Colorimetric Enzyme Assay
The over-production or underutilization of lactate usually results in lactic acidosis. Increased lactate levels can occur due to tissue hypoxia, diabetes mellitus, malignancies, glycogen storage disease, metabolic acidosis, and ethanol, methanol or salicylate ingestion.
0.5-2.2 mEq/l (0.5-2.2 mMol/l)
- Blood Lactate
- Lactate Plasma
- LACTIC ACID
STAT requests for this test will be performed on a STAT basis (supervisory staff approval is not required).
It is recommended to draw lactic acid without a tourniquet or immediately after applying the tourniquet. If the tourniquet is applied for an extended time, remove the tourniquet and let the blood circulate two minutes prior to retrying the draw. Collect specimen in gray top tube. Invert tube gently to mix. Place specimen on ice. Centrifuge, aliquot plasma into a plastic vial within 15 minutes of collection and freeze immediately.
No tourniquet. Place on ice immediately and deliver to lab or aliquot within 15 minutes. DO NOT FREEZE WHOLE BLOOD SPECIMEN.
