There are two different types of pregnancy tests. Both types of test check for the hCG hormone in a woman’s body. HCG is the “pregnancy hormone” and it is the hormone that is produced by the placenta once it begins to grow.
The only time that a woman’s body naturally produces hCG is during pregnancy. One type of pregnancy test checks the blood for the hCG hormone. The other type of pregnancy test checks the urine for the hCG hormone. Read on to learn more about both kinds of tests.
A blood pregnancy test can only be performed at a doctor’s office. Blood pregnancy tests are considered to be more accurate than home pregnancy tests, which are urine pregnancy tests. This is because blood pregnancy tests have little to no room for error, since a doctor performs them. Anytime after the first day of a woman’s missed period is an okay time for a blood test to be done.
Blood tests can quickly pick up any amount of hCG in the bloodstream. Blood pregnancy tests come in two versions. The quantitative blood test will reveal the exact amount of hCG in a woman’s blood. The qualitative blood test will only give a simple “yes” or “no” answer to whether or not a woman is pregnant.
Blood tests can sense hCG sooner than urine tests, so they can actually detect if a woman is pregnant from about 7-12 days from conception, although it is recommended that they aren’t used until a woman has missed a period. Keep in mind that blood pregnancy tests cost more than home pregnancy tests, because they have to be done in a doctor’s office, and therefore you will have to pay for the test and the doctor’s visit both.
Urine pregnancy tests are the regular at home pregnancy tests that we are all familiar with. There are a few different varieties, but most of them work in the same way. Usually you pee in a cup, and then place the test stick into the cup, or you place the test strip into the midstream of the urine. Some tests have you use an eyedropper like device to place urine onto the test strip.
The way the test works just depends on the test you choose. After you take the test, you have to wait the allotted number of minutes before reading the results. Some tests make you wait three minutes, some make you wait 5, and some make you wait ten. It just depends. Once your allotted time is up, your test will give you the results.
Some tests will give you one or two pink lines for a result. Some tests give you a plus or minus sign, and some tests can even tell you “pregnant” or “not pregnant”. Some newer tests will even tell you an estimate of how many weeks along you are. Just make sure when taking a home pregnancy test that you follow the instructions carefully.
