STD : It depends on the std. Syphilis would be revealing about a month after exposure. Hiv can be detected as early as 10-14 days by measuring the HIV virus directly. Hepatitis b/c may take up to 6 months to be detected but as early as 60 days. Gonorrhea/chlamydia are not detected in the blood. Herpes is often detected incidentally given the fact primary exposure often remains unknown. ...Read more

Had general testing for stds. They didn't test for hsv2 even when i asked for the blood test, said they only test if theres sores. How come?

See a dermatologist: You certainly can get this blood test. Many are infected without knowing it. Transmission of the virus to others may occur in the absence of blisters. Most infections of hsv2 occur from contact in absence of any symptoms. Cultures reveal presence of herpes virus between attacks, even from infected people who have never had a typical lesion. Atypical symptoms are the norm. ...Read more

How accurate or reliable are on campus health clinics when it comes to blood test for stds?

How accurate or reliable are on campus health clinics when it comes to blood test for stds?

Reliable: Most health campuses have qualified practitioners on site to evaluate students. If they obtained specimen and sent it off, odds are they sent it to one of the few national labs to run the tests. This would be accurate. If unsure then, seek a second opinion. ...Read more

If I went to the hospital because I was very ill without knowing the cause and they did blood work would they usually test for an std?

If I went to the hospital because I was very ill without knowing the cause and they did blood work would they usually test for an std?

Not necessarily: This depends on the clinical picture of "very ill" The most pertinent information regarding std's is carried out with a pelvic exam. Don't forget that your medical record is YOUR record. You can get a copy of this from the hospital with a request. If you have symptoms persisting, then I would followup as an outpatient with a visit to address them. ...Read more

I've been tested (blood test) for STD and i had negative result for herpes. Does that mean i don't have either hsv1 or 2?

I've been tested (blood test) for STD and i had negative result for herpes. Does that mean i don't have either hsv1 or 2?

Probably, yes: The HSV blood tests are highly accurate, but they take up to 3-4 months to become positive. So your negative result means you aren't infected, except for a slight chance if you were exposed recently. But if you haven't been at risk for STD and no obvious contact with someone with oral herpes, you can be very sure you don't have either virus. ...Read more

I was tested via blood test for STDs and was told I tested positive for herpes exposure and that I have the antibodies in my blood but that I don t have herpes I am so confused do I have herpes ?

I was tested via blood test for STDs and was told I tested positive for herpes exposure and that I have the antibodies in my blood but that I don t have herpes I am so confused do I have herpes ?

Correlate: A pathologist's perspective: herpes simplex 1 generally affects the lips and mouth and most people are positive, simplex 2 the genitals, there's variability. The antibody tests are famously unreliable and often mistake one for the other. If you are not symptomatic, consider ignoring these results unless your physician tells you otherwise. ...Read more
