ATAC PAK PHOSPHORUS REAGENT
The ATAC PAK Phosphorus Reagent Kit is intended for use with the ATAC Calibrator and the ATAC 8000 Random Access Chemistry System as a system for the quantitative determination of inorganic phosphorus in serum and plasma. Phosphorus results are used for the diagnosis and treatment of various disorders, including parathyroid gland and kidney diseases, and vitamin D imbalance.
The ATAC PAK Phosphorus Reagent determines phosphorus through its reaction with molybdate to form a phosphomolybdate complex. The resulting increase in absorbance at 340 nm is proportional to the phosphorus concentration in the sample.
Here's a breakdown of the acceptance criteria and the study details for the ATAC PAK Phosphorus Reagent Kit, based on the provided text:
1. A table of acceptance criteria and the reported device performance
