A person who collects seven swabs in one vial is looking for ANY shedding. No, it cannot tell you how many days out of seven they are shedding, only that they shed at some point during that week. In your case, you could try that and see if during a week you are shedding virus at all. If the swab is negative, then, within the limits of the swab test, no virus was found. If the swab comes up positive, then you were shedding virus.
We not not aware of any research that confirms that any of those things is a trigger for herpes, and I am also not aware of any supplement that is known to reduce shedding or outbreaks in a significant statistical way including Lysine.
And yes, the swab she collected is PCR.
