Can you be tested for genital herpes even if you dont enjoy symptoms?

quite a few friends of mine sleep next to the same individual and found out she had genital herpes. Now they are adjectives going to get tested. Will they be capable of find out if they have it through a blood audition?Can you be tested for genital herpes even if you dont enjoy symptoms?
Yes you can but it is hard as you can gain false negative and false positives, if they hold contracted herpes type2 they will soon know about it, you can rest assurred some except all will enjoy caught it, even if she was not infectious at time..
There is a blood experiment for herpes, it is a herpes zoster antibody test.
A ample number of people who own herpes are asymptomatic. See links.
You can get blood test for herpes simplex, and some of them will distinguish between HSV type 1 and type 2.
However, you can't always inform from the test whether the infection is on the genitals or on the mouth (cold sores). You can acquire either virus on any site, although the majority of HSV1 infections are mouth and HSV2 are genital.
If you do test, be prepared for most of you to come positive for HSV1. Most culture carry this virus whether they know it or not. It may or may not indicate a genital infection.
Generally speaking, the blood test raise more question than they answer, and I wouldn't recommend them as a screening test.
YES YOU CAN DO A BLOOD TEST!!
Yes, you can check for antibodies in the blood but it is expensive. Why verbs about it? If you don't hold symptoms, you don't have problems...
