About This Topic

Vitamin B1 (Thiamine) is essential for energy metabolism and neurological function. Appropriate measurement is critical for diagnosing deficiencies that can lead to serious conditions, including permanent neurological damage, memory loss, and death. 

Vitamin B1 Supplementation Monitoring, Plasma (0080389) only measures recent dietary thiamine intake rather than body stores and should not be used for nutritional assessment.

Recommendation

Vitamin B1 (Thiamine), Whole Blood (0080388) reflects body stores and is the appropriate test for the nutritional assessment of thiamine.
