What is Lactate?
A healthcare practitioner suggests a lactate test when patients experience sepsis, shock, severe congestive heart failure, etc. The symptoms include rapid breathing, nausea, and sweating, suggesting a lack of oxygen. High blood lactate may indicate the lack of oxygen or excess production/insufficient clearing of lactate from the blood.
Excess lactate in the blood can lead to lactic acidosis, and the person is said to have hyperlactatemia. Sample can be collected from both venous and arterial blood for lactate level measurement. Prior to the lactate test, doctors advise refraining from exercise or eating or drinking anything (other than water) for 8 to 10 hours.
