Overview
The purpose of the Pyruvate Pyruvic Acid Test is to measure the concentration of pyruvate in the blood, which is crucial for evaluating the body's energy metabolism. It helps identify whether the body is appropriately breaking down glucose for energy and is particularly useful in diagnosing mitochondrial disorders, pyruvate dehydrogenase deficiency, and other metabolic conditions. This test is often performed with a lactate test to calculate the lactate-to-pyruvate ratio.

How to Prepare
- Collect 3 mL (2 mL min) whole blood in a Grey Top (Sodium Fluoride) tube.
- Mix whole blood immediately with an equal volume of 7% Perchloric Acid.
- Mix well and centrifuge immediately.
- Separate the supernatant and submit a minimum of 2 mL.
- Ship the sample refrigerated or frozen.
Doctor's Notes
Reviewed by Dr SHAILAJA RAGHUNATH MURDESHWAR — MBBS, MD (General Medicine) · Reg. No. 8052
"Pyruvate testing is often essential in evaluating children with suspected metabolic myopathies or encephalopathies. It should be combined with lactate measurement for accurate interpretation."

Test Parameters & Specifications
Sample Stability
- Clotted sample
- Sample not mixed with perchloric acid
- Delayed centrifugation
- Hemolyzed specimen
- Insufficient sample volume
Understanding Your Results
High lactate-to-pyruvate ratio (>20) suggests a defect in the electron transport chain or pyruvate carboxylase deficiency.
Normal ratio may suggest pyruvate dehydrogenase deficiency or disorders of pyruvate metabolism.
Significant mitochondrial/metabolic disease is less likely.
If you are experiencing unexplained fatigue, muscle weakness, seizures, developmental delays, or any neurological symptoms, consult a physician. A doctor can determine whether a pyruvate test is suitable for you and help interpret the results.
Limitations
- ⚠A single pyruvate level is not diagnostic and should be interpreted in the context of lactate and clinical findings.
- ⚠Strict preanalytical conditions are necessary; otherwise, results may be falsely elevated or depressed.
Risks & Considerations
- ●Slight pain or bruising at the injection site
- ●Dizziness
- ●Rare risk of infection
Interfering Factors
- ●Hemolysis of the blood sample
- ●Delayed handling of the sample
- ●Failure to immediately mix with perchloric acid
- ●Prolonged tourniquet application
- ●Recent exercise before blood collection
