HIV 1 & 2, Ab Western Blot

The HIV 1 & 2, Ab Western Blot is a test used to detect human immunodeficiency virus (HIV) infection. In this test, a blood sample is taken and separated with an electric current. It is then transferred to a piece of blotting paper. After this, an enzyme is added to it to cause colour changes, which indicates the presence of HIV antibodies. This test is ordered for people exposed to HIV, such as those who indulge in unsafe sex, share needles or have had blood transfusions, and those with any sexually transmitted diseases.

It is a simple blood test that does not need any preparations. This test is a highly successful method used to confirm positive results acquired from other tests.
