Glutaric Acid (Mass Concentration) in Serum/Plasma

Published: August 9, 2026Updated: August 16, 2026

This test measures the amount of glutaric acid, a naturally occurring organic acid, in your blood. It helps diagnose conditions like glutaric acidemia, a rare inherited metabolic disorder.

Why This Test Is Done

Your doctor may order this test if you have symptoms like slow movement, trouble walking, or developmental delays. It’s also used in newborn screening programs for certain genetic conditions.

What to Expect Before the Test

No special preparation is needed. You may have a small needle inserted into your arm or vein to draw blood. If testing urine, you might be asked to collect a sample at home or in a clinic.

What the Results Mean

High levels of glutaric acid in blood or urine can suggest inherited metabolic disorders. Low levels are less commonly tested for but may be checked in specific genetic evaluations.

Common Conditions Linked to Abnormal Results

Elevated levels may be linked to glutaric acidemia, a rare genetic disorder causing problems with energy production in cells. Urine testing can also detect this condition early.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What causes glutaric acid to build up in the body?
Glutaric acid buildup is primarily due to genetic mutations that affect enzymes responsible for breaking down certain acids. These mutations are inherited and can cause metabolic disorders.
How often should I get this test if I have a family history of glutaric acidemia?
If you have a family history, your doctor may recommend regular monitoring, including periodic blood or urine tests, to track levels and manage symptoms proactively.
Can diet changes help with glutaric acid levels?
Yes, in some cases, dietary modifications (like reducing certain amino acids) may help manage symptoms in people with glutaric acidemia, but this depends on individual medical advice.
