What is an Antibody Rapid Test Card?
An Antibody Rapid Test Card is a lateral flow immunochromatographic assay designed to qualitatively detect the presence of specific antibodies in a sample. These tests typically use antigen-coated membranes and labeled detection systems to produce visible results within minutes.

Scientific Principle: Lateral Flow Immunoassay (LFIA)
Antibody rapid test cards operate using lateral flow immunoassay (LFIA) technology, a widely used platform in molecular biology and diagnostic research.
Key Components:
-
Sample pad
-
Conjugate pad (labeled antibodies or antigens)
-
Nitrocellulose membrane
-
Test line (T line)
-
Control line (C line)

How Antibody Rapid Test Cards Work
The test operates through capillary action:
-
A sample is applied to the sample pad
-
The sample migrates along the membrane
-
Antibodies (if present) bind to labeled antigens
-
Complexes are captured at the test line
-
A visible line indicates a positive signal
