What is an HIV Test and When Is It Prescribed?

HIV is one of the most common sexually transmitted infections. It affects a significant part of the world’s population and is among the major health concerns. When left untreated for a longer period, it may lead to AIDS (acquired immunodeficiency syndrome), which is the most advanced stage. This infection spreads when a healthy person comes into direct contact with the bodily fluids (blood, semen, pre-seminal fluid, rectal fluids, vaginal fluids, and breast milk) of an infected person. Apart from this, it can also be transmitted from an infected mother to her child during pregnancy, childbirth, or breastfeeding.

Early detection is the best way to control HIV infection and prevent its progression to AIDS. Booking an HIV test in a timely manner can help manage the symptoms in the initial stages. 

What is an HIV test?

It is a blood test that detects the presence of HIV (human immunodeficiency virus) in an individual’s blood. The human immunodeficiency virus attacks the cells of an individual’s immune system, destroying them over time. The main function of these cells is to protect the body against a number of bacteria and viruses. However, when a person’s body loses a large quantity of these cells, its ability to fight off other infections reduces significantly.

When Does a Doctor Prescribe an HIV Test?

An HIV test is useful in finding out if an individual has been infected with HIV. Usually, doctors suggest it to individuals who display any symptoms of this infection.

Here are a few common warning signs:

  •      Unexplained weight loss
  •      Excessive sweating during the night
  •      Persistent fever
  •      Constant lethargy
  •      Swollen lymph nodes
  •      White spots in the mouth or throat
  •      Severe diarrhoea
  •      Rashes on skin or in the mouth

·       Difficulty in remembering things


However, many people do not develop any symptoms in the initial stage of HIV infection. This is the reason it can remain undetected for longer periods. So, this test may be done as a routine test as part of preventive healthcare.

There are several NABL-accredited diagnostic labs that offer HIV screening, as well as other STD tests, at a reasonable price. Most of them also offer the facility of hassle-free online booking.
