It’s always a stressful situation when you are taking a pregnancy test, regardless of whether you were looking for a “PREGNANT” or a “NOT PREGNANT” result. A simple yes or no answer might not be enough since you have to deal with quite a bit when taking a pregnancy test, and for your peace of mind, the test result needs to be 100% correct. However, is every pregnancy test 100% right? The short answer is no and the following factors have to be considered.
If the pregnancy test results are not 100% reliable, it could be because you took the test too soon. Other factors that might affect the results of the test include being on fertility drugs, the test is past its expiration date, or certain medications.
Did you get a double line, but were hoping for a single line? Did you get a single line, but wanted a double line? Either way, you want to know that the test is 100% correct. What could produce false readings even on the best available pregnancy tests?
1. Testing Too Early
It is possible to get a false negative result. Taking the test just after conception is one of the most common causes for a false reading, particularly if the woman’s menstrual cycle is usually irregular or if she isn’t sure of the date of her last period. When is the best time for women to take a pregnancy test? Allow a minimum of two weeks following intercourse before taking a home pregnancy test.
2. HCG Interference
Even though false positive results are rare, they do happen. Some potential reasons are a mistake by the operator, specific diets, hCG interference resulting from infertility treatment, hCG secreting tumours and when the pituitary gland secretes hCG, mostly in women that are perimenopausal.
These situations are rare, so don’t worry and if the test is positive, enjoy it until your doctor tells you otherwise.
3. Choice Of Test
The accuracy of pregnancy tests can vary. It doesn’t mean the test that cost the most are the most accurate. Similarly, the cheap test could produce good or bad results. Always purchase a pregnancy test from online websites or stores that are reputable and be sure that the packaging has FDA and CE approval so that you know you can trust the test you are buying. At Zoom Baby we only stock highly-reliable pregnancy tests with a minimum accuracy of 99% when used correctly.
4. Expired Tests
Similar to medications, once a home pregnancy test has expired, it loses its accuracy and “potency”. Pregnancy tests have a shelf life of 2 to 3 years after production date. The cheaper ones usually have a shorter lifespan.
5. Medication Interactions
Although food won’t directly affect a pregnancy test results, some medications can. Certain medications used for infertility treatment, as mentioned earlier, along with specific diets, could produce a false-positive result.
Although urine and blood tests carried out by the doctor produce the most accurate results, in the majority of cases, if you have a missed period and a couple of dark lines on your home pregnancy test, there is a high probability that you are pregnant and the test is correct.
