What this test is
This test checks the amount of vitamin B2, also called riboflavin, in a sample of blood or urine. It can help show whether a person's riboflavin level is lower than expected. The test is not a routine screening for most people and is usually ordered when a deficiency is suspected.
What it measures
- Riboflavin (vitamin B2) level — reflects the amount of this vitamin present in the sample
- Erythrocyte glutathione reductase activity — an enzyme test sometimes used to estimate riboflavin status
- Urinary riboflavin — reflects recent riboflavin intake and excretion
What the test involves
The sample is usually collected with a standard blood draw from a vein in the arm. In some cases, a urine sample may be collected instead, depending on the lab and the reason for testing.
Why it is often ordered
A clinician may order this test when a person has symptoms that could be related to low riboflavin, such as cracks at the corners of the mouth, a sore tongue, or certain skin and eye changes. It may also be ordered for people who have trouble absorbing nutrients or who follow a limited diet.
Preparation
Preparation can vary, so follow the instructions provided by the collection lab. Ask the lab whether fasting or avoiding certain foods or supplements is needed before the sample is taken.
How results are reported
Results are reported as a measured level of riboflavin or a related marker, and the lab report will include its own reference range. Reference ranges differ from lab to lab, so a result should always be interpreted using the range provided by the testing laboratory.

Who might need a vitamin B2 test?
This test is not part of routine care for most people. It may be considered when a person has signs that could point to a deficiency or has a health condition that makes it hard to absorb nutrients. A clinician decides whether testing is appropriate.
