Frequently Ask Questions (FAQ) about YES or NO

The “Yes or No” early pregnancy test detects a hormone in the urine that the female body produces during pregnancy (human chorionic gonadotropin, hCG). On average, the concentration of hCG doubles every 2-3 days and increases continuously within the first 12 weeks of pregnancy.

The Yes or No early pregnancy test has always been characterized by its high degree of sensitivity. We have now even been able to improve the lowest sensitivity limit (sensitivity) of our early test from the original 25mIU / ml to 10mIU / ml. With a sensitivity of only 10mlU / ml hCG, the “Yes or No” is the early pregnancy test with the highest possible sensitivity. Even with a sensitivity of 25mIU, we were able to detect the hCG hormone, which indicates pregnancy, on the 10th day after conception. Since the hCG hormone doubles every 2-3 days, one can expect that we will be able to provide evidence about 2 days earlier, i.e. about 8 days after conception.

It should be noted that the length of the cycle varies from woman to woman and can be between 21 and even in isolated cases up to 42 days. On average, it is around 28-32 days. Ovulation normally takes place in the middle of the cycle, i.e. around day 15 after the last menstrual period if the cycle is longer. The egg cell can only be fertilized for about 12-24 hours and a fertilized egg cell then nests in the uterus after about 3-5 days. Assuming a cycle length of 32 days, the 10th day after possible conception is about 6 days before the expected period. With the increased sensitivity to 10mIU or in the case of an even longer cycle, the hCG hormone and thus pregnancy can be detected even earlier before the expected period.

Regardless of the fact that you may want to test very early, the most sensitive test on the market also gives more security and accuracy, as the length of the cylinder varies with many women. It can therefore happen that a woman does a pregnancy test several days earlier than expected. Other pregnancy tests that often only have a lowest sensitivity limit of z. B. only have 50 mIU, would thus possibly show a false-negative result.

All cycles that are 23-35 days in length are now considered normal. The cycles, which tend to be longer, occur more frequently than the shorter ones. Every 6th cycle lasts 33 days or more. And every 10th cycle lasts 24 days or less. If one looks at the cycle lengths of the individual women, it turns out that no woman has a rigid individual cycle length. In 60% of all women, the cycle length fluctuates by more than a week within a year. Of these 60%, almost every second person experiences fluctuations of more than two weeks in the course of a year. In almost 30% of all healthy women, the cycle length fluctuates, for example, between 24 and 38 days or between 28 and 42 days. Fluctuations in cycle length are therefore part of the cycle of healthy women and do not per se mean that there is a menstrual cycle disorder. These healthy fluctuations also provide an explanation for why a rigid division into fertile and infertile days does not make sense. A meaningful and appropriate division into fertile and sterile days can only be made for the individual situation of a woman.

Since the test is highly sensitive, it can also be tested at any time of the day, but the morning urine usually has the highest hCG concentration.

In laboratory tests as well as in clinical user studies, the “Yes or No” early pregnancy test provided over 99% correct results.

Drugs containing hCG (e.g. Pregnyl, Profasi, Pergonal, APL) can cause false positive results. There are also a number of diseases that cause hCG levels to rise. Alcohol, contraceptives, pain relievers, antibiotics, or hormone treatments without hCG will not affect the test result.

Your urine contains hCG and you are likely pregnant. Contact your doctor to confirm the result and for advice on what to do next.

There are some diseases that cause high levels of hCG, such as ectopic pregnancy or ovarian cysts.

The appearance of the control line (C) indicates that the test procedure was followed, a sufficient amount of urine was used and the test was functional.

This means that no hCG above the limit of detection (10mlU / ml) has been found in your urine and that you are probably not pregnant. If your period does not start within a week of the expected date, repeat the test. If you get negative results again and you still miss your period, please contact your doctor.

Limitations

  • This test provides a preliminary diagnosis of pregnancy. Do not draw any conclusions from this or make any medically relevant decisions without first consulting your doctor.
  • A number of diseases, such as trophoblastic diseases and some non-trophoblastic neoplastic diseases, such as some cancers, particularly breast cancer and lung cancer, cause elevated levels of hCG. As a result, a positive test result cannot be considered pregnancy as long as such clinical pictures are not excluded.
  • Highly diluted, low-density urine specimens may contain disproportionately low levels of hCG. It is advisable to repeat the test with fresh morning urine after 48 hours.
  • Very low hCG levels can be found in urine samples shortly after the egg cell has implanted. Since some pregnancies in the early stages are terminated by spontaneous abortions, it is advisable to collect the morning urine after 48 hours and repeat the test with it.
