STD Testing: What’s Right for You?
Sexually Transmitted Diseases (STDs) are common, but the types of STD testing you need may vary by your risk factors. Find out what’s recommended for you.
If you’re sexually active, particularly with multiple partners, you’ve probably heard the following advice many times: Use protection and make sure you get tested. This is important because people can have a sexually transmitted disease (STD) without knowing it. In many cases, no signs or symptoms occur.
But what types of STD testing do you need? And how often should you be screened? The answers depend on your age, your sexual behaviors and other risk factors.
If you’re a woman, don’t assume that you’re receiving STD testing every time you have a gynecologic exam or Pap test. Regardless of your gender and age, if you think you need STD testing, request it from your provider. Talk to your provider about your concerns, and mention specifically what infections you think you might have.
Gonorrhea and Chlamydia
These STD’s often co-exist in the same infected individual and can be passed simultaneously to a sexual partner. Since treatment for each of these conditions may differ, it is excellent medical practice to test for both if either one is suspected. Furthermore, these serious STD’s may not cause any symptoms at first. Later, if they are not treated, they can cause pain and serious health problems, such as arthritis and infertility.
Get screened annually if:
- You’re a sexually active girl or woman under age 25
- You’re a woman older than 25 and at risk of STDs — for example, if you’re having sex with a new partner or multiple partners
- You’re a man who has sex with men
Chlamydia and gonorrhea screening is done either through a urine test or through a swab inside the penis in men or from the cervix in women. The sample is then analyzed in a laboratory. Screening is important, because if you don’t have signs or symptoms, you can be unaware that you have either infection.
HIV-1 Infection and AIDS
HIV is the abbreviation used for the human immunodeficiency virus. HIV is the virus that causes AIDS (acquired immunodeficiency syndrome), a life-threatening disease. The Centers for Disease Control and Prevention (CDC) encourages HIV testing, at least once, as a routing part of medical care if you’re an adolescent or adult between the ages of 13 and 64. The CDC advises yearly HIV testing if you are at high risk of infection.
Syphilis is a serious bacterial infection. It is usually passed from one person to another by sexual contact. If it is not treated, syphilis can lead to permanent brain, nerve, and tissue damage.
Hepatitis B is a viral infection of the liver. The liver becomes inflamed and tender. It may also become swollen. Areas of liver tissue may be destroyed by the inflammation. Hepatitis B is a serious, sometimes severe and even fatal type of hepatitis. In addition to being a sexually transmit-ted disease (STD), Hepatitis B is a blood-borne pathogen and exposure to the blood of an infected person may result in infection.
Hepatitis C is a viral infection of the liver. The liver becomes inflamed. Hepatitis C is caused by the hepatitis C virus. The virus is spread mainly through contact with infected blood. Sometimes it is spread through sexual contact.
Request testing for HIV, syphilis, and hepatitis if you:
- Test positive for gonorrhea or chlamydia, which puts you at greater risk of other STDs
- Have had more than one sexual partner since your last test
- Use intravenous (IV) drugs
- Are a man who has sex with men
Your doctor tests you for syphilis by taking either a blood sample or a swab from any genital sores you might have. The sample is examined in a laboratory. A blood sample is taken to test for HIV and hepatitis.
Genital herpes is a common STD caused by a virus. The virus is called the herpes simplex virus, or HSV. It causes painful blisters that break open and form sores in the genital area.
No good screening test exists for herpes, a viral infection that can be transmitted even when an infected person doesn’t have symptoms. Your doctor may take a tissue scraping or culture of blisters or early ulcers, if you have them, for examination in a laboratory. But a negative test doesn’t rule out herpes as a cause for genital ulcerations.
A blood test also may help detect a herpes infection, but results aren’t always conclusive.
Some blood tests can help differentiate between the two main types of the herpes virus. Type 1 is the virus that more typically causes cold sores, although it can also cause genital sores. Type 2 is the virus that more typically causes genital sores. Still, the results may not be totally clear, depending on the sensitivity of the test and the stage of the infection. False-positive and false-negative results are possible.
HPV – Human Papillomavirus
Certain types of human papillomavirus (HPV) can cause cervical cancer while other varieties of HPV can cause genital warts. Most sexually active people become infected with HPV at some point in their lives, but never develop symptoms. The virus typically disappears within two years.
No HPV screening test is available for men, in whom the infection is diagnosed only by visual inspection or biopsy of genital warts. In women, HPV testing involves:
- Pap test. Pap tests, which check the cervix for abnormal cells, are recommended every two years for women between ages 21 and 30. Women age 30 and older can wait three years between Pap tests if their past three tests have been normal.
- HPV test. Samples for the HPV test are collected from the cervical canal. This test usually isn’t offered to women younger than 30 because HPV infections that will ultimately clear up on their own are so common in this age group.
HPV has also been linked to cancer of the vulva, vagina, penis and anus. Vaccines can protect both men and women from some types of HPV, but they are most effective when administered before sexual activity begins. Western Wayne Medical offers Pap test, HPV test, and Gardasil vaccine for diagnosis and prevention of HPV.
