Vitamin A (Retinol) analysis using High-Performance Liquid Chromatography (HPLC) is an important test used to measure Vitamin A levels in the blood. Vitamin A is essential for eye health, boosting immunity, and supporting growth and development. A blood sample is collected and sent to the laboratory, where it is analyzed using HPLC technology, which allows for precise measurement of retinol concentration. This test is recommended in cases of vitamin deficiency or when symptoms such as vision problems or weakened immunity appear. The analysis helps doctors assess the patient's nutritional status and adjust the diet or supplements as needed to ensure healthy levels of Vitamin A.
