It is a fact that false positive pregnancy test is rare in this age of technology where sophisticated tests have come into practice. However you cannot deny that they do happen. For those trying to conceive, missing a period is an indication that you are pregnant; after which the test may be carried out. False positive results will induce an unnecessary amount of excitement for the people concerned, which eventually leads to disappointment in the end. It is important to know why this happens so that you can avoid these circumstances.
In this article we will be looking at the factors that cause false positive pregnancy test. We will see how different tests, from urine test to blood test, from traditional tests to new digital tests, can lead to false positive results. We will be trying to make it clear whether it is the fault in the test which causes it or whether it is from unavoidable circumstances, after looking at each kind of test one by one. It will also be looking at how you can avoid a situation where you wrongly assume that you have conceived.
Usually it is due to any shortcomings in the test or the way it was carried out, results in a false positive result. It is good to remember that no pregnancy test is 100% accurate; arguably no test in the medical history will is 100% accurate. There is always room for errors in various aspects of the test. When it comes to the pregnancy tests, different tests have different chances of a false positive pregnancy test. The tests may be done wrongly by following the instructions incorrectly; for example making mistakes in the timings of the test. In the next sections we will look into how false positives arise in digital tests and in blood tests.
There is no doubt that digital pregnancy tests are a bit more reassuring. Chances for fake positive digital pregnancy testare very slim. Digital test are said to be far more accurate than traditional tests. In the test of such nature there is very little room for any mistakes in the measurements or in the calculations or in the display of the results. It is also fast to do the test using a digital apparatus, so the tendency to make mistakes is also reduced. Moreover the results don’t need any interpretation in your part; it will simply tell you whether you are pregnant or not. The digital tests work similarly as traditional tests; they test for the hormone human Chorionic Gonadotropin (HCG) in the urine.
The blood test to determine pregnancy works the same way as the urine tests; it too is based on finding the hormone HCG in the blood, the presence which invariably confirms pregnancy in women. The presence of HCG in blood alone is enough to confirm pregnancy, but these tests can also measure the amount of that hormone in the blood for some other purposes. The advantage with the blood test is that it detects pregnancy earlier than the urine test, therefore it decreases the possibility of false negative, forget about false positives. As a matter of fact, what may cause false positive in the urine test also do the same thing for the blood test, so the chance for false positive pregnancy blood experiment is the same?
Sometimes, it can be a case of a faint positive pregnancy test instead of a false positive pregnancy test. It is especially likely when doing the urine test, when doing it at home by you. When doing the test, the color change it is supposed to confirm pregnancy, the formation of any lines or any symbol, can be faint, so it becomes a faint positive. It is worth to remember as these tests look for presence of HCG hormone, not the amount, so the faint positive results can be usually taken as positive results. The faint positive usually is a result of doing the test improperly.
Avoiding wrong positive pregnancy test.
False positive pregnancy test is normally a result of doing the test at home. The most basic test, which is largely urine tests, is done at home by the subject itself, using various commercial products that can be gotten cheaply. Users must rely on the instructions that came with the product to carry out the test. In tests like these, mistakes are very much likely because it is being done by someone who is probably inexperienced. Sticking to the instructions provided along with the product word to word will get a highly accurate result.
When doing the tests at home, users are advised to do the test twice or more to confirm the result and to avoid false positives. Doing the test twice greatly decreases the chances of a false positive. It is also good to avoid false negative, where you are presented with a negative result even though you have conceived; doing the test later on can reveal that you have become pregnant. The general advice is not to rely on a result from a single test.
Alternatively, you can go to any clinic nearby to carry out the pregnancy test. There the tests will generally be accurate as much as possible. However it will be more expensive than doing the test at home and it will take more of your time. When it comes to pregnancy blood tests, they are usually done at clinics, so you will have to go for that. Further, at the clinic they can assess other signs that signal that you are pregnant.
With the tests aside, you can look for other signs of pregnancy to get a hint whether you have conceived or not. The main signs include missing a period that you were supposed to have, vomiting and nausea, development of tender breasts and lower backache. Pregnancy spotting, which involves light bleeding in the vagina, is a good sign of pregnancy, especially if it happens at off periods. If you get a false positive pregnancy testwhile most of these signs are present, then it is advisable to do the test one more time to confirm the results.
