Best chance of getting pregnant – with an ovulation test
Ovulation tests help you find out when you have the best chance of getting pregnant. It is during ovulation and the first 24 hours afterwards that the egg is most likely to be fertilised. Our ovulation tests help you identify your 2 most fertile days. As ovulation approaches, the level of LH (luteinising hormone) in the body increases. The test measures LH in urine and gives positive results at levels above 25 mlU/ml. An ovulation test is suitable whether you want to increase your chances of getting pregnant or if you want to better understand your menstrual cycle to help you avoid getting pregnant.

When should I use the ovulation test?
An ovulation test should be used a few days before you expect to ovulate. If you have a 28-day menstrual cycle, you should start taking the test from day 11. If you are unsure how to calculate your ovulation, use our ovulation calendar.


Test pregnancy early – with an early pregnancy test
The RFSU Early Pregnancy Test has a sensitivity of hCG 10 mlU/ml and can be taken as early as 6 days before a missed period. This test is a so-called ultra-early pregnancy test and can be used to test you at an early stage of pregnancy. These tests have a higher sensitivity where lower levels of hCG can be detected in the urine even before the expected period. Easy to use, the test can be done directly in the urine stream. Test stick with result window showing clear answer with one or two lines.
Difference between an early and a regular pregnancy test
You can use the RFSU Early Pregnancy Test as early as 6 days before your missed period, which is 5 days before your period is expected. In lab tests, 75% of women got a positive pregnancy result 5 days before their expected period. While 95% of women got a positive result at 4 days before their period, at 3 days before their period it was over 99% of women. If your result is a weak positive pregnancy test, it is recommended to test again 2 days later with morning urine. If you perform the test before your expected period and get the result ‘Not pregnant’, there is still a possibility that you are pregnant. In early pregnancy, the amount of pregnancy hormone normally increases very quickly.

Pregnancy test with week indicator
The RFSU Weeks Pregnancy Test has a smart week indicator function, so if the test result is pregnant, you will also find out which week of pregnancy you are in. The test is easy to interpret and shows clear results with lines. The test has 4 different test lines to show the number of weeks pregnant since fertilisation. Each week of pregnancy corresponds to one line (1-2 weeks, 2-3 weeks, 3-4 weeks, 4+ weeks). You count the number of lines to see the number of weeks of pregnancy passed. Test stick with an extra wide tip that makes it easier to take the test directly in the urine stream.
The RFSU Weeks Pregnancy Test is particularly suitable for those who want to detect pregnancy at an early stage, even before menstruation, and later want to confirm pregnancy by taking a new test after 1-2 weeks.
How early can I use a Weeks pregnancy test?
The RFSU Weeks Pregnancy Test can be taken already 4 days before your expected period. When you test early, at 3 days before your period, about 80-90% will normally get a positive result given that you are pregnant. The test has a sensitivity of hCG 25 mlU/ml. If you take the test at your expected period, the reliability is more than 99%.

Digital pregnancy test – which is easy to interpret
A digital pregnancy test measures the hormone hCG in the urine, just like regular tests. The difference is that the result is displayed as a clear text on a screen – for example, ‘Pregnant’ or ‘Not pregnant’. A digital pregnancy test therefore gives a very reliable result that cannot be misinterpreted, as long as you perform the test according to the instructions. The sensitivity of the test is hCG 25 mlU/ml and has a digital display that shows the result within 3 minutes. Test stick with an extra wide tip that makes it easier to take the test directly in the urine stream.
When can I take a digital pregnancy test?
You can start using RFSU’s Digital Pregnancy Test on the day of your period. The test has more than 99% coincidence.

Pregnancy tests in bulk – for frequent testing
RFSU also offers affordable pregnancy test kits for those who want to test at home in a simple and reliable way. Can be used from the day you expect your period. The sensitivity of the test is hCG 25 mlU/ml and has an accuracy of over 99%. The RFSU Pregnancy Test Stick is a pregnancy test with a result window that gives a clear answer with one or two dashes. While the RFSU Pregnancy Test Strips are easy-to-use test strips that you dip into a container of urine.
Difference between a pregnancy test with a stick and strips
The difference is how easy the test is to use. With strips, also called sticks, you need to dip the test into a container of urine but get a very affordable pregnancy test. Which is suitable for those who want to test themselves often. The test stick is easier to use and easier to interpret. The test is taken directly from the urine stream and the test stick has a result window that clearly shows the result with one or two lines.

When to take a pregnancy test?
Testing for pregnancy with a home test should be done based on your expected period. Most pregnancy tests are so-called standard tests with a sensitivity of hCG 25 mlU/ml. These can be used from the day you would get your period.
RFSU offers self-tests for all different stages of the journey towards pregnancy. Our self-tests are easy to use, have clear easy-to-read instructions and all tests are quality assured with high measurement accuracy. The test is easily done at home by peeing on a test stick or dipping it in urine and a quick and clear result appears within minutes. RFSU pregnancy tests are over 99% accurate from the day you expect your period and some can be used a few days before.
