Test Code LA Lactate LAB95
Performing Laboratory
UnityPoint The Finley Hospital
Test Method
Amperometry
ABL90 Flex Plus
Performance
Testing is performed Monday through Sunday.
Typically completed within 30 minutes after the
specimen arrives at the testing site.
Specimen Requirement
Lithium heparin whole blood. 0.5 mL minimum volume.
Specimens must be run on the instrument within 30 minutes of collection.
Useful For
Diagnosing and monitoring patients with lactic acidosis.
Elevated levels of lactate are mainly found in conditions of
hypoxia such as shock, hypovolemia, and left ventricular failure;
in conditions associated with diseases such as diabetes mellitus,
neoplasia, and liver disease; and in conditions associated with
drugs or toxins such as ethanol, methanol, or salicylate. Lactic
acid measurements are being used as a screening tool in evaluating
for severe sepsis. In severe sepsis circulatory abnormalities
(intravascular volume depletion, peripheral vasodilatation,
myocardial depression and increased metabolism) lead to an
imbalance between systemic oxygen delivery and oxygen demand,
resulting in global tissue hypoxia or shock.
