STD Testing

Complete STD Testing

Sexually transmitted disease (STD) testing is a topic that every person who is sexually active should understand thoroughly, since it is essential to maintaining sexual health, as well as overall health and well-being. Fact is, 20 million people in the United States are newly infected with STDs every year, according to the CDC, so knowing when to get tested and what tests you should be having is simply smart health management. So what do you need to know about medically sound STD testing? Here are some of the questions people frequently ask as they work to become well-informed about STDs, tests and their sexual health. View sample STD test results with lab variations, ranges and explanations.

Which STD to get tested for?

A specific answer to that question depends largely on your personal sexual behavior and risk factors. That said, most doctors will recommend testing for the most common STDs. These are Chlamydia, Gonorrhea, HIV, Herpes (Types 1 and 2), Syphilis, and Trichomoniasis. Depending upon your personal circumstances, getting screened for all of these may not be necessary, or there may be other tests that you should have, such as testing for less common STDs like hepatitis A, B, and/or C, or Human T-Cell Lymphotropic Virus (HTLV).

STD Treatment and Counseling

When ordering an STD package or individual test from Health Testing Centers that tests for chlamydia, gonorrhea, trichomoniasis, or HSV type 2, a physician consultation and treatment are included when there is a positive result. If you test positive for any of the 4 mentioned STD's, a telephone or video consultation will be provided at no additional cost by one of our third party physicians. The physician from PWN Health will contact you within 4 to 24 hours of receiving your test result. At the end of the consultation the physician may prescribe the necessary medication for treatment. It is up to the sole discretion of the physician to provide any medical treatment based on test results and any medical information they received during the consultation. Cost of the prescription is not included.

When should STD tests be done?

Perhaps the most important thing to know about when to get tested for STDs is that you should not wait for symptoms to appear. That's because a number of sexually transmitted infections can be present in your body without presenting any symptoms at all, and others may produce non-specific symptoms that mimic those of minor ailments, like a common cold or flu. That means that looking and feeling perfectly healthy is no guarantee that you – or a sexual partner – have not contracted an STD.

If you have had unprotected sex, have become aware that a partner may have an STD, or have symptoms that cause concern, recommended test times are 2-3 weeks after the sexual encounter or exposure for initial testing, then you should be screened again after 3 months. Early testing can detect infections that develop fairly quickly, like Chlamydia and gonorrhea, for instance, while late testing is important for STDs that develop more slowly, such as HIV. Other important times to be tested are:

  • At the start of new a relationshipSTD test technician reviews samples
  • If you or a partner are sexually active with more than one person
  • When you and your partner are considering sex without condoms
  • If you are pregnant or planning to start a family

Lastly, every individual who is sexually active should have complete STD screening done periodically. Just how often you should be screened depends upon your personal risk factors, so working out an appropriate testing schedule for your needs is best done by discussing those factors with a healthcare and/or medical testing professional.

Do they test for STDs during a Pap smear?

Many people are under the impression that their doctors test for STDs during Pap smear appointments. However, the purpose of these exams is to look for changes that indicate a risk for developing cervical cancer. Since many cases of cervical cancer can be linked to Human papilloma virus (HPV), a sexually transmitted infection, doctors will often look for physical signs of HPV while performing these exams. Comprehensive STD screening tests, which look for a variety of common STDs that all sexually active individuals should be screened for, are not typically done at these appointments, and most STDS will not show on a standard Pap test.

It is also important for the person who cares about their sexual health to know that STD screening is not standard practice during annual pelvic exams or yearly physical exams. Typically, patients will not be screened for STDs unless they request a doctor test for these infections.

What STD will show up in a blood test?

Blood tests can be used to test STD status for a number of infection types. STDs that show up in a blood test include:

  • HIV
  • Syphilis
  • Herpes, Types 1 and 2
  • Hepatitis A, B, and C
  • HTLV

Urine tests are typically used to detect the following STDs:

  • Gonorrhea
  • Chlamydia
  • Trichomoniasis

Some doctors also use swabs to collect samples of bodily fluids for testing, a practice that has become less common as accurate blood and urine tests have become available.

What do they test for in a STD test?

Whether testing is done via blood or urine samples, the lab that processes those samples is looking for key indicators of STD infection. For bacterial infections, such as gonorrhea, syphilis or Chlamydia, those indicators would be bacteria in urine samples. In blood tests, technicians would look for antibodies that the body produces to fight bacteria associated with infection. In cases of viral STDs, such as HIV, HTLV, HPV, hepatitis or herpes, labs look for antibodies the immune system makes to attack the invading viruses. Trichomoniasis is an infection caused by parasites, which will be found in the urine of infected individuals.

Now that we've gone over some basics on how to test infections, here is an important note on what to do if your test yields a positive result. If you are found to be infected with one or more STDs, your first step – on the day those test results come in – is to seek treatment. This is essential to minimizing the short-term effects of STDs and avoiding more serious potential long-term effects, such as infertility, cancer, organ damage and blindness, to name just a few. Your second step is to inform any past or current sexual partners that may also be infected, so that they too can seek treatment. Additionally, it is important to abstain from all sexual activity until treatment is complete to avoid spreading the infection.
