Test Code LA Lactate LAB95

Important Note

Samples collected for whole blood lactate must be run within 30 minutes of collection. Please have the patient present at the lab to be drawn to ensure timely sample processing. 

Test Method


ABL90 Flex Plus



Testing is performed Monday through Sunday.

Typically completed within 30 minutes after the
specimen arrives at the testing site.

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.

Specimen Requirement

Lithium heparin whole blood. 0.5 mL minimum volume. 

Specimens must be run on the instrument within 30 minutes of collection.
