Vitamin B5 (Pantothenic Acid) Bioassay
Use
The Vitamin B5 (Pantothenic Acid) Bioassay is used to determine the level of pantothenic acid in serum, which is essential for various physiological functions. Pantothenic acid, also known as Vitamin B5, is crucial for the biosynthesis of coenzyme A, which is involved in fatty acid metabolism, energy production, and the synthesis of various other compounds necessary for cellular processes. Deficiency in pantothenic acid can lead to fatigue, insomnia, depression, irritability, vomiting, stomach pains, burning feet, and upper respiratory infections.
Special Instructions
Not provided.
Limitations
The assay's performance characteristics are limited by its validation through BioAgilytix Diagnostics, and it is not approved or cleared by the US FDA. The assay is sensitive to conditions like gross hemolysis, lipemia, or contamination, which can cause rejection of the specimen. The test may not be readily orderable for clients in New York State due to lack of approval there.
