What is a Rapid Antigen Detection Test and how does it work?

Expert Solution

Rapid Antigen Detection Test (RADT)

Rapid Antigen Detection Test is a diagnostic test
It detects the presence or absence of an antigen
It is an immunochromatographic
Result can be seen with naked eye
Since freign antogen is already present after an infection, it is more faster. Because on dont want to wait for antibody to develop

Working of RADT

Sample is applied on an antibody coated strip
Antibodies on the strip are coated with fluorophore
Fluorophore allow to detect the presence of antigen
When antigen containing sample is applied, it will attach to the antigen.
This antigen is then again passes throug another area containing antibodies against the antigen.
These antibodies attached to the antigen are detected to confirm the presence of antigen
This process is less time consuming, efficient and reliable
