immunoassays
Antibody detection methods
Immunoassays are laboratory tests that use antibodies to detect and measure specific substances—hormones, drugs, proteins, or pathogens—in blood, urine, or other samples.
The antibody binds to its target molecule, producing a measurable signal.
Pregnancy tests and COVID rapid tests are common immunoassays.
The immunoassays came back positive for the virus.
