Vitamin B1 Blood Test

This test measures levels of Vitamin B1 in the blood.  B1 or Thiamine is one of several B vitamins which the body uses in metabolism, energy production and the healthy development of skin, bones, muscles, organs and nervous system.  B Vitamins are taken in through a person's diet.  Good sources of Vitamin B1 include cereals, whole grains, potatoes, pork, seafood, nuts and legumes.  Deficiencies are rare but are typically associated with malnutrition, alcoholism, and malabsorption disorders such as Celiac Disease.  Chronic B1 deficiency can affect the muscles, heart and nervous system.  B Vitamin toxicity is rare.

This test is typically ordered when a person has symptoms of B Vitamin deficiency such as irritability, skin rash, fatigue, insomnia, numbness or tingling in the hands and feet, and sores on the lips or in the mouth. 

For additional testing options, please see our Vitamin Testing Category.

Turnaround time for the Vitamin B1 test is typically 2-3 business days.

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.


The Vitamin B1 test requires that the sample be collected before breakfast in the morning and prior to any medication.
