RFSU Early Pregnancy Test has a sensitivity to the pregnancy hormone hCG at 10 mIU/ml. You can test with it 9 days after fertilization/5 days before the expected menstruation.
We recommend testing with morning urine if you want to use an early pregnancy test before your expected menstruation because the hCG level is highest in concentrated urine in the morning.
Pregnancy tests today are of such high quality that they are more than 99% accurate from the day of expected menstruation. The same applies to the Pregnancy Time Early Pregnancy Test Stick.
When using an early pregnancy test and testing before the expected menstruation, the accuracy is lower. Clinical tests on most early tests, for example, show that about 70% of pregnant women will get a positive result on an early pregnancy test 4 days before the expected menstruation. This means that you can still be pregnant even if you test negative with an early pregnancy test before your expected menstruation.
If you test early, you may also risk detecting a biochemical pregnancy, which is a pregnancy that ends within the first few days after fertilization. In this case, you may get a faint positive pregnancy test result that becomes less noticeable over the following days, possibly turning completely negative on the day of expected menstruation.
Yes, it is possible. This is because some women produce hCG (pregnancy hormone) very quickly, while others may take more time.
The time it takes for a fertilized egg to reach the uterine cavity and implant can vary greatly. It can range from one day to one week, and both are considered normal. However, since hCG production typically begins around 9 days after fertilization when the egg implants in the uterus, some women may have a positive pregnancy test as early as one week before their expected menstruation, while others may only have a positive test a couple of days after it.
The reliability of both early and regular pregnancy tests is so high today that it is extremely rare to experience a false positive result. If your test is positive, meaning a colored line appears on the test area within the specified time frame, then you are pregnant.
However, some individuals may still experience menstrual bleeding on or a few days after their expected period, leading them to question the validity of the positive pregnancy test. In most cases, this can be attributed to a biochemical pregnancy, which is the loss of a fertilized egg in the early stages of pregnancy. Nonetheless, if a colored line appears within the designated time frame specified in the test instructions, it indicates an elevated level of hCG, confirming that you are or were pregnant.
Please note that certain medications can cause an increase in hCG levels even when you are not pregnant.
The pregnancy hormone hCG rises rapidly if you become pregnant. That's why pregnancy tests are designed to react to an elevated hCG level, which indicates that you are pregnant.
Pregnancy tests have two antibody lines. One is the control line, which turns color when dipped in urine. If the control line appears with color, it confirms that your test is functioning correctly. The other line is called the test line, and this line only turns color if your urine contains the amount of hCG that corresponds to the sensitivity of your pregnancy test.
The most sensitive early pregnancy tests will show a positive result when your hCG level has reached above 5 mlIU/ml.
