The technique which could prove that a patient was exposed to a certain virus is: the plaque reduction neutralization test (PRNT). This technique can expose the virus even if it is no longer in their system.
<h3>What is a plaque reduction neutralization test?</h3>
The plaque reduction neutralization test, also known as PRNT, is used to measure the patient’s antibody ability to neutralize the virus and protect their cells from infection. Using the PRNT, the nurse can test their patient’s ability to neutralize the virus, even if it does not exist in their system anymore. This test is very effective in giving information about the virus exposure history of the patient.
