Early Diagnosis With HIV Test Kit Saves Lives
Today, exposure to HIV is not the death sentence it once was. These days, access to a diagnosis has grown with test sites making HIV testing available to people anonymously. In fact, now there is an even better solution for initial testing – HIV test that can be done in the privacy of your own home.
For some, going to a clinic for testing can be a source of embarrassment or fear. Regardless of what the test result is, the disgrace of having gone to a place that tests for HIV might be difficult to shrug off. Having access to an affordable product that gives results within minutes, is safe to use and can be used in the privacy of home may result in early diagnosis of HIV cases. This can help treat HIV in its early stages.
Used correctly, a home testing product can be the answer to more expensive, time-consuming laboratory tests. This is however not a substitute for laboratory testing which should be sought after an initial positive result. In other words, the HIV Test Kit (www.hiv-test-kit.comhttp://www.hiv-test-kit.com) is not meant to replace any medical testing or treatment, instead it is meant to be an important step in the process of early diagnosis.
The HIV Test Kit is an affordable product that gives rapid results for HIV-1 and HIV-2 screening tests at home. It is the goal of the HIV Test Kit’s manufacturers to provide a means to reduce the number of cases of HIV infections that go undiagnosed in the early stage. Early diagnosis and treatment are the keys to successfully managing HIV infections and preventing the spread of the disease.
Knowing that access is crucial in making home-testing a viable step in the process of early HIV diagnosis, the manufacturers of HIV Test Kit have made their product available worldwide over the internet. They also sell at the street level at discounted prices to people who are most at risk. Knowing that this is a global issue, they have marketing efforts based in areas where sex tourism in popular. The HIV Test Kit complies with World Health Organization standards but may not be available in all countries as some prohibit home-testing.
If you think you’ve been exposed to HIV, don’t put off getting tested. With a 99.9% accuracy rate when properly used, the HIV Test Kit (www.hiv-test-kit.comhttp://www.hiv-test-kit.com) will allow you to get quick, reliable results in the privacy of your own home.

1. The negative predictive value is not just a function of its sensitivity, it is also a function of the the actual rate of HIV infection in the population you are testing. The sensitivity of the SUDS test is 99.4%, but the negative predicitive value depends on whether you're testing a high prevalence or low prevalence population.
Let me illustrate:
Leaving specificty aside for a moment,
If you test 1 million people, 1% of whom actually have HIV, you would expect 990,000 negative tests. However a test with 99.4% sensititivity will miss 60 out of 10,000 that should have been positive. That means 60 out of 990,060 negative tests were wrong – there is a 0.00606% chance (roughly 1 in 16,000) a negative is a false negative.
If 100% of your million population have HIV you would expect 0 negative tests. However the test misses 0.6% of true positives, so in fact you would get 6,000 (false) negatives – and there is a 100% (1 in 1) chance that any negative is a false negative. This is why you need to know the background prevalence of a condition before you can interpret the chances that any given negative test is a true or false negative.
If the true prevalence of what your testing for is 0.3% (as is HIV in the US population) a test with 99.4% sensitivity will result in 1 in 55,000 negatives being false negatives.
Of course no test is totally specific either – there will be fewer negatives because some will be false positives.

2. Yes. All screening tests for HIV sacrifice specificity to maximise sensitivity. This is why a diagnosis should not be made on a positive screening test alone. You need a two step algorhythm for adequate specificty in most populations.
3. Not quite: it is the ELISA plus WB (the two step algorhythm) which provides the specificity, not just the WB alone.
4. No it's not the same, but they are believed to have comparable accuracy.
