A lactic acid test is a blood test that measures the level of lactic acid made in the body. Most of it is made by muscle tissue and red blood cells.When the oxygen level in the body is normal, carbohydrate breaks down into water and carbon dioxide. test for lactic acid is done to: 1  Check for lactic acidosis. 2  See whether the right amount of oxygen is reaching the body's tissues. 3  Find the cause for a high amount of acid (low pH) in the blood.
Elevated lactate levels can affect your heart rhythm. Lactic acid is a by-product of the process cells use to produce energy. As cells convert glucose to energy, they use oxygen. If there is not enough oxygen within the cell, the cell is still able to produce energy, but also produces lactic acid. The cells releases lactic acid into the blood, where it is converted to a similar molecule called lactate. High lactate levels within the blood can harm your cells, the University of New Mexico warns.
