A pregnancy test is used to determine whether or not a woman is pregnant. It can be done in a number of ways, but the most common method is by measuring the level of human chorionic gonadotropin (hCG) in a woman’s urine or blood. At-home pregnancy tests are readily available STD Home Tests and relatively simple to use, but it’s important to understand how they work—and how accurate they are—before you take one.
Most at-home pregnancy tests claim to be 99% accurate when used as directed. However, this number only applies if the test is taken on or after the first day of your missed period. If you take the test before your missed period, you may get a false-negative result—meaning the test will say you’re not pregnant when you actually are.
There are a number of reasons why this can happen. First, hCG levels rise at different rates in different women. Second, some tests are more sensitive than others and can detect lower levels of hCG. Finally, taking the test wrong can also lead to false negatives. For example, if you don’t wait long enough for the results to develop, you may see a negative result when you’re actually pregnant.
On the other hand, it’s also possible to get a false-positive result on an at-home pregnancy test—meaning the test says you’re pregnant when you actually aren’t. This is much less common than a false-negative but can still happen for a number of reasons. For example, if you take certain medications (like antihistamines), have been recently pregnant, or have an ovarian cyst, you may get a positive result even though you aren’t pregnant.
Types of Tests
There are two main types of at-home pregnancy tests: urine tests and blood tests. Urine tests are by far the most common and can be done with or without a kit. To do a urine test without a kit, simply collect your urine in a clean cup and dip a strip of family planning paper into it. The paper will change color to indicate whether or not you’re pregnant—but it’s important to note that these strips are not as accurate as pregnancy tests that come in kits from the store.
To do a urine test with a kit, follow the instructions that come with the kit very carefully. Usually, this involves urinating onto a stick and waiting for a certain amount of time to see if two lines appear in the results window. If two lines appear (one line may be faint), you’re considered pregnant; if only one line appears or if no line appears at all, then you’re not pregnant. It’s important to note that some kits require that you hold the stick under your urine stream while others require that you collect your urine in a cup first and then dip the stick into it. Be sure to read the instructions carefully so that you don’t make any mistakes!
Blood tests are less common than urine tests but are considered more accurate since they measure hCG levels directly from your blood instead of relying on your urine concentration levels. That being said, blood tests also tend to be more expensive and require more effort since you have to go to a lab to have your blood drawn (although some hospitals offer at-home blood testing kits). If money is no object and accuracy is your top priority, then go ahead and opt for a blood test—but remember that urine testing is still pretty darn accurate!
