No , but a negative test can be a false positive .
yes
A pregnancy test can NOT be reused and it will not show a accurate answer.
If semen fertilizes a woman's egg, the result of the test would turn from negative to positive. Otherwise, the presence of semen would have no effect on a pregnancy test.
It may do and it may not do it depends how far into the pregnancy you are - I had an eptopic pregnancy earlier in the year - I took a test when my partner was away and it was positive he was returning in a few days so I waited coz I wanted him to see a positive test for himself - the second one I did was negative, so was the 3rd 4th and 5th I did so many as I knew for definite I was pregnant - after going to the doctors and getting a blood test and one the following day I was taken in for scans due to the hormone level dropping. The hormone level will rise with an eptopic pregnancy and then drop so dependant on when you do the test depends on whether it will turn out positive or not. Please go to the doctors and have a blood test and scans if you suspect you have an eptopic pregnancy. It is a horrible horrible thing to go through and the earlier you find out and get the proper care and support the easier it is to get through and start trying again! I hope this helps!
you can take a pregnancy test whenever you please. if you take it anytime after your missed period though, your test will turn out more effective.

If you dip a test in Pop sometimes it will turn positive
Hello there. Yes you may very well be pregnant. A pregnancy test will only turn positive once HCG has been found in your urine. BUT there needs to be ENOUGH HCG in your urine to make a positive test result. Depending on the pregnancy test, they usually look for 5MIU - 50MIU. If you had 49MIU of HCG in your urine and did a test that looks for 50MIU it would be negative. The same thing applies to the Labatory urine pregnancy test. When they did the test you probably didn't have enough HCG in your urine to give you a positive. You need to have a blood test. Urine tests are NOT reliable and give negative results when women are indeed pregnant. See your doctor for a Quantitative Beta HCG pregnancy test. Good luck.
an ovulation predictor kit will turn positive when a woman is pregnant. Positive means the test line is darker than or the same as the reference line, so a light test line does NOT mean a positive pregnancy test like it does if using an actual home pregnancy test!
yes, but it depends on the brand that you purchase
You can take a pregnancy test at any time, even if you are on the birth control pill. The test will turn positive no sooner than 10 days after conception.
There are a few factors that can result in a false positive. Most of the time though false positives are rare! I recently experienced this. I have 4 children and have never had a false positive! My test never showed up unless I was pregnant. I recently had 5 tests show a faint positive and went to the doctor for blood test which was negative. I was told that a cyst on your ovaries can sometimes make a test appear positive (false positive). Other factors include chemical pregnancy. This is one where everything develops as though you are pregnant, except for the baby. If you are on any medication that contains the pregnancy hormone (HCG), this also can make your test turn up positive. It is best to have a blood test done by the doctor to totally insure you are not pregnant.
the solution will turn a 'brick red' colour if positive but will stay blue if negative.
Negative, something like Micrococcus Luteus would be positive. If positive the it means the urea can produce pneumonia with the bacteria and the broth would turn a hot pink color. We had to test seven different organisms and the Urea broth was one of the test.
