Ovulation cassette tests

Sensitivity of ovulation tests: 
20miu/ml - High (One step ovulations tests)
30miu/ml - Normal 
40miu/ml - Low 

Successful fertilisation is most likely during a 24-36 hour period following the L.H. surge. Since this window is only open once a month and for a short period of time, being able to predict the L.H surge is very helpful when trying to become pregnant. One Step ovulations tests are with good price reliable and sensitive.
