The ovulation test measures the concentration of the ovulation hormone LH (luteinizing hormone).
24-36 hours before ovulation, the LH hormone rises significantly, and if you test with an ovulation test, your ovulation test will be positive when the hormone has increased due to ovulation.
You can recognize the positive ovulation test by the test line being as dark or even darker than the control line.
It is recommended to start testing for ovulation 2-3 days before the expected ovulation. Ovulation typically occurs 14 days before your menstruation starts. So, if your cycle is 28 days, you should start testing for ovulation on day 11 or 12 (day 1 being the first day of your last menstruation).
If you are unsure about the length of your cycle, it is advised to start testing on day 10 or 11 of your cycle.
Gravidtid Early Pregnancy Test Strip has a sensitivity to the pregnancy hormone hCG at 10 mIU/ml.
You can test with Gravidtid Early Pregnancy Test from 9 days after fertilization/5 days before expected menstruation.
We recommend testing with morning urine if you want to use an early pregnancy test before your expected menstruation, as the level of hCG 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 Gravidtid Early Pregnancy Test Strip.
When using an early pregnancy test and testing before the expected menstruation, the accuracy is lower. Clinical tests on most early tests show, for example, that about 70% of pregnant women will have 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 catch a chemical pregnancy - that is, a pregnancy that ended within the first few days after fertilization. In this case, you will have a faint positive pregnancy test that may become less apparent over the following days and possibly be completely negative on the day of expected menstruation.
Graviditetshormonet hCG stiger meget hurtigt, hvis du bliver gravid. Derfor er graviditetstests lavet til at reagere på et forhøjet hCG-niveau, som betyder, at du er gravid.
Graviditetstests har to antistofstreger. Den ene er kontrolstregen, som får farve, når den bliver dyppet i urin. Kommer kontrolstregen frem med farve, så ved du derfor også, at din test virker som den skal. Den anden streg kaldes teststregen, og denne streg får kun farve, hvis din urin indeholder den mængde hCG, som din graviditetstest har en følsomhed overfor.
De allermest sensitive tidlige graviditetstests vil blive positive, allerede når dit hCG-niveau er kommet over 5 mlIU/ml.
