The Human Immunodeficiency Virus (HIV) is the virus that causes Acquired Immune Deficiency Syndrome (AIDS), is transmitted by blood, vaginal secretions, semen (cum & pre-cum), and breast milk.
There are a couple of different tests for HIV. The best option is a blood test. A rapid test can also be done using either blood or a swab from the inside of the cheek. Usually, if the initial test is positive, it will be followed up with a more sensitive blood test to confirm the results.
Rapid tests take about 15–20 minutes, while a blood test sent to the lab will take up to a week for results. If HIV is contracted, it can take from three weeks to up to six months for any test to detect the virus.
