4128: Lactic Acid Plasma Print View
Lactic Acid, Plasma S  4 - 16  mg/dL 

PRIMARY
1 Plasma Fluoridated/Oxalat 1 (0.5) mL   Refrigerated - 7 Day(s)/Frozen - 3 Month(s)  
ALTERNATE

Lactic acid is the end product of the anaerobic metabolism of glucose. The blood lactic acid concentration is affected by its production in muscle cells and erythrocytes and its rate of metabolism in the liver. During exercise, blood lactate can increase up to ten times of normal levels.

The collected blood should be well mixed and separated from the cells
within 3 hours. Freeze plasma and ship frozen.

The assay manufacturer, Roche, notes that N-acetylcysteine, when
administered in high concentrations (such as for treatment of
acetaminophen overdose), can interfere with their assay for Lactate
(Lactic Acid), leading to falsely low results.

Notes
Ascorbic acid levels greater than 30 mg/dL interfere with results. In very rare cases, gammopathy, particular type IgM, may cause unreliable results. Patient Preparation: Sample should be collected without the use of a torniquet; avoid hand-clenching. If a tourniquet has been used, it should be released for one minute prior to drawing blood. Collected blood should be cooled on ice immediately and separated from the cells within 3 hours. Reject Criteria: Gross hemolysis; Specimens with visible icterus
