Hiv 1/2 blood analysis:
-antibodies and p24 antigen (chemiluminescence): reactive-2, 741
- IgG antibodies (enzyme immunoassay):nonreactive
in this case, is HIV infection accurate?
Yes: Hiv mutates in response to HIV therapy. If you're being treated without a complete response (partial suppression), the virus can mutate so it can replicate in the presence of the drugs. This usually happens in people who don't take their medications properly. They can then transmit the mutant virus to others. Spontaneous mutation (mutation independent of therapy) has not been a big problem. ...Read more
Bacteria causes Lyme: Borrelia burgdorferi is the bacteria that is the causative agent of lyme disease. It has the most complex genome of any bacteria known to man, which contributes to its ability to infect any organ and to mask itself from the immune system and develop resistance to antibiotics. It is most commonly transmitted by ticks but may be transmitted by other biting/stinging insects, sexually & congenitally. ...Read more
No: no effect on testing.Get a more detailed answer ›
Monotest (target values <1.0=negativ). Values: EBV VCA IgG-Ak 39.9; EBV VCA IgM-Ak 1.1; EBNA-1 IgG-Ak 14.7; EBV DNA (PCR) negativ. What does it mean?
No link: Ureaplasma parvum and most strains of U urealyticum are normal genital tract bacteria, present in the vagina or male urinary tract in at least 50% of healthy persons. UU sometimes causes nongonococcal/nonspecific urethritis in men (NGU, NSU), but no health problems in women are known. There is no link with HIV. Your nearest NHS GUM clinic is an excellent source for additional information. ...Read more
Mosquito bites: West nile virus must be produced in high numbers before being passed through mosquitoes. Birds are far and away the most frequent carriers. Robins look like they might be responsible for spread all over the country. Mosquitoes have to feed on the infected robin and then pass the virus on to human beings through a bite. ...Read moreSee 1 more doctor answer
Evolution: It came from a simian precursor transmitted to humans by one of several mechanisms. This virus mutates continuously and the form to which it mutates which is best capable of surviving under the circumstances is the one which will be reproduced and multiply within infected cells. Unless of course you are a creationist. ...Read more
Yes, but complicated: Trying to tell whether a person has HIV-1, HIV-2, or both, can get complicated. If a person has high risk exposures or has symptoms, he can see an HIV Infectious Disease doctor and trust the advice, but follow-up as instructed. There are many different tests (usually by various manufacturers) in different parts of the world, which happen to have different prevalences for various HIV strains. ...Read moreSee 1 more doctor answer
No: LD is spread by specific species of ticks if and only if they acquire the germ in their life cycle. In the US, Ixodes scapularis, the black legged tick is the main problem for northeast & upper north central US; the western blacklegged tick, Ixodes pacificus is the problem for the west coast. ...Read more
Is hiv-1-pcr quantitative and HIV RNA PCR quantitative same tests?can DNA PCR test be quantitative?
DNA breakdown: Carcinogens can cause cells to rapidly divide in response to the continual attack on their survival. With this high cell turnover coves oxidative/free radical damage (stealing of electrons) and in many case errors in dna sequencing resulted in a mutated dna stand. The body sees this imperfect dna strand as a foreign invader and eliminates it through the immune system. ...Read more
