Can herpes be positive then negative?

A person who only has HSV-1 may receive a false positive for HSV-2. IgM tests sometimes cross-react with other viruses in the same family, such as varicella zoster virus (VZV) which causes chickenpox or cytomegalovirus (CMV) which causes mono, meaning that positive results may be misleading.
