Compare Our Ovulation Tests
It's important to compare the various brands and their published sensitivity levels. The sensitivity is measured in terms of how little Luteinizing Hormone (LH) they can detect in your urine. The lower the number, the more sensitive the test is to detecting LH.
LH is normally present in women at all times at fairly low levels (under 20 mIU/ml) although the amount varies greatly. When ovulation occurs, there is a surge in LH levels to somewhere between 20 mIU/ml and 100mIU/ml. Some ovulation tests with sensitivity levels of around 40 mIU/ml will detect ovulation later than others and can sometimes miss an LH surge.
A highly sensitive test is better, even if it detects LH at low levels, as long as the control line is set at around 30 mIU/ml. This allows the ovulation tests to provide an indication as to how the LH changes when tested on a twice-daily basis, through the strength or darkness of the test line. A highly sensitive test can therefore provide women with an indication of ovulation 36 to 48 hours beforehand, compared to 24 hours for less sensitive tests.
Because sperm can survive for up to 7 days in the fallopian tubes, it's worth knowing as far in advance as possible when you will ovulate. Our ARTG listed ovulation tests detect LH at levels as low as 10 mIU/ml giving women the feedback they require to understand when their LH levels change, much earlier than other tests on the market.
