All hpt's say don't read the results after a certain amount of time. If you got a pos. you are pregnant wether or not the results dissappered later.
AnswerHonestly I have to disagree with the first response. I work in an Ob/Gyn office and I have always been told that a true positive should last 48 hours, while a negative should not be read after ten minutes. My positive HPT did in fact last well beyond 24 hours. It all depends on the brand of the test. I have had a rocky past with HPT's. If you want to be sure, go to your doctor and ask that they either give you a blood test in the office or refer you to a lab for a quantitative HCG serum test. The quantitative serum test will not only tell you yes or no, it will give you your actual levels of HCG in the body. This can help the doctor determine your dates if you do not know the date of your LMP. It can also tell him/her how the pregnancy is progressing. Good luck! AnswerIt should not take take long the result to come out any result that comes out after 10 min most likely is the wrong result.Wiki User

How long after implantation bleeding will a positive test result?
I believe it may take 2-5 days in order to allow the pregnancy hormones to build up to a level where they can be detected by a home pregnancy test. Having said that, I took a pregnancy test within hours of having an implantation bleed with my son and it appeared positive within seconds!
Do drug test results take longer if they are positive?
No. A drug test is a colored strip dipped in the urine. The person administrating the test has to let the strip sit in the cup or urine for about 15-30 seconds to ensure an accurate result. If the strip had a certain code, or color on it, then it will show either positive or negative. Either way it takes relatively the same length of time.

One way to answer this question is that climate is a part of the system than can feed nature, probide positive shelter for all living organisms as positive. As negative, this same system can tare houses into shreds in seconds, it kills nature and has no direct control, making it unique. Negative aspects are as ugly as positive effects are beautiful.
