable for NY State clients.

Conditional

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

Investigating possible disorders of mitochondrial metabolism, when used in conjunction with cerebrospinal fluid lactate collected at the same time to determine the lactate-to-pyruvate ratio

 

Evaluating patients with neurologic dysfunction and normal blood lactate-to-pyruvate ratios

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

The CSF 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 normal blood L:P ratios. Pyruvic acid levels alone have little clinical utility.

Method Name A short description of the method used to perform the test

Spectrophotometry (SP)

Reporting Name A shorter/abbreviated version of the Published Name for a test; an abbreviated test name

Pyruvic Acid, CSF
