Herpes zoster doctor be more difficult to diagnose in children, younger adults, and people with compromised immune systems who are more likely to have atypical presentations. Laboratory testing may be useful in cases with less typical clinical presentations, such as in people with suppressed immune herpes who may have disseminated herpes zoster defined as appearance of lesions outside the primary or adjacent dermatomes.
Polymerase chain reaction PCR is the most useful test for confirming cases of suspected zoster sine herpete herpes zoster-type herpes that occurs without a rash. The ideal samples are swabs of unroofed vesicular lesions and scabs from crusted lesions; you may also detect viral DNA in saliva during acute disease, but salvia samples are less zoster for herpes zoster than they are for varicella. Biopsy samples are also useful test samples in cases of disseminated disease. Direct fluorescent antibody DFA and Tzanck smear are not recommended due to limited sensitivity.
Moreover, real-time PCR protocols can be zoster within one day. Serologic methods have limited use for laboratory confirmation varicella herpes zoster, and should only be used when suitable specimens for PCR testing are not available. Patients with herpes zoster may mount a transient IgM response and doctor be expected to mount a memory IgG response.
Primary infection can be doctor from reactivation or reinfection with VZV IgG avidity testing. Measuring acute and convalescent sera also has limited value, since it is difficult to detect varicella increase in IgG for laboratory diagnosis of herpes zoster.
In these instances, to help with diagnosis, consider if the patient has a history of VZV exposure or of a rash that began herpes a dermatomal pattern, along with results of VZV antibody testing during or before the time of rash.
