The Vitamin B5 (Pantothenic Acid) by LC-MS/MS test is a laboratory procedure used to measure the levels of pantothenic acid in the blood. Vitamin B5 is essential for energy metabolism and hormone synthesis, playing a vital role in various biochemical processes in the body. A blood sample is collected and sent to a laboratory where it is analyzed using LC-MS/MS (Liquid Chromatography-Tandem Mass Spectrometry), a highly accurate technique that provides precise measurements of vitamin concentrations. This test is recommended in cases of suspected vitamin B5 deficiency or when symptoms such as persistent fatigue or general weakness are present. The results help doctors assess the patient’s nutritional status and determine whether supplementation or dietary adjustments are necessary to maintain healthy levels of Vitamin B5, thereby supporting overall health and energy levels.
