Home pregnancy tests - BabyCentre UKHome pregnancy tests can tell you if you are pregnant by detecting the presence of a hormone called human chorionic gonadotropin (hCG) in your urine.
This hormone is produced by the cells that will develop into the placenta. It first enters your bloodstream when the fertilized egg starts to implant in your uterine lining, as early as six days after conception.
The amount of hCG in your body then increases rapidly over the next few weeks, often doubling every two days or more. When the test detects a hormone in your urine, it will show a positive result.
Some home pregnancy tests claim they were sensitive enough to provide positive results as early as five days before you expect the next period. And some women will have produced enough hCG to get a positive result at the time. So if you want to know and do not mind spending money, go ahead and try it. If you get a negative result, you can just wait and test again later if you still do not get your period.
Most of the home pregnancy tests claim to be "greater than 99 percent accurate" if you use it on the day you miss your period, but one study found that some tests are not sensitive enough to ensure the results are accurate at the time well.
researchers evaluated the pregnancy tests from different manufacturers and found that only one brand of test (both versions of digital and non-digital) is 97 percent accurate in detecting pregnancy on the first day of a missed menstrual period. (The amount of hCG in urine at this time can vary a lot from one woman to another.) More brands pregnancy correctly predicted about half the time
The bottom line :. You will be easier to obtain accurate results if you wait a few days to a week after you expect the period prior to testing.
According to the regulations the Food and Drug Administration (FDA), the home pregnancy test can claim to be "greater than 99 percent accurate" if producers showed only done test well in the lab as a test that is more than 99 percent of the time. home pregnancy tests today more sensitive than previous products, so it is not surprising that manufacturers are able to make this claim, but it has nothing to do with the ability of a test to detect pregnancy at the time of the missed period.
It's not easy. new products come out often, and manufacturers can make improvements all the time
But some package inserts provide information about the sensitivity of this test -. ie, they reported the lowest concentration of hCG in milli-International Units per milliliter (mIU / ml) of urine that the test can detect. For example, a pregnancy test that claims to be able to detect hCG at 20 mIU / ml should theoretically be more sensitive than one that claims to detect it at 50 mIU / ml.
First check the expiration date on the package, especially if you've had for a while. If you have saved anywhere tests that gets moist or warm, such as bathrooms, may have deteriorated. If that happens, it is better to throw it away and get a new one.
For the best results, try to test first thing in the morning, when your urine is most concentrated. Read the directions carefully because they vary with different brands. Some require you to urinate in a cup and then use the pipette provided to put a small sample in the test wells. With others, you can urinate directly into the testing device. And some will let you do both.
The tests also vary in how they present the results. For example, some show pink or blue lines on the test strip, while others reveal a red plus or minus sign in the window. "Digital" test tells you in words if you're pregnant. Most have a control indicator (often a second line or symbol) to indicate whether the test is valid.
It can take up to 10 minutes to see the results. If the control indicator does not appear correctly, the test may be damaged. If this happens, you can usually contact the manufacturers and they send you a new one (although it may not come immediately to use the same month).
If you have questions about how to use the test, contact the manufacturer's toll-free number on the package instructions.
If the test shows a negative or result, wait a few days or a week and try again if you still do not get your point. One possibility is that you are ovulating later in your cycle than you think and take the test too early to get a positive result.
So do not assume that one negative result means that you are not pregnant. The amount of hCG produced is different for every woman and varies with each pregnancy. Just because you are positive at the beginning of your first pregnancy does not mean you will be a positive beginning in the second one you.
If you still do not get your period (or positive result) a week or so after you expect it, contact your health care provider
False positives are rare, but they can occur under certain circumstances ,
If you have an early positive results and then get your period soon after that, you may have what is sometimes called a chemical pregnancy. This means that a fertilized egg implanted in your uterus and developed just enough to start producing hCG but then stopped growing for several reasons. Forms of early miscarriage usually occurs when a fertilized egg has a disability that prevents it from growing normally.
After a chemical pregnancy, your period may be a little heavier and a few days later than usual. When the pregnancy test is less sensitive than it is now, these very early losses were never identified. Some health care providers think that another good reason to wait until a week after your period is due to take a home pregnancy test
Note :. A pregnancy test usually results in a positive, but sometimes negative because lower levels of hCG. No matter what kind of results you get from a pregnancy test, call your health care provider right away if you:
Most health care providers use a urine pregnancy test, just like you do at home. However, your provider can test your blood and to determine appropriate levels of hCG or see what is happening with the rate from time to time - to find out if you have a miscarriage, for example. It takes anywhere from one hour to one day to get the results of blood tests.
You can buy them at most drugstores and online. They generally cost between $ 6 and $ 20, and usually contain two or three tests. digital test usually costs more, and a bulk package testing strips cost less.
There is a testing company that will allow you to pay online and then go to the lab and had blood samples taken. Testing companies will provide you with your results the next day by phone or online. These tests range from about $ 40. They claim to be able to provide accurate results as early as 6 to 8 days after ovulation.
