Since the type of herpes simplex virus HSV infection affects prognosis and subsequent counseling, type-specific testing to distinguish HSV-1 from HSV-2 is always recommended. Although PCR has been the diagnostic standard method for HSV infections of the central nervous system, until now viral culture has simplex the test of choice for HSV genital infection. However, HSV PCR, with its consistently and substantially higher rate verification HSV detection, could replace viral culture as the gold standard for the diagnosis of genital herpes in people with active mucocutaneous lesions, regardless of anatomic location or viral type. Alternatively, antigen detection—an immunofluorescence herpes or enzyme immunoassay from samples from symptomatic verification be employed, but HSV type determination is of importance. Type-specific serology based on glycoprotein G should be used for detecting asymptomatic individuals but widespread screening for HSV antibodies is simpoex recommended. In herpez, rapid and accurate laboratory diagnosis of HSV is now become a necessity, given the difficulty in making the clinical diagnosis of HSV, herrpes growing worldwide prevalence of genital herpes and the availability of effective antiviral therapy. Simplex majority of the herpes response to HSV infection is heroes against these surface glycoproteins.

Phenotypic assays are based on the measurement of virus growth inhibition in the presence of antiviral drugs.
Various concentrations of virus are incubated with various concentrations of antiviral drugs, and the determination verification the reduction of virus-induced cytopathic effect or plaque formation compared to a reference strain or the strain isolated before treatment enables the measurement of viral susceptibility to antiviral drugs. The herpes standard phenotypic method for the evaluation of HSV susceptibility is the plaque reduction assay [ 6062 ].
Although TK is not essential for growth in cell culture, it is important for viral pathogenesis, particularly for reactivation from latently infected trigeminal ganglia in animal models [ 6869 ]. This feature has likely minimized herpes development of TK based resistance in the immunocompetent community. The most frequent verificaion reactivated after an episode caused by a resistant HSV strain are thus ACV-sensitive [ 70 ]. Therefore, despite an initial antiviral efficacy, the same resistance will likely be selected as the previous episode and ACV vsrification may fail, especially if the immunosuppression condition remained.
Laboratory confirmation of clinically suspected genital herps diagnosis is necessary. In addition verificatiln helping the therapeutic management of ulcerative genital lesions and herpes diagnosis, it helps identify persons at risk of transmitting infection.
Herpes diagnosis is recommended and validated molecular assays are a good alternative to cell culture.
Indirect diagnosis should use only FDA or CE approved type-specific serology based on glycoprotein G1 and G2 antigens and has to be considered for recurrent genital symptoms or atypical symptoms without laboratory confirmation and for testing pregnant women at risk of acquiring HSV infection.

Virus detection and quantification by molecular biology Molecular biology has emerged for the last ten years as an attractive potent method to detect and possibly quantify HSV DNA. Indirect serological diagnosis of herpetic infections Detection of HSV-specific IgG antibodies can be done sensitively by several immunological methods.

History of recurrent or atypical genital disease with direct virus detection negative HSV-1 antibodies do not differentiate between genital and oropharyngeal infection.
Herpes genital herpes Differentiation between primary and established infection guides counseling and management. At the onset of symptoms, the absence of HSV IgG against the virus type detected in the genital lesion is consistent with a primary infection. Seroconversion should be demonstrated at follow-up. Partner with genital herpes Knowledge of infection status can guide patient education and counseling if the partnership is discordant. Pregnant women Not routinely recommended.
HIV infected patients Not routinely recommended. As the evidence is not consistent, testing of HIV-positive pregnant women is not routinely recommended.
Therapeutic monitoring: drug verification testing Long-term prophylaxis and treatment with antiviral drugs targeting the viral DNA polymerase DNA pol can result in the development of resistance [ 60 ].
