Lactate

Lactate serves as indicator for the oxygen status in cellular tissues; high levels occur in anoxia due to shock, congestive heart failure, intoxication and thiamine deficiency.

Each laboratory should check if the reference ranges are transferable to its own patient population and determine own reference ranges if necessary. For diagnostic purposes, the results should always be assessed with the patient’s medical history, clinical examinations and other findings.
