Just looking for insight

Hi All,

My girlfriend of the past few months at my request got an STD test. It was an IGG which was taken in the second week of may, her results came back positive for both types of HSV. The scores were HSV-1 over 5.0 and HSV-2 was 3.6 as you can imagine we were both startled. She spoke to her Ex due to her having no symptoms or outbreaks. The last time they had been together was in early February, he got tested which came back negative. So she waited 1 month and retested which came back negative for both types of HSV. She was given the generic form of a herpes medication but only took it for 5 days and decided to not take it until she was retested. Should I trust this test as it was taken in June and her last sexual contact with anyone else was in early February. Could the first test just have been a false positive? Her retest was at the 4 month mark and it was negative for both.
