Question

In a typical competitive immunoassay, how does the measured signal relate to the concentration of patient analyte?

Accepted Answer

보기 3: Signal decreases as patient analyte concentration increases

Patient analyte competes with labeled analyte for limited binding sites. More patient analyte generally means less label is bound and a lower signal.

Answer

보기 1: Signal remains constant regardless of analyte concentration

Answer

보기 2: Signal increases linearly with increasing patient analyte concentration

Answer

보기 4: Signal initially rises then plateaus at high analyte levels

In a typical competitive immunoassay, how does the measured signal relate to the concentration of patient analyte?
