Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Lactic acidosis is a serious metabolic condition characterized by the excessive accumulation of lactic acid in the blood, which can lead to a dangerous drop in blood pH. This condition requires prompt diagnosis and treatment, as it can be life-threatening if left untreated.
Recommended Test
Lactic Acid, Plasma
This test directly measures the concentration of lactic acid in the blood plasma. When lactic acid levels become excessively high, it indicates lactic acidosis, which can occur due to various underlying conditions such as heart failure, cancer, sepsis, respiratory failure, or severe physical exertion. This test is essential for both diagnosing the condition and monitoring treatment effectiveness.

Diagnosing Lactic Acidosis
Lactic acidosis is directly diagnosed through blood testing that measures the concentration of lactic acid in the bloodstream. Since symptoms can be nonspecific and may overlap with other metabolic disorders, laboratory confirmation is essential for accurate diagnosis and appropriate treatment.
Understanding the Results
Elevated lactic acid levels in the blood can indicate that the body's cells are not receiving adequate oxygen or that there is a problem with cellular metabolism. The test results help healthcare providers identify the underlying cause and determine the most appropriate treatment approach.
Important Considerations
