The results of this test needs to be confirmed by additional tests like other HIV screening tests. For carrying out the test the finger strip is cleaned with alcohol. Then it is pricked with a lancet to get a drop of blood. In such a way the specimen of the blood is collected and transferred to a vial. It is mixed with a developing solution. The test apparatus is then placed in the vial. The results of the test can be read within 20 minutes.

False positive results - Even though none were found in clinical trial, a analysis( statistical) of the data shows that a very less number of people who are not infected with HIV-1 will have reactive test results.
