plasma creatinine analysis by Jaffe reaction with spectrophotometric readout +
A method for assaying the creatinine in plasma (the fibrinogen-containing fluid portion of the blood in which the particulate components are suspended) using the Jaffe reaction, the reaction of creatinine and picric acid in an alkaline solution, followed by quantitation of the colorimetric readout using a spectrophotometer at 520 nm. The assay can be performed without the removal of proteins from the sample, or in combination with such removal which reduces the possibility of interference from proteinaceous chromogens.
