There is a home test kit for HIV and Hepatitis C available at some drugstores and online. You have to prick your finger and send the blood sample to a lab to be tested. You call the lab a few days later for results. They also provide anonymous counseling over the phone. One brand name is Home Access, and costs around $44. However, we highly recommend going to a clinic for HIV testing. Just in case you test positive it is much better to have some immediate support, like someone knowledgeable and caring to talk to about it.

So the best option, we think, is to visit your local health department or clinic for STD testing. Most clinics offer free or low-cost, confidential testing for HIV and other STDs. And they can treat you if your test comes back positive and help you reduce your risk for getting or spreading infections in the future.
