Are Some Pregnancy Tests Better Than Others?
Whether planned or unplanned, with any suspicion of pregnancy the first thought is usually about getting a pregnancy test. For planned pregnancies, one of the most anxious moments is knowing that you are absolutely, positively pregnant. Seeing that ‘red plus’ sign can be nerve racking and exciting – but testing too early without the best pregnancy test will more than likely provide you with an inaccurate result. However, many women are so anxious they tend to take a pregnancy test before there is any detectable trace of pregnancy hormone in their system which would give the correct result.
Understanding how pregnancy tests work and knowing what pregnancy test is best can put a stop to the anxiety and worries. Firstly, there are two main types of pregnancy tests, the urine test and the blood test. The blood test is done in a doctor’s office while the urine test is usually the one the woman can do herself at home. HCG is detected once implantation occurs, that is the fertilized egg has been attached to the uterus.
Conventional wisdom is that it is best to wait at least one to two weeks after you have missed your period to perform the test. This makes it less likely that you will get a negative result if you are indeed pregnant.
How Pregnancy Tests Work
Pregnancy tests work by checking the level of HCG (human chorionic gonadotropin), the pregnancy hormone present in urine. Once upon a time, pregnancy tests could only give a positive result after a woman had missed her period. This was the case because these early tests could only read HCG of over 120 mIU and were not very sensitive. All of that has changed in recent times with the creation of some very sensitive and highly efficient pregnancy tests.
Early Pregnancy Test
For those anxious for a response, there is definitely a difference in early pregnancy tests. Some manufacturers claim that their test can measure HCG after just 6-12 days post ovulation. Only one test has been proven to pick up HCG levels when they are as low as 20 mIU. Even with this, only about 80-85 percent of women who are pregnant will get a positive result about one week past ovulation.
While most tests will give a correct result one week after a missed period, we have chosen through our own research what pregnancy test is best. First Response, according to a number of surveys is 95 percent accurate before other pregnancy tests. In fact, First Response can be generally be used even before the first day of a missed period. Some reviews posted online state that First Response can detect the presence of HCG a few days after implantation occurs, that is up to three days before the due date of your next period.
Some other highly rated pregnancy tests include Clear Blue Digital Test, e.p.t Pregnancy Test and Equate Pregnancy Test. These and other early pregnancy tests have registered positive results after an average of 10 days past ovulation or a few days after a missed period. However, for best results, pregnancy tests should be done with first morning urine which would have the full concentration of HCG in it.
There is one negative to testing early, and that is undergoing an early miscarriage and knowing it. In many cases, most women who suffer an early miscarriage that is before or around the time of their menses would not know that they have miscarried.
Of course it is worth remembering that the more efficient the pregnancy test, the more expensive it is. This is however a negligible cost compared to other related expenses. It does however act as a caution against testing too early. In a negative result is produced and the pregnancy symptoms persist, then the woman would have to test herself again. In this context, it may be better to start with one of the more efficient tests such as First Response.
