You Need to Wait for an STD Blood Evaluation

July 20, 2018

Learning that you were subjected to a sexually transmitted disease (STD) such as herpes or HIV can be terrifying. It isn’t important whether a former sexual partner calls to inform you they are infected or you listen in the health department you will need to get tested. It is scary to learn that you might be in danger.​

Although it’s possible to check for some STDs, such as chlamydia and gonorrhea, relatively quickly after disease using a highly sensitive urine evaluation, this isn’t the case with all STDs.

Any STD test that finds an illness using antibodies can not be used for at least fourteen days. It may be six months or more before you may trust a negative result. The unfortunate truth is that STD effects take time. 

Why You Have To Wait

Many STD tests, particularly those for viral STDs like herpes and HIV, don’t look for the disease itself. Instead, they search for your body’s response into the infection, specifically your antibody response.

When you’re exposed to or infected with an STD, your immune system will try to fight the pathogen. Part of this procedure entails making antibodies against the infectious agent. These antibodies are specific to whatever you are infected with. That is how a blood test can search for antibodies to a particular STD and inform whether you have it. Nonetheless, these particular antibodies take time to develop.

Just how Long it takes for one to create detectable amounts of antibodies from the disease depends upon a number of factors, including:

  • Whether you’ve been infected with the same pathogen until
  • How busy the disease is
  • How much of the pathogen entered your own body
  • The overall health of your immune system
  • what sort of antibody the evaluation is looking for

How Long Does an STD Blood Test Require?

The soonest a test may have a reasonable prospect of detecting an antibody response is two weeks.

That’s only true for tests that look for a specific early kind of antibody known as IgM. Many antibody tests look for IgG, which requires more time to develop. Additional even an IgM test cannot be counted on to be true at this early point after infection.

Over the first couple of months, there’s a very high risk of false negative test results. This risk goes down over time. By six months after disease, most people will turn positive within an antibody test.

As a result of this, antibody testing is not suitable for people who are worried they might have been very recently exposed to HIV or herpes. If that is the case, talk to your doctor about which kind of testing might be perfect for you.

As soon as you get a evaluation, the turnaround time for test results also varies. Some rapid STD tests may give results in a hour. Additional STD results take up to 1-2 weeks to come in. This varies both by what test is utilized along with what facilities your physician’s office has. Some doctors will need to send out blood and urine samples to be analyzed. Others can conduct the tests inside. These factors can have a significant effect on STD effects time. 

What Do You Need to Do If You Can’t Wait?

If you’ve got a known, current exposure to HIV, special testing may be accessible.

These acute tests are made to detect a new disease. But, not all doctors are going to have access to these tests. They may need to send you to some more specialized clinic or laboratory.

If you think you’re exposed to herpes and you have symptoms, visit your doctor when symptoms arise. Antibody tests take some time to become accurate. If your health care provider can perform a viral culture on your sores, you are able to get results a lot sooner.  For this viral culture to work, your doctor needs to be able to isolate the active virus from your sores. There’s only a brief window when that’s possible after the beginning of an outbreak.

If you’re tested after your nausea have started to heal, there’s a possibility of a false negative test. However, your doctor might be able to give you a presumptive diagnosis based upon the appearance of your outbreak.
