A western blot can also be used as a confirmatory test for Hepatitis B infection and HSV-2 (Herpes Type 2) infection. [ 14 ] [ 15 ] In veterinary medicine, a western blot is sometimes used to confirm FIV + status in cats.
With confirmatory Western blot, the chance of a false-positive identification in a low-prevalence setting is about 1 in 250 000 (95% CI, 1 in 173 000 to 1 in 379 000). The specificity rate given here for the inexpensive enzyme immunoassay screening tests indicates that, in 1,000 HIV test results of healthy individuals, about 15 of these results ...
The herpesvirus glycoprotein B is a type-1 transmembrane protein with a signal sequence at its N terminus. [2] The crystal structure of herpes simplex virus (HSV) type-1 and Epstein–Barr virus glycoprotein B ectodomains were solved as a trimer, revealing five structural domains (I-V).
Herpes simplex virus 1 (cold sores) and 2 (genital herpes) (HSV-1 and HSV-2) are two members of the human Herpesviridae family, a set of viruses that produce viral infections in the majority of humans. [1] [2] Both HSV-1 and HSV-2 are very common and contagious. They can be spread when an infected person begins shedding the virus.
Sequencing is the only diagnostic method that will provide the full sequence of a virus genome. Hence, it provides the most information about very small differences between two viruses that would look the same using other diagnostic tests. Currently it is only used when this depth of information is required.
Herpetic gingivostomatitis is an infection caused by the herpes simplex virus (HSV). The HSV is a double-stranded DNA virus categorised into two types; HSV-1 and HSV-2.HSV-1 is predominantly responsible for oral, facial and ocular infections whereas HSV-2 is responsible for most genital and cutaneous lower herpetic lesions.

Dried blood spot testing for HIV is not considered sensitive enough for diagnostic testing, but may be useful in estimating the prevalence of HIV through surveillance. DBS specimens also pose less of a biohazard risk to handlers, and are easier to transport or store than liquid blood specimens.
