STI Testing: Should I Get Tested for a Sexually Transmitted Infection?

You may want to have a say in this decision, or you may simply want to follow your doctor's recommendation. Either way, this information will help you understand what your choices are so that you can talk to your doctor about them.

STI Testing: Should I Get Tested for a Sexually Transmitted Infection?

Get the facts

Your options

  • Have a blood or urine test or some other test to screen for sexually transmitted infections.
  • Don't have the test.

This choice isn't for you if you believe you've been exposed to an STI or you have symptoms of an STI. You need to have a test as soon as possible.

This topic doesn't cover decisions about testing for HIV or testing for hepatitis B and C. For more information see:HIV Testing: Should I Get Tested for Human Immunodeficiency Virus?andHepatitis B and C: Should I Be Tested?

Key points to remember

  • Many health professionals recommend having a routine screening test for certain STIs if you have a high risk for infection. For example, you're at high risk if you're younger than 25 and sexually active, or if you've had more than one partner in the past year. Some STI tests are recommended for pregnant women whether or not they have a high risk for infection.
  • Some STIs don't cause symptoms, or they can cause symptoms that go away. So unless you have a test, you may not know that you have an STI.
  • STI testing can help find an infection early. If you know that you have an infection, you can get treatment and prevent spreading the infection to others.
  • Left untreated, some STIs can lead to serious problems. For example, if a woman has an STI when she gives birth, her newborn may have the disease.
  • If your test shows that you have an STI, your sex partner(s) will need to know so they can be tested.
  • Some STIs can be cured with treatment. Others can't be cured, but treatment can help with symptoms.
  • You may not need to be tested if you aren't sexually active, you have a very low risk for infection, or you and your doctor have already discussed whether you need a test.
FAQs

What is an STI?

Sexually transmitted infections are diseases spread by sexual contact. Some of the most common STIs are:

Left untreated, some STIs can lead to serious problems. For example:

  • Certain high-risk types of HPV can cause cervical cancer in women, penile cancer in men, and rectal and oral cancer in men and women.
  • Some STIs can be passed from a woman to her newborn, which can cause serious problems for the baby.
  • Chlamydia and gonorrhea can cause pelvic inflammatory disease (PID) in women. PID can lead to serious problems, including not being able to have a baby (infertility).
  • Syphilis can cause problems with pregnancy, nerve and heart problems, and death.
  • Gonorrhea can increase the risk of bladder cancer in men.

How are STIs treated?

Treatment is available for all sexually transmitted infections (STIs) to relieve symptoms, even if a cure isn't possible.

Some of the most common STIs—chlamydia, gonorrhea, and syphilis—are caused by bacteria and are treated and cured with antibiotics.

STIs caused by viruses, such as genital herpes and genital warts, aren't cured with antibiotics. But treatments are available to relieve symptoms.

What STI tests do experts recommend be done routinely?

Having a routine STI test means getting tested even though you don't have symptoms of an infection. Experts say that certain groups should be routinely tested for certain STIs. Some expert opinions may vary, and your doctor may recommend testing based on your personal history.

Chlamydia

The U.S. Preventive Services Task Force (USPSTF) recommends a chlamydia test for all nonpregnant and pregnant women ages 24 and younger. They also recommend testing for women older than 24 with high-risk sexual behaviors.footnote 2

The Center for Disease Control (CDC) recommends that men who have sex with men also have testing.footnote 1

You have a high risk of getting chlamydia if:

  • You're a sexually active female who is younger than age 25.
  • You've had chlamydia or other STIs before.
  • You:
    • Have a new sex partner.
    • Have had more than one sex partner in the past year.
    • Have a high-risk partner. A high-risk partner is someone who has other sex partners, unprotected sex, or has an STI.
  • You don't use condoms when having sex, you use drugs, or you exchange sex for money.
Gonorrhea

The USPSTF recommends a gonorrhea test for all nonpregnant and pregnant women ages 24 and younger. They also recommend testing for women older than 24 with high-risk sexual behaviors.footnote 2.

