The Vitamin B1 test measures Thiamine Pyrophosphate (TPP), the active, functional form of Vitamin B1, directly from EDTA whole blood. Thiamine plays a key role in Nerve conduction, Energy production, Muscle health, Brain function, and Glucose metabolism.

Low Vitamin B1 levels can cause fatigue, muscle weakness, nerve pain, numbness, memory issues, and metabolic problems.

At Torrent Diagnostics, the Vitamin B1 test is conducted using high-precision biochemical methods that align with Global Standard laboratory practices.

Why is the Vitamin B1 Test Done?

  • Detecting Thiamine Deficiency

Thiamine deficiency may occur due to:

  • Poor dietary intake
  • Chronic illness
  • Malabsorption
  • Excessive alcohol intake
  • Long-term medication use
The Vitamin B1 test detects deficiency early to prevent complications like neuropathy and cardiovascular issues.

Evaluating Nerve and Muscle Function

B1 is essential for nerve conduction and muscle coordination.
This test helps evaluate:
  • Tingling or numbness
  • Burning sensations in feet
  • Muscle cramps or weakness
  • Difficulty walking
  • Neuropathy symptoms
Doctors often order this test when neurological symptoms appear without a known cause.
Assessing Metabolic Health
Thiamine is central to carbohydrate and energy metabolism. Deficiency may contribute to:
  • Extreme fatigue
  • Appetite loss
  • Weight loss
  • Lactic acidosis
  • Brain fog or confusion
The Vitamin B1 test helps pinpoint metabolic dysfunction early.

How to Read Vitamin B1 (Thiamine Pyrophosphate) Test Results?

Normal TPP Levels (Ranges vary by laboratory and method)
Level Category Reference Range (approx.)
Normal 70-180 nmol/L RBC
Borderline 60-70 nmol/L RBC
Low / Deficient < 60 nmol/L RBC
(Final range depends on Torrent Diagnostics platform calibration.)  

Low Thiamine Levels May Indicate

  • Chronic alcohol dependence
  • Malabsorption (celiac, IBD)
  • Poor nutrition
  • Long-term vomiting
  • Post-gastric surgery
  • High carbohydrate intake with low B1
  • Long-term diuretic therapy

Further tests may include:

  • Other B-vitamins (B2, B6, B12)
  • Folate levels
  • CBC for anemia
  • Metabolic markers

Factors Influencing Vitamin B1 Levels

May lower levels:

  • Chronic illness
  • Excess alcohol
  • Aging
  • Long-term medications
  • Pregnancy
  • May raise levels artificially:
  • Recent supplementation
