Diagnosis
A doctor might start by examining your physical symptoms before making a diagnosis of herpes on the buttocks.
Physical exam
A medical professional might perform a herpes virus test on you if they notice red, itchy bumps or blisters along with other symptoms like fever, body aches, or swollen lymph nodes.
Test of a fluid sample
A diagnosis of any type of herpes must be supported by laboratory tests. If your blisters or sores are oozing fluid, a medical professional can collect a sample and send it to a lab for analysis. Herpes will be detected in the fluid, as well as the type of HSV that is causing the infection.
