Herpes is a viral infection that affects the skin and mucous membranes. While the virus can be present in urine, it is not typically used as a diagnostic sample for herpes.
The most common way to diagnose herpes is through a physical examination and testing of fluid from a blister or sore. This can include a culture test or a polymerase chain reaction (PCR) test, which can detect the DNA of the herpes virus.
It is important to note that even if the herpes virus is not detected in urine, it can still be present in other bodily fluids and can be transmitted to others through sexual contact or contact with infected skin or mucous membranes. If you suspect that you may have herpes or have been exposed to the virus, it is important to speak with a healthcare professional for testing and treatment options.
