You should get tested for STIs if any of the listed risk factors apply to you:

  • A condom breaks;
  • Your partner has or has had an STI;
  • You or your partner inject street drugs;
  • You have a new sex partner;
  • You have had more than one partner in the past six months;
  • Your partner has or had sex with another person;
  • You have sex under the influence of drugs and/or alcohol; or
  • You are unable to communicate with your partner about your sexual history and ways to reduce risks.

The CDC (Centers for Disease Control and Prevention) estimates that there are more than 25 STIs (sexually transmitted infections) in existence. Listed here are the eight most common STIs in the United States.

Where can I get an HIV test?

Testing for HIV is available at Student Health Services. A fee will be charged. Call 541-737-9355 to schedule an appointment.

The tests commonly used to detect HIV infection look for antibodies produced by your body to fight HIV. Most people will develop detectable antibodies within 3 months after infection, the average being 20 days. In rare cases, it can take 6-12 months. If you are concerned that you may have HIV, please get tested again.

Free and anonymous HIV testing is available at the following Corvallis locations:

First Christian Church
602 SW Madison Ave., Room 17
Tuesdays from 1:00 to 4:00 p.m. (Enter from rear of church)

Westminster House
101 NW 23rd St.
Fridays from 10:00 a.m. to 2:00 p.m.

You need not bring anything; testing is completely free and anonymous. The results of the blood test will be available in about 20 minutes.

What is the difference between anonymous and confidential testing?
Anonymous Confidential

No personal information (such as name or Social Security number) is associated with the test result.

You receive no written documentation, but will hear what your result is from the counselor.

May be necessary if you need documentation of your HIV status, such as those entering the military or Peace Corps.

The test result becomes a part of your medical record.
