Low levels of chromatic substances cause severe interference with traditional phosphorus assays. Even clear sera may contain high levels of free fatty acids, phospholipids or abnormal proteins which form turbidity during the course of traditional assays.Phosphorus assays have been used to monitor intravenous nutrition in geriatric poulations receiveing Intralipid. The Intralipid causes severe interference in traditional phosphorus assays providing misleading information.The Synermed phosphorus assay avoids interference from abnormal proteins, chromatic substances and other turbidity related interferences by means of kinetic infrared detection.Liquid-Stable Ready-to-Use ReagentsMinimal Interference from Serum Bilirubin, Hemoglobin and LipemiaAvoids Error from Abnormal Proteins
