About this treatment
This blood test measures thiamine (vitamin B1) levels to detect deficiencies. Low levels can cause weakness, fatigue, nerve damage, and cardiovascular problems. The test is crucial for individuals with symptoms like fatigue or nerve issues, or those with inadequate thiamine intake. It helps diagnose deficiency, enabling timely treatment and lifestyle adjustments to prevent serious complications. Results are delivered via email and our Health Dashboard.

Who is this for?
Vegetarians and vegans (at higher risk of B12, iron, and zinc deficiency). Older adults, as nutrient absorption decreases with age. Anyone on restrictive diets or with digestive conditions affecting absorption. People experiencing unexplained fatigue, brain fog, poor wound healing, or hair loss. Athletes with high nutrient demands from training.
Preparation Required
Fasting for 8–10 hours is recommended for some nutrient tests but not all — check with your provider. Continue taking your regular supplements unless told otherwise (the test measures your steady-state levels). Morning draws are preferred for consistent results.
Panel Categories
Biomarkers Tested
3Essential for DNA synthesis, cell division, and red blood cell formation. Folate deficiency causes megaloblastic anemia and, during pregnancy, increases the risk of neural tube defects. Works closely with vitamin B12.
Essential for nerve function, DNA synthesis, and red blood cell formation. B12 deficiency can cause anemia, neuropathy, fatigue, and cognitive impairment. Common in vegans, vegetarians, older adults, and those taking metformin or acid-reducing medications.
Essential for energy metabolism and nervous system function. Thiamine deficiency can cause beriberi (nerve damage) and Wernicke-Korsakoff syndrome. Common in chronic alcohol use and malabsorption conditions.
