All pregnancy tests work by detecting a certain hormone in the urine or blood that is only there when a woman is pregnant. This hormone is called human chorionic gonadotropin or hCG. It is also called the pregnancy hormone.
hCG is made when a fertilized egg implants in the uterus. This usually happens about six days after the egg and sperm merge. The amount of hCG rapidly builds up in your body with each passing day you are pregnant.
Yes. There are two types of pregnancy tests. One tests the blood for the pregnancy hormone, hCG. You need to see a doctor to have a blood test. The other checks the urine for the hCG hormone. You can do a urine test at home with the Zestica Home Pregnancy Test. These days, many women first use a Home Pregnancy Test to find out if they are pregnant before consulting a doctor. The Zestica Home Pregnancy Test is inexpensive, private and easy to use. It is also highly accurate if used correctly and at the right time.
The Zestica Home Pregnancy Test is a `midstream' test. It instructs the user to hold a stick in the urine stream. Then the woman needs to wait a few minutes. Once the time has passed, the user should inspect the "result window."
Most tests have a "control indicator" in the result window. This line or symbol shows whether the test is working properly. If the control indicator does not appear, the test is not working properly.
Most brands tell users to repeat the test in a few days, no matter what the results. One negative result (especially soon after a missed period) does not always mean you're not pregnant. If testing early (i.e. before the date of the expected period) you should always re-test at the time of your missed period.
Laboratory tests show over 99% accuracy. This means that if the pregnancy hormone in the sample is higher than the detection limit of the test, it will show up in the result.
We recommend that you use the Zestica Home Pregnancy Test from the first day of the missed period.
The test can detect lower levels of the hormone, and could therefore detect pregnancy before the missed period. From the day of the missed period the levels of the hCG hormone are usually that high that they give good strong results. Early testing can sometimes give a result that women doubt and they will carry out a repeat test later on.
If a Zestica Home Pregnancy Test is positive and shows that you are pregnant, you should see your doctor. Seeing your doctor early on in your pregnancy will help you and your baby stay healthy.
Yes. It is possible to miscalculate the first day of a missed period. If testing too early, the level of the hCG hormone will still be too low to be detected by the test.
If you test again after a few days you will allow for any miscalculation.
If you keep getting a negative result but think you are pregnant, talk with your doctor right away.
Most medicines should not affect the results of a Zestica Home Pregnancy Test. This includes over-the-counter and prescription medicines, including birth control pills and antibiotics. Only medicines that have the pregnancy hormone hCG in them can give a false positive test result. A false positive is when a test says you are pregnant when you're not. Sometimes medicines containing hCG are used to treat infertility (not being able to get pregnant).
Alcohol and illegal drugs do not affect Zestica Home Pregnancy Test results. But do not use these substances if you are trying to become pregnant or are sexually active and could become pregnant.
