No, your body will normally clear HPV from your cervix over time. Most of us get HPV soon after becoming sexually active, but our immune system takes care of the infection before it causes any problems.
If you are taking a drug test for a job and it is positive, you will not be able to retake the drug test. However, you can always ask the person giving the drug test of it can be retaken.
The digital pregnancy tests are the same set up as the basic tests. You will urinate on the test (or dip it in your fresh urine) and it will say positive or negative, but if you were to take the test apart the inside has the strip that will show with the one (if negative) or two (if positive) lines. From my experience, sometimes the test will display a negative reading but the strip will be positive with a faint line so always double test a few days later.
no they can only be used once
Yes.
To be exposed to does not always mean that you will be infected. If contracting the disease you will still not test positive until some time afterwards.
because fiirst scientest cal it positive.

Yes. I am not sure what test you are talking about, but tests are not always 100% reliable.

Of course, there's always the chance
If the test showed a clear positive, it is very likely you are indeed pregnant, you should see a qualified medical practitioner for confirmation and advice.
Once someone tests positive for the PPD skin test, that person will (almost)always remain positive for the rest of their life. Then, there is no sense in placing a PPD skin test again, as you already know that it will be positive. The reason for doing the chest x-ray instead is to make sure that there is no evidence of active tuberculosis disease in the lungs. Not all patients with a "positive PPD" will have an active lung disease from TB, which can be contagious.
