Organic Acids Profile (24-hour urine)

This test helps your healthcare provider learn important information about your health. It can show how well certain parts of your body are working, help find the cause of symptoms you may be having, and guide decisions about the care and treatment that are right for you.

Your healthcare provider may recommend this test if you have symptoms like frequent fatigue, muscle weakness, developmental delays, or unexplained health issues that suggest metabolic problems. It’s also used in newborn screening or when evaluating conditions like organic acidemias.

Before the test, your healthcare team will explain the procedure and answer any questions you have. You may receive specific instructions, such as when to stop eating or drinking, which medicines to take or hold, and what time to arrive. Following these directions carefully helps make sure the test can be done safely and accurately.

You’ll collect all urine produced in a 24-hour period in a special container. Drink plenty of water to ensure you produce enough urine, but avoid foods or supplements that might interfere with the test results (like certain vitamins or medications).

During the test, a trained member of your care team will carry out the procedure while keeping you as comfortable as possible. The length of the test depends on the type being performed, and your team will explain each step as it happens. Tell them right away if you feel pain, dizziness, or any other discomfort.

After collecting your urine sample, it’s sent to a lab for analysis using advanced techniques like high-performance liquid chromatography (HPLC). This identifies and measures specific organic acids in your urine.

Your results will show whether your values fall within the expected range for this test. Results within the normal range may mean no further testing is needed at this time, while results outside that range can help your provider identify a possible condition or decide whether more evaluation is needed. Your provider will review the results with you and explain what they mean for your care.

Abnormal results may indicate imbalances in how your body breaks down certain acids, which can point to metabolic disorders. Your provider will discuss the findings with you and may recommend further testing or treatment.
