Are test kits accurate?
If you’re trying to get pregnant, ovulation kits are sometimes recommended as a way to track your most fertile days.
The most popular tests are the type which test for the LH surge that triggers egg release. Obviously, if you identify the LH surge, you should be able to work out when your fertility will be at its peak and time having sex accordingly. If you have unprotected sex within 24 to 48 hours after the LH surge, your chances of becoming pregnant are at their highest.
Another type of test, the two-hormone fertility monitor test, also measures the amount of oestrogen in the urine. So, you get an advanced warning that ovulation is likely to happen imminently due to the rising levels of oestrogen, and you can also pinpoint the LH surge when it occurs.
Ovulation strips which can be used to test for LH surge are also available from chemists. These are similar to the type of strip used in a more sophisticated kit but don’t work with the kits; they are designed to be used alone.
