real simply just to give you an idea:

“probe” is a chemical that attaches to the target replicated allow the test to receive a some sort of chemical mechanism for identifying test outcome. could be something like a color.

primer attaches to the gene or base pair location that will start the sequence to be tested or replicated to amplify the suspected presence of the virus. it’s the amplification that gives the probe it’s power and sensitivity to detect.

any contamination renders the test always positive and completely useless.

so they are no danger to patients or workers.

hope that helps
