Product details.

Intended use: Creatinine (Kinetic) (R1-R2) is a reagent kit for the quantitative estimation of creatinine in serum or urine by a modified Jaffe method, with no deproteinisation. Creatinine reacts with alkaline picrate to form a coloured complex, and the rate of its formation, read at 510 nm, is proportional to creatinine concentration. Manufactured at Reckon’s Vadodara facility under ISO 13485:2016 quality management, and released against reference standards before dispatch.

Procedure at a glance4 steps

Mix equal volumes of 1 Creatinine and 2 Creatinine as the working reagent.
Pipette 1.0 ml of working reagent into the standard and test tubes; add 0.1 ml of standard and of sample to their tubes, mix and aspirate.
Read the standard and test at 510 nm at 20 seconds (ST1, TS1) and again at 80 seconds (ST2, TS2), against distilled water.
Creatinine (mg/dl) = (TS2 − TS1) ÷ (ST2 − ST1) × 2; multiply by 88.5 for µmol/L.
