This reagent is intended to be used by trained personnel in a professional setting and is not intended for home use.

The ATAC Calibrator Kit is intended to calibrate the ATAC Clinical Systems for the quantitative determination of albumin, calcium, cholesterol, creatinine, glucose, magnesium, phosphorus, total protein and urea nitrogen.

The ATAC Calcium Reagent Kit, the ATAC Calibrator and the ATAC 8000 Random Access Chemistry System are intended for use as a system for the quantitation of calcium in serum and plasma. Calcium results are for the diagnosis and treatment of parathyroid disease, a variety of bone disease and tetany (intermittent muscular contractions or spasms).

The ATAC Calcium Reagent Kit is intended for the quantitative determination of calcium in serum and plasma. Calcium results are for the diagnosis and treathyroid disease, a variety of bone diseases, chronic renal disease and tetany (intermittent muscular contractions or spasms). The ATAC Calcium Reagent determines calcium through binding by o-cresolphthalein complexone at alkaline pH. The resulting increase in absorbance at 578 nm is proportion al to the calcium concentration of the sample.

Magnesium results are used for the diagnosis and treatment of hypomagnesemia (abnormally low plasma levels of magnesium) and hypermagnesemia (abnormally high plasma levels of magnesium).

The ATAC PAK Magnesium Reagent determines magnesium through its selective binding by xylidyl blue to form a red-purple chelate. The resulting increase in absorbance at 510 nm is proportional to the magnesium concentration in the sample.

The ATAC PAK Albumin 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 albumin in serum and plasma. Albumin results are used for the diagnosis and treatment of numerous diseases involving primarily the liver or kidneys.

The ATAC PAK Albumin Reagent Kit is intended for the quantitative determination of albumin in serum and plasma. Albumin results are used for the diagnosis and treatment of numerous diseases involving primarily the liver or kidneys. The ATAC PAK Albumin Reagent determines albumin by the selective binding of bromcresol green. The resulting increase in absorbance at 630 nm is proportional to the albumin concentration in the sample.

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.

The ATAC Creatinine Reagent Kit, the ATAC Calibrator and the ATAC 8000 Random Access Chemistry System are intended for use as a system for the quantitative determination of creatinine in serum, plasma and urine. Creatinine results are used in the diagnosis and treatment of renal dialysis and as a calculation basis for measuring other urine analytes.

The ATAC PAK Creatinine Reagent Kit is intended for the quantitative determination of creatinine in serum, plasma and urine. Creatinine results are used in the diagnosis and treatment of renal diseases, in monitoring renal dialysis and as a calculation basis for measuring other urine analytes. The ATAC PAK Creatinines creatinine through the reaction of creatinine with alkaline picrate. The initial rate of absorbance increase at 510 nm is proportional to the creatinine concentration of the sample.

The ATAC PAK BUN Reagent Kit is intended for the quantitative determination of urea nitrogen in serum, plasma and urine. Urea nitrogen results are used in the diagnosis and treatment of certain renal and metabolic diseases.

The ATAC PAK BUN Reagent determines urea nitrogen through the enzymatic action of urease and glutamate delydrogenase. The resulting decrease in absorbance at 340 nm is proportional to the urea nitrogen concentration of the sample.

The ATAC Direct LDL Reagent Kit, the ATAC Direct LDL Calibrator and the ATAC 8000 Random Access Chemistry System are intended for the quantitative determination of LDL-cholesterol in serum and plasma. LDL-cholesterol measurements are used in the diagnosis and treatment of lipid disorders (such as diabetes mellitus), atherosclerosis, and various liver and renal diseases, and for the assessment of the risk of developing cardiovascular disease.

The ATAC Direct LDL Reagent determines LDL-cholesterol through a two step reaction, which specifically consumes non-LDL cholesterol in a series of reactions without producing color. In the second reaction step, the chromogen is added, and a second detergent solubilizes the LDL-cholesterol, allowing it to react with cholesterol oxidase, cholesterol esterase and peroxidase in the reagent to produce a color that is proportional to the amount of LDL-cholesterol in the sample.
