Purpose of the Test

A lactate level test may be ordered when someone has signs and symptoms of a condition that may affect lactate production or clearance. It is often ordered in emergency settings when a person is critically ill.

When this test is required

A lactate level test is often ordered in emergency situations, such as when someone has sepsis or is in shock. It may also be ordered when someone has a suspected heart attack or heart failure, or when someone has a lung or liver disease.

What the Test Detects

The test measures the amount of lactate, a waste product produced by cells when they have insufficient oxygen to produce energy via aerobic respiration. The lactate level is a measure of how much anaerobic metabolism is taking place in the body.

Preparation for the Test

There is no specific preparation needed for a lactate level test.

Sample Requirements

A blood sample is collected from a vein in the arm, or sometimes from an artery in the wrist.

Additional Notes

Lactate levels can be affected by medications, such as metformin, and certain medical conditions, such as liver disease. It is important to discuss any medications or medical conditions with your healthcare provider before having a lactate level test.
