Vitamin B1 Test

A Vitamin B1 test, also known as a thiamine test, measures the levels of Vitamin B1 in the blood. Vitamin B1 is an essential nutrient that plays a key role in converting food into energy and maintaining a healthy nervous system.

A Vitamin B1 test may be ordered by healthcare providers if they suspect a deficiency in Vitamin B1, which can lead to symptoms such as fatigue, muscle weakness, confusion, and nerve damage. Causes of Vitamin B1 deficiency include inadequate dietary intake, chronic alcohol use, and certain medical conditions that affect absorption or metabolism of the vitamin.

The test typically involves a simple blood draw, and results can help determine if supplementation or dietary changes are needed to correct a Vitamin B1 deficiency.
