Understanding Lab Tests for Beriberi
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Beriberi is a serious nutritional disorder caused by a deficiency of thiamine (vitamin B1) in the diet. This condition affects both the cardiovascular and nervous systems, leading to symptoms such as weight loss, emotional disturbances, weakness in the limbs, irregular heartbeat, and swelling of body tissues.
Recommended Test
Vitamin B1 (Thiamine) LC/MS/MS
This specialized test uses liquid chromatography-tandem mass spectrometry (LC/MS/MS) to accurately measure thiamine levels in the blood. Low thiamine levels confirm the diagnosis of beriberi and help healthcare providers determine the severity of the deficiency. This test is crucial for diagnosing beriberi, as the condition directly results from inadequate thiamine levels affecting the cardiovascular system and nervous system.

Diagnosing Beriberi
Since beriberi symptoms can overlap with other medical conditions, a definitive diagnosis requires laboratory testing to measure thiamine levels in the blood. This testing is essential to confirm the deficiency and guide appropriate supplementation therapy.
Understanding Your Results
Low thiamine levels in the blood confirm a vitamin B1 deficiency that can lead to beriberi. Early detection and treatment with thiamine supplementation can help prevent progression of symptoms and reverse many of the condition's effects on the heart and nervous system.
