An ELISA assay was performed on a patient's serum sample.What is the relationship of the amount of enzyme activity to the amount of patient analyte measured?

Question

Quizplus · Accepted Answer

In an ELISA assay, the amount of enzyme activity is directly proportional to the amount of patient analyte measured. This is because the more analyte present in the sample, the more enzyme reaction will occur, leading to a greater signal and a higher measurement of the analyte concentration. Therefore, the two quantities are directly proportional.
