False Positive Pregnancy Test

When trying and tryingyou are trying to have a baby, every result that shows two lines which indicate a pregnancy is a happy moment. Every woman that who ever used a pregnancy home test has read on the box the "99% accuracy" claim. This claim becomes doubtful somehow unsure when other women say that they ended up non-pregnantbeing not pregnant, even though the test showed a positive result. In the next lines, we will go over the most plausible causes of a false positive test.

How does a Pregnancy Test know if I'm Pregnant or Not?

The first step in understanding a false positive is to know how a test works. The pregnant female body starts producing hCG or human chorionic gonadotropin hormone just after conception, sending meSages to the uterus to prepare itself to care for a future child. In the first few days, the hCG levels are moderate in blood but very low in urine. After 10 to 14 days, the levels of hCG go up in the urine too and are now okay ready for to a test.
A pregnancy test has a certain sensibility to hCG, somewhere at the limit of pregnant and non-pregnant (0.25 � 50 mlU), and when the hormone is detected, the markers change color and show you the result. If your level is under 0.25 you're surely non- not pregnant, but when it goes over the limit of sensibility of the test, you are claimed to be pregnant.

Which are the causes Causes of a False Positive Test?

The most encountered cause of false positives is improper technique of testing. Most of the women testing their selvesthemselves are very anxious and forget to read the instruction wriTen on the prospect (tests can have different ways of using them). There are a lot of cases when the faint line of positive disappeared after the processing time was over, so use a clock to count the minutes recommended by the manufacturer. Some of the tests on in the market advice people to double check as every positive test can be doubtable.have wriTen on them the fact that if you double-check it after more than 10 minutes every positive is doubtable.
Another issue caused by human excitement is the faint positive line. When using a home pregnancy test, excitement is generated by the waiting of the results and a woman can overreact when seeing the urine croS over the pregnancy line to highlight the control one, and making it look like it is evaporating. This doesn't mean you are pregnant, but is indicatedit is important to retest after a couple of days in this case.
When receiving a fertility treatment, you have to know that hCG injections are very often used, so pregnancy tests will show positive even though you are not. To have a sure result, wait for a couple of weeks for the hCG levels to normalize.
Medical conditions can also show false positives; some forms of cancer (in the uterus, testicular, ovarian and breast) can influence testing.
Before buying or using urine test, check for expiry date and if it's intact. After using, when checking the results, see if the control line is visible.

When you first see a positive two lines result, think twice about the above lines and if you aren't sure about that result, you have a talk with your doctor and ask him for other directions. You will be advised to retest or to have a blood test to determine the true answer.
