Can you test negative for herpes and still have it?

Can you test negative for herpes and still have it?

A “negative” viral culture or PCR result could mean you don’t have genital herpes. But in some cases, a person could still have genital herpes and a negative result. That’s likely due to other factors related to how much virus there is in the sores. You don’t need to do anything to prepare for these tests.

What can mimic herpes symptoms?

Noninfectious conditions that can mimic genital herpes include Reiter syndrome, contact dermatitis, Crohn disease, Behçet syndrome, trauma, erythema multiforme, and lichen planus.

How often is herpes misdiagnosed?

Turns out herpes is misdiagnosed 20% of the time, with professionals mistaking everything from fungal and yeast infections to other skin conditions for the STD. The tests themselves are also inaccurate; failing to detect up to 25% of “true positive” cases.

Will herpes show up in a standard blood test?

Blood tests can be used when a person has no visible symptoms but has concerns about having herpes. Blood tests do not actually detect the virus; instead, they look for antibodies (the body’s immune response) in the blood.

Can herpes be dormant and not show up in a blood test?

If you have the herpes virus and your body has produced antibodies, it can be detected on a blood test, even if you have no symptoms. The only time the virus might not be detected on a test (after you’ve contracted it) is if you’ve been tested too early.

What test is most accurate for herpes?

PCR test: The PCR test can tell if you have genital herpes even if you don’t have symptoms. The PCR test looks for pieces of the virus’s DNA in a sample taken from cells or fluids from a genital sore or the urinary tract. This is a commonly used test to diagnose genital herpes and is very accurate.

Can you detect herpes while dormant?

But because of HSV dormancy, among other reasons, not many people can pinpoint the moment they contracted the virus. Transmission is common from contact with a partner who might not know they have HSV and isn’t showing symptoms of infection.
