What is Window Period (related to HIV)?

Answer 1

In medicine, the window period for a test designed to detect a specific disease (particularly infectious disease) is the time between first infection and when the test can detect that infection. In antibody-based testing, the window period is dependent on the time taken for seroconversion.

The window period is important to epidemiology and safe sex strategies, and in blood and organ donation, because during this time, an infected person or animal cannot be detected as infected but may still be able to infect others. For this reason, the most effective disease-prevention strategies combine testing with a waiting period longer than the test's window period.

For example, the window period for HIV is usually 3 months for most people. A patient usually developes HIV antibodies 4-12 weeks after exposure, but not all. 99% of all patients will develop antibodies at 3 months. Very rarely does the window period last up to six months. These are very rare cases. HIV tests taken at the 3 month period are considered conclusive, though some patients seek a 6 month check for reassurance. If the patient is under heavy medication, such as chemotherapy, antibodies will take longer to appear.

Answer 2

Window period? Let's say a person has unprotected sex today and tomorrow the person wakes up and freaks out that they had unprotected sex, Right? This person has to wait for 3 - 6 months before they can go for the HIV test. Meaning the HIV test starts showing in the blood within 3 - 6 months. If the person goes to the HIV test in less than 3 months the virus will not be detected. I hope I could help and you understand.

Answer 3

It is d time period for d virus to become detectable by d tests usually used for diagnosis of HIV.It is usually 3 - 6 months from d time of infection.Its importance lies in d fact that a HIV positive pt might be missed and ironically this is d period during which d patient is highly infective.There are other sophisticated tests to detect HIV during this period but they are not routinely used.

Answer 4

Aperson can test positive for HIV in as little as 25 days but could take up to 3 months. I am always amazed how someone could answer a question with inaccurate information.

Answer 5

The perion between whne a patient detetected and actually affected by the AIDS. It is not neccesarily that a person found HIV positive is a AIDS patient. Sometimes it may take years.
