There are a number of different early pregnancy test types that can be used to check if a woman is pregnant or not. The most common early pregnancy test used by women nowadays is the home pregnancy testing kit. These kits can be bought from pharmacies and drug stores and are an extremely reliable form of the early pregnancy test. A home pregnancy kit usually claims to be at least 97% accurate.
It is highly unlikely that a positive result from an early pregnancy test is going to be false. However, these home pregnancy kits are not as accurate if you use them less than 7 days after a missed period. This is because the levels of hCG in the urine are only going to be small for the first few days of pregnancy and this can lead to them not being detected by some of the early pregnancy test kits.
There are a variety of brands of early pregnancy test kit available and these are constantly striving to be able to detect smaller amounts of hCG in a woman’s urine. It is still bested to use a pregnancy test kit around a week after your period is missed. If you have a negative result then you can always re-test with another early pregnancy test a week later to double-check the result. This will allow the hCG levels to have risen to a level where they are guaranteed to be detected by the early pregnancy test kit. The best time to use an early pregnancy test kit is first thing in the morning when the urine has built up over night.
Doctors and other health professionals can use a blood test to perform an early pregnancy test. This can be done much earlier than a home pregnancy test kit can. In fact, this pregnancy test can be performed 7 days after you ovulate which is about a week before your period is due and still provide accurate results. The accuracy of a blood test being used for an early pregnancy test can be at least 99%.
Again, it is important to perform another early pregnancy test if the first was negative and you still have not had a period a week later. Your doctor will also take into account any other factors that may lead to you missing a period before he orders another pregnancy test. Sometimes, there can be mistakes made by the testing lab which affects the result of the early pregnancy test and it is worth having a retest if there is any doubt over the accuracy of the test result.
