VITAMIN B1 (THIAMIN)

The VITAMIN B1 (THIAMIN) test measures blood thiamine status to detect deficiency that can impair energy metabolism, nerve function, and cardiovascular health. The analysis is performed on a blood sample collected at home by a trained phlebotomist and processed in accredited UAE laboratories using validated methods for accurate results. Early identification of low thiamine helps guide dietary changes or targeted supplementation to relieve symptoms such as fatigue, numbness, or muscle weakness and to prevent more serious complications.
