The herpes-simplex viruses, commonly known as HSV, are of two types namely the HSV-1 and HSV-2.
The Herpe- S-1, better known as HSV-, is found to be responsible for causing ulcerative lesions of lips or the oral mucosa.
In common terms, these are often called fever blisters or cold sores, while the HSV-2 is known to cause the genital herpes predominantly.
Complications caused by HSV-One
Considering the complications of these infections, the biggest problem is that they’re known to easily pass on to sexual partners via oral-genital relations.
How does it spread?
HSV-1 can easily spread by kissing, but there are many other ways for the virus to transmit. Sharing spoons, glass, fork or any other utensil can cause the HSV to spread around.
What’s more, the HSV-1 are also capable of causing sores in the genital region of the body.
Tests For HSV
More often than not, the tests for HSV1 are carried out for infections in genitals, which include the following:
Herpes viral culture – Cells from the sore are taken as sample for analysis. A cotton swab is used in this process and sample is collected in a culture cup, and hence it is known as viral culture. This test is most successful for determining genital herpes.
Herpes virus antigen detection test – In this test, the fluid comprising of infected cells from a sore are scraped off. This test is very much similar but, thereafter the only difference is that the sample is smeared onto a microscope slide, and observed to find antigens on the infected cells.
Polymerase chain reaction (PCR) test – A PCR test is performed for finding the DNA of the HSV virus. It is one of the most important distinguishing tests for HSV-1 and HSV-2.
Rather than skin sores, it is done to test spinal fluid, whenever there are any chances of an infection around the brain.
Antibody tests – Though this test is not as accurate as virus culture, blood tests can find antibodies, which can be in turn used to trace the cause of a specific sore/ulcer.
However, this test can’t really differentiate between an old and a fresh infection and the chances are high that an antibody test may not show positive results, if you’ve been very recently affected by the HSV.
Only a few blood tests can actually differentiate between HSV-1 & HSV-2.
