Vitamin B1 (Whole Blood) Testing

B1 Vitamin, Thiamine
Sample Report
Specimen Type: Blood


The Vitamin B1 test (whole blood) may be used to determine Vitamin B1 deficiency. Vitamin B1 deficiency may be caused by malnutrition or those with malabsorption disorders such as celiac disease. As Vitamin B1 (or Thiamine) is found mostly in red blood cells, the Vitamin B1, Whole Blood test is typically used to evaluate stores within the body. Vitamin B1 (or Thiamine) is required to properly convert carbohydrates to energy. 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.

Incubation Period:


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