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 kind of HIV test has a good accuracy for one month since last encounter?

Blood or swab: You can have a blood test or the swab test, they are both accurate. Typically most physicians will tell you if you're unsure of your exposure to get tested as far as 6 months post exposure to confirm you haven't been exposed to the virus. ...Read more

Hi, Had unprotected sex first encounter didn't even last 5 minutes, chances of hiv?

Hi, Had unprotected sex first encounter didn't even last 5 minutes, chances of hiv?

Low: Though your chance of infection with HIV after one unprotected sexual encounter is low, it is not impossible. It would be wise to be checked and to avoid unprotected sex in the future. Risk of infection increases if your partner is diagnosed with HIV, if you engaged in anal sex and if any bleeding occurred during sex. Any unprotected sex increases risk regardless of how long the encounter lasts. ...Read more

Not HIV: Congratulations on your adventure. Anytime another person allows even some simple loving, you should be pleased and feel that life's good. I'm sorry this led to your being frightened. Paper cuts are sealed securely with fibrin and you won't get infected through them. And the onset time for HIV isn't so fast. ...Read more

What is the chance of contracting the HIV virus from a dentist's visit?

What is the chance of contracting the HIV virus from a dentist's visit?

Close to zero!: A dentist's office is probably one of the safest places you can go to. The only thing that comes to mind that might be even safer is a hospital operating room or surgicenter. If you like worrying, what about a restaurant or escalator or door handles to stores, etc. Anyway, the answer is practically zero. Trust your dentist and the sterility of his office and procedures or find another dentist. ...Read more

Possible to have contracted HIV from risky encounter 4 years ago given. 13 neg AB and RNA tests. Current CD4 count 1, 600 CD4/8 ratio 2.6. wbc 16, 000?

Nope, not possible: The HIV blood tests are among the most accurate diagnostic tests ever developed, for any medical condition. It is impossible to have HIV with antibody and RNA testing both negative more than a few weeks after the last possible exposure. ...Read more

Is two months after the last encounter a good amount of time if person tested negative for HIV?

Is two months after the last encounter a good amount of time if person tested negative for HIV?

Depends on test: If the test was HIV nucleic acid test, that is good, though even that should be repeated in about 2 months. Antibody tests being negative is not nearly as good and should be redone every couple of months for a year. Please note that post-exposure treatment is generally effective and, God forbid you are in a similar predicament again, seek care as soon as possible, after exposure. ...Read more

Do I have to take more tests for hiv if I tested and the person I had encounters with tested negative as well? Can I take the results as conclusive

Do I have to take more tests for hiv if I tested and the person I had encounters with tested negative as well? Can I take the results as conclusive

Probably yes: If your partner is negative for HIV, it is exceedingly unlikely s/he is infected. But even if exposed to a known infected person, a negative HIV antigen-antibody blood test (i.e. 4th generation test) is usually conclusive by 4 weeks and always conclusive 6 weeks or more after the last exposure. ...Read more

If I test negative for HIV after 6 weeks and 12 weeks after last encounter, should I stop worrying?

Love wisely: I see that you're 18, and I'm very pleased you're asking. It shows you plan to love carefully and wisely until you're in a permanent, monogamous relationship. Consider yourself HIV-negative, be thankful for good health, and use barrier protection from now on until you're ready to be a father. Best wishes. ...Read more

I had a low risk encounter I was tested non reative both at 6 months mark and 2.5 year mark by rapid hiv test is the test conclusive?

Yes: If the test was negative at 2.5 years after potential exposure, you can stop worrying about HIV. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.

Over ten years ago I had unprotected encounter. I have taken two oraquick test last couple of weeks. Both were negative for hiv. Am I safe?

Yes: From the oraquick website - Oral fluid HIV tests are very accurate. In studies, the OraQuick oral fluid test detected 91.7 percent of people who were infected with HIV, and 99.9 percent of people who were not infected with HIV. If you have more questions about oral fluid HIV tests, talk to your doctor.
It is ten years that is good. I agree that it is best to discuss with your physician. ...Read more

I want to take a HIV test. It's going to be a month since my first and last encounter. What test would you doctors recommend would be most accurate?

PCR: If you have reason to think you may have been infected, and you want to be certain, the polymerase chain reaction though pricey will give you your answer with a month gone by, you're a man now; I'm glad you experienced love even if it was less than perfect, and that you'll always love wisely and safely. Your life has new joys and new responsibilities. Best wishes. ...Read more

What are the initial symptoms of HIV and what is the minimum window in which it can be detected after unprotected encounter with opposite or same sex?

What are the initial symptoms of HIV and what is the minimum window in which it can be detected after unprotected encounter with opposite or same sex?

Flu-like: The initial symptoms of HIV may be very nonspecific, such as flu-like symptoms; muscle aches, fatigue, low-grade fever, lymphadenopathy. The minimum window for detecting HIV is about one month, however, seronegative patients who are suspicious of exposure to HIV should be retested after 3-6 months due to possible later seroconversion. Be safe. Practice safe sex, use condoms! ...Read more

Had encounter where I topped a rumored hiv person, used a condom I'm terrified, how early can I test? Dunno why I keep putting myself in these situatio

Duo test at 4 weeks: This was a safe exposure, assuming the condom remained intact, and the chance you were infected was zero for practical purposes. If you feel you need testing anyway, have a duo ("4th generation") test at 4 weeks, when a negative result will be conclusive. In the future, always ask partners about HIV status, and no sex (even w/ condom) with positives not on treatment. Then no worries! ...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
