Overview of the Vitamin B1 (Thiamine) Test
The Vitamin B1 blood test measures Thiamine status, providing information about a water-soluble vitamin essential for energy production and normal neurological function.
The test assesses 1 nutritional biomarker: Vitamin B1 (Thiamine).
Thiamine is required to process carbohydrates and convert nutrients into usable cellular energy.
Its active form acts as a cofactor for several enzymes involved in glucose metabolism.
The brain and nervous system are particularly dependent on these energy pathways.
The body stores relatively little Thiamine, so deficiency can develop faster than deficiencies of nutrients with larger body stores.
Risk is increased by severe nutritional restriction, persistent vomiting, malabsorption, bariatric surgery and heavy alcohol use.
Severe deficiency can cause beriberi or Wernicke encephalopathy.
Wernicke encephalopathy is a medical emergency and classically involves confusion, abnormal eye movements and impaired coordination, although not every feature is always present.
Cardiovascular effects can also occur in severe Thiamine deficiency.
Routine fatigue alone is not specific enough to diagnose deficiency.
The result should be interpreted with nutritional history, symptoms and relevant clinical risk factors.
What Does the Vitamin B1 (Thiamine) Test Check?
The test measures Vitamin B1 status. This test measures 1 biomarker.
Vitamin B1 (Thiamine)
Measures Thiamine status, supporting assessment of a vitamin required for carbohydrate metabolism, cellular energy production and normal nerve function.
Who May Benefit From the Vitamin B1 (Thiamine) Test?
Thiamine testing can be useful where nutritional deficiency or impaired absorption is suspected.
People with severe dietary restriction or poor nutritional intake - Limited Thiamine intake can lead to deficiency.
People with prolonged vomiting - Persistent vomiting can rapidly reduce nutritional stores.
People with significant alcohol dependence or long-term excessive alcohol intake - Thiamine deficiency risk can be substantially increased.
People following bariatric surgery - Reduced intake or absorption can increase deficiency risk.
People with malabsorption disorders - Gastrointestinal disease can impair nutrient uptake.
People with unexplained neurological symptoms and nutritional risk - Thiamine deficiency can affect the nervous system.
People receiving long-term nutritional support - Vitamin status may require specialist monitoring.
People with a previous low Thiamine result - Repeat testing can assess response to treatment.
How to Prepare
Do not delay medically necessary Thiamine treatment in someone at risk of Wernicke encephalopathy simply to obtain a baseline result.
Symptoms and Reasons to Consider the Vitamin B1 (Thiamine) Test
Early deficiency can be non-specific, while severe deficiency can produce neurological or cardiovascular disease.
Persistent fatigue with significant nutritional risk - Thiamine is required for normal cellular energy metabolism.
Tingling or peripheral nerve symptoms - Severe deficiency can affect peripheral nerves.
Muscle weakness - Neuromuscular symptoms can occur with deficiency.
Poor balance or coordination - Severe neurological deficiency can affect gait and coordination.
Prolonged vomiting - Rapid nutritional depletion can occur.
Heavy alcohol use with poor nutrition - This is an important risk factor for clinically significant deficiency.
Confusion, abnormal eye movements or severe balance problems in a person at risk of Thiamine deficiency can indicate Wernicke encephalopathy and require urgent medical treatment.
Treatment should not be delayed while waiting for a routine blood-test result where severe deficiency is clinically suspected.

When Will I Receive My Results?
The current live London Blood Tests page lists a turnaround of approximately 2 days after laboratory receipt for Vitamin B1 (Thiamine).
The sample undergoes specialist vitamin analysis, quality-control procedures and result authorisation.
Understanding Your Results
A low result can indicate reduced Thiamine status.
The clinical significance is greatest when compatible symptoms or recognised nutritional risk factors are present.
A result within range suggests measured Thiamine status is within the laboratory's expected interval.
A high result is commonly associated with supplementation.
Because Thiamine is water soluble, excess intake is generally excreted, although the laboratory number should still be interpreted according to supplement use.
Where severe deficiency is clinically suspected, treatment decisions should not depend solely on laboratory confirmation.
