What is this test?

This test measures pantothenate, a form of vitamin B5, in your urine and compares it with the amount of creatinine in the same sample. Creatinine is used as a reference because urine amounts and concentrations can vary from person to person.

Why might I need this test?

Your clinician may order this test if your symptoms or dietary history suggest a possible vitamin B5 deficiency. It may also be used to monitor nutritional status or treatment in certain clinical situations.

How is the test performed?

You provide a urine sample, which is sent to a laboratory for analysis. The laboratory measures pantothenate and creatinine and reports their relationship as a ratio.

How do I prepare for the test?

Follow your clinician's instructions about when to collect the urine sample. Tell the healthcare team about vitamin supplements, nutritional supplements, and major changes in your diet because they may affect the result.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

A low pantothenate-to-creatinine ratio may be consistent with low vitamin B5 intake or impaired absorption, but diet, recent supplementation, urine collection timing, and other factors can also affect the result. A high result may reflect recent vitamin intake or supplementation. Interpret the result alongside your symptoms, medical history, and other nutritional tests.

Frequently asked questions

What does this test measure?
It measures pantothenate (vitamin B5) in urine relative to creatinine. Creatinine helps adjust the result for differences in urine concentration.
Is this the same as a vitamin B5 blood test?
No. This test evaluates vitamin B5 in urine rather than directly measuring it in blood. Urine results may be influenced by recent intake and hydration.
Should I stop taking supplements before the test?
Do not stop prescribed supplements unless your clinician instructs you to do so. Tell the laboratory about supplements and other vitamin B5 sources so the result can be interpreted appropriately.
