The rapid test is recommended for pregnant women or women who want to become pregnant, since there are now treatments for the baby to be born healthyRapid tests for detecting HIV are over 98 percent effective. The probabilities of showing positive results are higher in the population that was exposed to a higher risk of contracting the disease, such as having had sex between men or without using a condom, or the use of syringes used to inject drugs or tattoos, said Dr. Luz Alicia Gonzalez Hernandez, head of the HIV Unit of the Civil Hospital “Fray Antonio Alcalde”.

She explained that the test is not diagnostic, so it is always necessary to corroborate results through a confirmatory test, especially in those who do not remember having had risky practices, since patients with liver or autoimmunity problems usually have false positive results.

There are two types of rapid tests: one is to detect the virus through saliva or through a blood sample obtained by a finger prick. The body fluid obtained is placed in a plastic tablet. A test strip will show two red lines if the result is positive and one red line if it is negative. If it does not mark anything, it means that it is defective and apply another test.

There are also rapid screening tests. They are so called because they are able to give a result within 30 minutes. They can be performed on different body fluids, such as blood, serum, plasma and oral fluid.

A negative result in a screening test excludes HIV infection, unless the exposure to HIV has been recent. Depending on the characteristics of the screening techniques, HIV infection is considered to be absent after a risk exposure if the ELISA is negative at 2-4 weeks (in the case of fourth-generation tests) or at three months (in the case of third-generation tests or post-exposure precautions).

No, it is important to mention that the test is voluntary, no one is obliged to undergo it, nor to declare that he/she lives with HIV or AIDS. It should not be a requirement to receive medical care, obtain employment, get married, be part of educational institutions or have access to any service.

Reactive (Positive): Means that HIV antibodies were found in the blood sample, indicating that the person may be infected. Any positive result needs to be checked with a confirmatory test called a Western Blot. Being HIV positive does not mean that you have AIDS, nor does it mean that you are at risk of near death if you follow the proper treatment. If you test positive, you will receive professional emotional support during the counseling service to help you adjust to your new situation.

Non-Reactive (Negative): Means that no HIV antibodies were found in the sample, indicating that the person is not infected. Even if the result is negative or “false negative” it is important to take preventive measures to avoid contracting the virus.

The HIV test determines if a person has HIV. The human immunodeficiency virus (HIV) is the cause of acquired immunodeficiency syndrome (AIDS). AIDS is the most advanced stage of HIV infection.

A negative HIV test result shows that you do not have HIV.  Continue to take steps to avoid HIV infection, for example, use condoms during sex and, if you are at high risk for HIV infection, take medication to prevent it (this is called pre-exposure prophylaxis, or PrEP).

The Centers for Disease Control and Prevention (CDC) also recommends that all pregnant women be tested for HIV so that they can start taking HIV medications if they are HIV-positive. Women with HIV take HIV medications during pregnancy and childbirth to reduce the risk of mother-to-child transmission of HIV and to protect their own health. For additional information, read HIVinfo’s fact sheet on Preventing Perinatal HIV Transmission.
