It's recommended for people between 13 and 64 to be tested for HIV at least once as part of routine health care.

Patient Registration Form



Client Assessment Questionnaire

There's not a single test for all STIs - each STI has its own test. Our healthcare providers determine which tests you need based on your sex history and or needle sharing practices. Clear and honest communication with your provider is encouraged for proper testing. STI testing may include:

  • A urine test - you just pee into a cup.
  • A blood test - a nurse takes blood from your arm or does a quick finger stick.
  • A physical exam - a healthcare provider looks at your skin, throat, rectal, and genital area to check for warts, sores, rashes, irritation, or discharge. Each exam may be different, and you may be asked to undress for the physical exam.
  • Testing your sores – based on your conversation with your health care provider, they may take a sample of fluid from any sores or blisters you have with a swab. They may use a swab to gently take discharge or cell samples from your penis, vagina, urethra, cervix, anus, mouth or throat. For some patients who are not experiencing symptoms of STI or contact to a partner with a STI, you may be eligible for a Quick Check appointment, where you collect your own swabs.

You can get tested for most STIs whether you have any symptoms or not. Some STIs look and act alike, so you might be tested for a few different infections. Our healthcare providers may be able to tell right away if you have an STI, but most tests take seven (7) days to come back from a lab.
 

No, we limit examination space to the patient and the provider and or nurse. This ensures patients have a safe and confidential visit.

The clinic offers pre-exposure prophylaxis (PrEP) education and referrals for HIV negative persons who men who have sex with men, transgender women, bisexual, those who share drug equipment or any other person interested in preventing HIV infection. PrEP medical services are available for uninsured persons; however, if you have insurance, our staff can help you find a provider with your insurance carrier. 

PEP, or post-exposure prophylaxis, is a combination of medications that an HIV-negative person takes for 28 days AFTER a possible exposure to HIV. PEP is more effective the sooner it’s started and must be started within 72 hours of the exposure.


Doxy PEP is very effective way of preventing STDs. Your health provider can prescribe an antibiotic called doxycycline for you to take soon after you have sex. It decreases your chances of catching gonorrhea, chlamydia and syphilis from your sex partner by 50-80%. Talk to your medical provider if you’re interested in trying doxyPEP. 

Our HIV Partner Services (PS) is a free, voluntary, and confidential (anonymous) service that can help let an individual's sex and/or needle sharing partner(s) know they have been exposed to HIV/AIDS.  

PS can be done three (3) ways:  

  1.  The Health Department can notify your partner(s) for you anonymously; or
  2. You can get coaching to tell your partner(s) yourself; or
  3. You can have a trained counselor present to support you while you have the conversation with your partner(s).



For more information or help with HIV Partner Services, call (714) 834-7748.
 

Sharps is a medical term for devices with sharp points or edges that can puncture or cut skin. Examples of sharps include:

  • Needles – hollow needles used to inject drugs (medication) under the skin
  • Syringes – devices used to inject medication into or withdraw fluid from the body
  • Lancets, also called “fingerstick” devices – instruments with a short, two-edged blade used to get drops of blood for testing. Lancets are commonly used in the treatment of diabetes.
  • Auto Injectors, including epinephrine and insulin pens – syringes pre-filled with fluid medication designed to be self-injected into the body

If you are accidently stuck or shared a needle with another person's used needle or other sharps:

  1. Wash the exposed area right away with water and soap or use a skin disinfectant (antiseptic) such as rubbing alcohol or hand sanitizer.
  2. Seek immediate medical attention by calling your physician or local hospital.

Follow these same instructions if you get blood or other bodily fluids in your eyes, nose, mouth, or on your skin.