The CDC recommends that men who have sex with men also have testing.footnote 1

You have a high risk of getting gonorrhea if:

  • You're a sexually active male or female younger than 25.
  • You have had gonorrhea or other STIs before.
  • You:
    • Have a new sex partner.
    • Have had more than one sex partner in the past year.
    • Have a high-risk partner. A high-risk partner is someone who has other sex partners, unprotected sex, or has an STI.
  • You don't use condoms when having sex, you use drugs, or you exchange sex for money.
Syphilis

The USPSTF recommends a syphilis test for all men and women at high risk and all pregnant women.footnote 4, footnote 3

You have a high risk of getting syphilis if you:

  • Are a man who has sex with men and has high-risk sexual behaviors.
  • Are a sex worker or you exchange sex for drugs.
  • Are in an adult prison or jail.

What are the tests for STIs?

Tests for STIs are fairly simple. If you have a test for chlamydia or gonorrhea, a nurse or doctor will test for bacteria that cause the infections. You may have a urine test, or the doctor may take a sample of body fluid from the throat, inside the tip of the penis, or inside the rectum or vagina. A gonorrhea culture test also may be done to see if the bacteria are resistant to antibiotics.

A syphilis test looks for antibodies to the bacteria that cause syphilis. Your doctor may do a blood test or may test body fluid or tissue. A follow-up test may be done to confirm the infection.

What are the benefits of getting tested?

Getting tested can help find an infection early or when you have no symptoms. This is important so that:

  • You can get treatment and avoid long-term problems, such as not being able to have a baby (infertility).
  • If you know that you have an STI, you can get treatment and avoid spreading the infection to others.
  • If you know that you have an STI, you can tell your sex partner(s) so they can be treated and can avoid spreading the infection.
  • If you're pregnant, an STI test can find an infection so you don't spread the infection to your newborn.

What are the risks of getting tested?

  • If your test shows that you have an STI, your sex partner(s) will need to know and get tested, which may affect your relationship.
  • If you have an STI, your doctor may be required by law to report it to your local health department. You may be asked for names and addresses of your sex partners.
  • You could have a false-positive test result, which shows that you have the disease when you actually don't. This could cause you unneeded worry and treatment.
  • For syphilis, you could have a false-negative result, which shows that you don't have the disease when you actually do. (Sometimes the test can't find the antibodies yet.) So you might infect others because you don't think you have the disease.

Why might your doctor recommend that you get tested?

Your doctor may want you to be tested if:

  • You have a high risk for getting an STI.
  • You are pregnant.

Personal stories about considering STI testing

These stories are based on information gathered from health professionals and consumers. They may be helpful as you make important health decisions.

I just broke up with my partner. I thought we were in a monogamous relationship. But then I found out he was having sex with other people while we were together. I have an appointment to get tested right away. I don't want to risk giving an infection to someone else.

Jason, age 20

I'm a newlywed and just found out I'm pregnant! My doctor says I'll need to have an STI test, and I think that's crazy because I know my husband is faithful to me. But my doctor said all pregnant women should be tested, so I'm going to do it. I want to make sure that I have a healthy pregnancy and a healthy baby.

Serena, age 23

I had a test several months ago, and it was negative. I haven't had symptoms of any STIs since. I'm not in a relationship, and I haven't had sex with anyone since the test, so I don't think a test is necessary for me now.

Heather, age 30

I don't plan to have a test now. My doctor says I'm at pretty low risk since I haven't had sex with anyone since my wife and I split up a few years ago. But if I meet someone, I may do it and ask her to do the same. I think it would be a pretty hard conversation to have, though.

Bob, age 45

Check the facts

1. If I don't have any symptoms of an STI, I don't need a test.

  • True
  • False
  • I'm not sure
That's right. Some STIs don't cause symptoms, especially in women. Experts recommend that sexually active women who are younger than 25, as well as others at high risk, have routine STI testing.

2. If I'm a woman and don't know if I have an infection, I could spread it to others and develop serious problems if I don't get treatment.

  • True
  • False
  • I'm not sure
Yes, that's right. Untreated STIs can lead to serious problems in women, including pelvic inflammatory disease and infertility. A pregnant woman also can pass the infection to her newborn.

3. If I'm younger than 25, I need an STI test, because everyone that age has a high risk for getting an STI.

  • True
  • False
  • I'm not sure
Yes, you're right. People younger than 25 have a higher risk of getting an STI if they are sexually active. If you've never had sex or have discussed your risk with your doctor, you may not need a test.
