yes
This happened to me when I got pregnant with my third child. The first test was negative and the second positive. From what I understand, a pregnancy test can give a false negative but rarely gives a false positive.
Lab technician tests are often two part exams. The first part usually contains a written portion and the second part is a hands-on skills test that mimics similar skills to usual work.
Try one more time. If it is again positive, then you probably are pregnant.
Yes. Sometimes pregnancy tests are not 100% correct. Even if the second test comes out negative I would recommend that you go see your doctor. They can just give you a pregnancy test there and then you will know for sure. :)
An MRI technician test is the final test you must take to be able to conduct MRIs after all your training is complete. If you pass the test you are certified to become an MRI technician.
A person may be infected with HIV, but not test positive. It will take time for the virus to spread throughout the body and therefore when they first get infected they will often yield a negative test result since the concentration in the body at that time is still very small. After 3 months if a person tested negative the first time and negative the second time there is very little doubt on whether or not the patient has HIV. However, without the second test 3 months later a person who recently got infected before the original test would have shown a negative test result and actually had HIV.

The chances of a false negative chlamydia test result with the newest test kits may be as high as 10%. The chances of two false negative results are 1%, and of three are one in one thousand. Having a negative result followed by a positive normally means that you were infected with chlamydia between the first and second test.
