Dear pimpcess327,

HIV tests detect antibodies — the immune system's response to infection. For the majority of people, HIV testing will be accurate at four to six weeks after possible infection. However, for some people it may take longer — up to three months — for detectable antibodies to develop. This is called the "window period." During the window period, HIV tests can come back negative even though the person has the virus. HIV can be passed to other people during the window period.

To make an appointment for HIV testing, call 1-800-230-PLAN to find a Planned Parenthood health center nearest you. Tests are also available from most health care providers, hospitals, and health centers. Local, state, and federal health departments may offer free testing. The Centers for Disease Control and Prevention has a website that lists HIV testing locations and offers information about home testing. The site can also be accessed in Spanish.

Hope this information helps!

Take care,
