Lactic Acid (blood test )

 What is a lactic acid test? This test measures the level of lactic acid, also known as lactate, in your blood. Lactic acid is a substance made by muscle tissue and by red blood cells, which carry oxygen from your lungs to other parts of your body. Normally, the level of lactic acid in the blood is low. 

What blood test checks lactic acid?

The lactate blood test is primarily ordered to help determine if someone has lactic acidosis, a level of lactate that is high enough to disrupt a person's acid-base (pH) balance. Lactic acidosis is most commonly caused by an inadequate amount of oxygen in cells and tissues (hypoxia).
