A pregnancy test measures the level of the hormone human chorionic gonadotropin (hCG) in the blood or urine. Most home pregnancy tests are designed to detect levels of hCG as low as 20 mIU/ml.
Most pregnant women will have a hCG level of at least 25 mIU/ml by the time they take a home pregnancy test 3 weeks after their last period. So, if you take a home pregnancy test 3 weeks after your last period and your hCG level is 25 mIU/ml or higher, the test will be positive.
Two Line On Pregnancy Test
Pregnancy test results are either positive or negative. A positive result means that you are pregnant, while a negative result means that you are not pregnant.
How Accurate Are At Home Pregnancy Test
It is estimated that around 10 million home pregnancy tests (HPTs) are sold each year in the United States.1 HPTs are used to detect the presence of the hormone human chorionic gonadotropin (hCG) in urine. hCG is produced by the placenta and is the earliest detectable marker of pregnancy.
The first home pregnancy tests were introduced in the early 1980s. HPTs have come a long way since then, and most are now very accurate. In general, the accuracy of HPTs decreases as the length of the pregnancy increases. The accuracy of HPTs also depends on the stage of the pregnancy. Most HPTs are accurate when used at the time of the first missed menstrual period (the day after the expected period).
HPTs that use a blood sample, such as Clearblue Easy and First Response, are more accurate than those that use urine. However, blood tests are more expensive and are not available over the counter.
Most HPTs are accurate when used at the time of the first missed menstrual period (the day after the expected period).
A study published in the New England Journal of Medicine in 2002 looked at the accuracy of home pregnancy tests. The study included 988 women who used an HPT and 594 women who had a blood test to determine whether they were pregnant. The study found that the HPTs were accurate 98% of the time when used at the time of the first missed menstrual period.
A study published in the journal Obstetrics & Gynecology in 2006 looked at the accuracy of HPTs in the second trimester of pregnancy. The study included 1,146 women who used an HPT and 992 women who had a blood test to determine whether they were pregnant. The study found that the HPTs were accurate 91% of the time when used in the second trimester.
Overall, HPTs are very accurate when used at the time of the first missed menstrual period. However, they may not be accurate in the later stages of pregnancy. If you are concerned about the accuracy of your home pregnancy test, you should consult your doctor.
Plan B Pill Inside Pregnancy Test
What if you could take a pregnancy test that also told you whether or not you were carrying a pregnancy that would require taking the Plan B pill?
Now there is a pregnancy test that can do just that. The Plan B One Step Pregnancy Test is the first and only over-the-counter pregnancy test that can tell you if you need to take the emergency contraception pill, Plan B.
The Plan B One Step Pregnancy Test is a qualitative test, which means it can tell you if a substance (in this case, the hormone human chorionic gonadotropin, or hCG) is present or not. If the test detects hCG, it means you are pregnant. If the test does not detect hCG, it means you are not pregnant.
The Plan B One Step Pregnancy Test is 99% accurate in detecting pregnancies that will require taking the Plan B pill. That means that if the test results are positive, there is a 99% chance that you will need to take the Plan B pill. If the test results are negative, there is a 99% chance that you will not need to take the Plan B pill.
The Plan B One Step Pregnancy Test is easy to use. Just follow these simple steps:
1. Collect a urine sample in a clean, dry container.
2. Remove the cap from the test.
3. Hold the test stick in the urine stream for 5 seconds.
4. Place the test stick on a flat surface and wait for the results.
The test results will be displayed in just 5 minutes.
The Plan B One Step Pregnancy Test is available at drugstores and other retail outlets. It costs about $20.
Pregnancy Test Line Getting Lighter
If you are pregnant, your pregnancy test line will get progressively lighter as the days go by. This is due to the hCG hormone which is released by the placenta. The hCG hormone starts to show up in your urine about 10 days after conception and doubles every two to three days. So, the lighter the test line, the more hCG is present in your urine.
It is important to remember that not all pregnant women will have a positive pregnancy test. If you are trying to conceive, it is a good idea to wait until at least 10 days after your missed period to take a home pregnancy test. This will give you the most accurate results.
