Principle
Proteins react with cupric ions under alkaline pH to produce a color complex. This color complex absorbs light at 546 nm.(530-570 nm.). The intensity of the color is directly proportional to the protein concentration in the specimen.

Quality Control
To ensure adequate quality control, it is recommended that each batch should include a normal and an abnormal commercial reference control serum. It should be realised that the use of quality control material checks both instrument and reagent functions together. Factors which might affect the performance of this test include proper instrument function, temperature control, cleanliness of glassware and accuracy of pipetting.
Other Details
Vaļue is stable in serum for 24 hours at 2-8°C and 30 days
when stored at-20°C.
