Thank you for reaching out with your question. I understand this must be confusing for you.nnHere's what might be happening:nn**About Herpes Testing:**nThe tests for herpes typically look for antibodies (your body's immune response) to the virus, not the virus itself. There are a few reasons why you might get a negative result even though you've had genital herpes for 20 years:nn1. **Test Type Matters**: Some tests are more accurate than others. The type-specific IgG blood test is the most reliable for detecting HSV-1 and HSV-2 antibodies.nn2. **Antibody Levels Can Fluctuate**: In some rare cases, antibody levels can decrease over time, especially if you haven't had an outbreak in many years, potentially leading to a false negative.nn3. **Testing Error**: Lab errors, though uncommon, can occur.nn4. **Initial Diagnosis**: It's also possible (though less likely after 20 years) that the original diagnosis might have been based on symptoms rather than confirmed testing.nn**What You Should Do:**n- Discuss these results with your healthcare providern- Ask about retesting with a type-specific HSV blood testn- Consider getting tested during or right after an outbreak if you still experience them, as a swab test of the lesion can be very accuratenn**Important to Know:**nYou're correct that there's no cure for herpes—once you have it, the virus stays in your body. A negative test result doesn't necessarily mean the virus is gone.nnI strongly encourage you to follow up with your healthcare provider to discuss these results and determine the best next steps for your specific situation.
