How common is it to misdiagnose herpes?

Meanwhile, the CDC and the US Preventive Services Task Force concur that the most widely available herpes test, called HerpeSelect, should not be used to screen asymptomatic people because of its high risk of false positives: Up to 1 in 2 positive tests could be false, according to the USPSTF’s most recent guidelines.

Is it possible to get misdiagnosed with herpes?

False positive results can occur with many diagnostic tests, including STD tests. The chances of false positive results increase as the likelihood of the infection decreases in the person being tested. False positive HSV-2 results can happen, especially in people who are at low risk for a herpes infection.

Can you test positive for herpes but it be false?

The herpes culture test (swab test) has a 0% chance of a false-positive test result. This means that a person who tests positive can be 100% sure that they have the herpes infection. The commercially available herpes IgG test (HerpeSelect) has up to a 19% probability of revealing false-positive test results.

How accurate is a herpes swab test?

Why isn’t herpes a standard STD test?

The only accurate test for herpes is a culture of an active sore or ulcer. So, if you don’t have active symptoms, you shouldn’t get tested. Herpes is spread by skin-to-skin contact. It’s highly contagious and simply not that big of a deal.

Why is herpes testing not recommended?

What is the most accurate herpes test?

PCR test: The PCR test can tell if you have genital herpes even if you don’t have symptoms.

Can you have herpes and not have any symptoms?

Some people with herpes are asymptomatic; they do not have symptoms. Women can have internal outbreaks along the vaginal barrel or on the cervix, yet it seems to them that they are symptom-free. Other people can have outbreaks and mistake them for something else, such as insect bites, razor burn, jock itch, or ingrown hair follicles.

How common is genital herpes?
