The High-Dose Hook Effect

Why can an extremely high analyte concentration produce a deceptively low test result? Follow the binding process and see where the assay breaks down.

01 Watch the test-line signal increase through the normal analytical range.
02 See how excess analyte prevents the expected sandwich complex from forming.
03 Understand why dilution and repeat testing can reveal a suspected hook effect.
