Hiv (Definition)

Hiv infection is caused by a retrovirus....This retrovirus binds to CD4 cells (for the most part). You may detect the virus by several different methods. An elisa test (enzyme linked immunosorbent assay). You may also detect it by doing a test referred to as a western blot (a gel protein electrophoresis). Thirdly by pcr (polymerase chain reaction) which ...Read more

What is 4th gen hiv test window period for hiv-2 I had 7 negative hiv tests from week 4 up to week 19. Can I move on no matter how high risk it was?

What is 4th gen hiv test window period for hiv-2 I had 7 negative hiv tests from week 4 up to week 19. Can I move on no matter how high risk it was?

Window 4 weeks: Yes you can move on. The 4th generation HIV tests include HIV2 as well as HIV1, and the results are conclusive any time 4 weeks or more after the last possible exposure. No matter how high the risk, all tests after 4 weeks were unnecessary. Also, HIV2 is rare outside parts of Africa; I don't know data from Albania, but probably very rare. No more testing needed. Best wishes, stay safe! ...Read more

How blood donations are screened against HIV-2? Can modern screening methods catch HIV-2 if donor is in his acute period (i.e 14 days after exposure)

Hiv screen in blood: Blood donations are screened for HIV 1 and HIV 2 by enzyme immunoassay (EIA) followed by one or more confirmation tests. The windowperiod between infection and the detection of antibody by about 4-7 days. ...Read more

What is the window period for HIV detection?

What is the window period for HIV detection?

3-6 months: Standard HIV screening tests actually test for the presence of antibodies that the body makes to fight the HIV virus. The period of time for the body to make antobodies is called "the window period". It varies in each person, but it is usually between 3 to 6 months. If you have the pcr test looking for viral rna, period is 10-14 days. ...Read more

What are factors that change the HIV window period from 3 to 6 months?

Misunderstanding: Hiv has no window. An exposed individual will experience infection fully within fourteen to twenty one days after exposure. A good HIV viral test will be 100% accurate in diagnosing this infection from that point forward. Antibody testing is slower detecting infection because the human body creates these HIV antibodies slowly. 95% of them, however should be diagnosable at 12 weeks, 100% by 24. ...Read more

What is the window period of HIV test?

Time to turn positiv: After you get infected w/hiv (not every exposure leads to infection), there is a period of time where your tests will remain negative, depending upon you & your test. Therefore, you can also get HIV from someone who tested negative! Assuming they tested during their window period. Check out http://www. Sfaf. Org/hiv-info/testing/hiv-test-window-periods.

What is the HIV window period for occupational exposure?

Variable: The window period is the time from exposure to time a test for HIV becomes positive. The window period depends, in part on the type of test done. Test for HIV nucleic acid is generally positive by three months, usually sooner. Antibody test may take up to a year to turn positive. ...Read more

How are the "incubation period" and "window period" of HIV distinguished from each other?

Difference: Incubation period: time when the person is first exposed to the virus to the time when the diesase start to manifest itself
window period: time it takes for the test used to diagnosed the disease can reliably detect the disease; in HIV the elisa test is used to detect an antibody against the virus, it takes around 2-6 weeks for the immnune system to produce it, during this period elisa is (-). ...Read more

If I'm showing signs and symptoms of hiv, even if its before the window period is up, will I be able to test positive?

If I'm showing signs and symptoms of hiv, even if its before the window period is up, will I be able to test positive?

Depends: It is very unlikely that your symptoms are due to HIV, if you are in the window period. By definition, antibody tests are negative in the window period. If you get a HIV nucleic acid test, that is the earliest test to turn positive in a person with HIV. But a negative result on a test done too soon does not rule out infection.

Window periods hiv test. I had 4 test hiv combo after 94 days negative. But my country state window period 6 month. Malaysia.?

4 weeks. Believe it.: Only a few companies make most of the HIV tests used worldwide. The window period for the combo test (also called duo or 4th generation test) is the same everywhere, 4 weeks. That a particular health department or agency takes a conservative stance and promotes longer periods is a decision based on legalities, politics, and social context. I can't say why some agency in Malaysia says 6 months. ...Read more

If I test negative for HIV three months after my last encounter, should I be fine? 3 months is the appropriate window period right?

That's up to you: Consider yourself healthy if it's one of the new-style tests that's essentially always positive by 3 months (actually quite a bit less). But you will be FINE when you become a mature lover, always loving safely out of respect for your own body and for the other person's. Don't put yourself or anyone else in situation like this again. Think ahead of the love with that one special lifetime person. ...Read more

Is it possible to have a false negative rapid HIV test well after window period (9 months after last possible exposure)? If so, why?

Is it possible to have a false negative rapid HIV test well after window period (9 months after last possible exposure)? If so, why?

Unlikely: When sufficient time has elapsed after one's last potential exposure, HIV tests are usually reliably positive if one is in fact infected. One has to be aware that the usual test looks for hiv-1, but there is also an hiv-2 which is far less common but could be in you and the standard test would not recognize it. ...Read more

Hiv window period debate? Some say that 6 weeks will give you a good test, while others say 6 months. I tested negative at 18 weeks. Is my test con?

HIV window period: Most people develop HIV antibodies within 2-8 weeks of their infection. The average is 25 days. 97% of people will develop detectable antibodies in the first 3 months. Rarely, it can take up to 6 months to develop antibody. If there's concern about acute hiv, a test that measures HIV RNA viral load can be done. The time between HIV infection and RNA detection is estimated 9–11 days. Talk with md. ...Read more

Hiv window period is 3 to 6 months. What does that mean? That HIV will not be detected until after six months? Super confused. Tested neg at 6 months

Hiv window period is 3 to 6 months. What does that mean? That HIV will not be detected until after six months? Super confused. Tested neg at 6 months

The window is open..: Current HIV tests are very sensitive & very specific [a (+) is a true (+) & a (-) is a true
(-)]. Routine HIV tests check your immune systems response to the infection (production of anti-hiv-antibodies). This response (window) can take between 3 & 6 wks. False (+) may be from pregnancy, flu vaccine, auto-immune diseases). If risky behavior (unprotected sex, idu, cocaine) : test early & often! ...Read more

Can pep suppress to detect HIV after window period (3 months) if pep is started after 2 months of exposure assuming HIV virus transmitted?

Post exposure: First pep done two months after exposures would not prevent infection. Nor would it prevent HIV antibody production in the infected person. A regular HIV test would be able to pick that up. Hiv RNA testing would be an invalid screening test while on HIV medication. ...Read more

What effects the window period of hiv?

Two or three windows: From the time of infection, tests for HIV nucleic acid become positive in 1-3 weeks, test for HIV proteins usually becomes positive in an other couple of weeks and antibody test may take up to three months or even longer. The time from infection to the time of detection is called window period. See this site for more info.

Some people have a long HIV window period. Why is that?

Some people have a long HIV window period. Why is that?

Unique immune system: Every person has a unique immune system. Factors such as genetics, nutrition, and other infections (such as other genital infections and other systemic diseases) can impact the 'window' period when the person is asymptomatic. In addition, there are many different strains of hiv, some of which are associated more aggressive behavior than others. Each person's response is unique. ...Read more

Repeated questions: It is offensive and an abuse of this powerful application to keep asking questions that have been answered already. Here is my answer as an?
