What is this test?

The amino beta guanidinopropionate test measures how much of a specific amino acid compound called beta-guanidinopropionic acid is present in your urine. This compound is related to creatine, which is important for muscle energy metabolism. The test requires a 24-hour urine collection, meaning all urine produced during a 24-hour period must be collected.

How is the test performed?

You will receive a special collection container from your healthcare provider. On the day of collection, you will begin by urinating into the toilet (not the container) when you wake up. After that, every time you urinate for the next 24 hours, you will collect the urine in the provided container. Keep the container refrigerated. At the end of 24 hours, bring the complete collection to your laboratory or healthcare provider as instructed.

How to prepare for the test?

Your healthcare provider may ask you to avoid certain foods or supplements before the test. Inform your doctor about all medications you are taking. Avoid strenuous exercise during the collection period, as it may affect test results. Drink normal amounts of fluids unless otherwise instructed.

Frequently asked questions

Why do I need to collect urine for 24 hours?
A 24-hour collection provides a more accurate picture of how much of the compound your body is excreting, as levels can vary throughout the day. A single urine sample might not represent your true average.
What happens if I miss a urine sample during the 24-hour period?
Contact your healthcare provider or laboratory for guidance. In most cases, the collection should be restarted, as an incomplete collection may produce inaccurate results.
Is this test painful?
No. The test only requires you to urinate into a collection container. There are no needles or invasive procedures involved.
How long will it take to get results?
Results typically take a few days to a week, depending on the laboratory. Your healthcare provider will contact you with the results.
