A vitamin B1 test measures the amount of thiamine, a water-soluble vitamin your body needs to turn food into energy and keep nerves working properly. It is usually ordered when a person has symptoms or conditions that suggest low thiamine, such as poor nutrition, heavy alcohol use, or prolonged vomiting.

What it measures

  • Thiamine (vitamin B1) — The main vitamin level being checked in the blood.
  • Thiamine diphosphate — The active form of B1 that the body uses; often measured in red blood cells.
  • Erythrocyte transketolase activity — An enzyme test that indirectly shows how well B1 is working in cells.
  • Lactate and pyruvate — Substances that can rise when B1 is too low for normal energy use.

Who it is for

A clinician may order this test if you have symptoms such as numbness, confusion, or muscle weakness, or if you have a condition that raises your risk of low thiamine. It is not a routine screening test for most healthy adults.

Preparation

No fasting is usually required. Tell your clinician about all medicines and supplements you take, because some can affect the result.

Results and what they mean

Results are reported as a number with a reference range, and sometimes as a red blood cell measurement. Your clinician interprets the result along with your symptoms, diet, and other tests. This is general information only and is not medical advice; discuss your results with a qualified clinician.
