Some ovulation tests only tell you whether your LH is above or below a certain threshold. When you take these tests, they'll give you a positive or negative result. Problem is, the average ovulation test doesn't work for about 1 in 10 of us. Threshold-based tests are designed around averages of what an LH surge “should” look like, but bodies are all different. At least 1 in 10 people surge at a level that typically isn’t detected by these binary positive/negative tests. People with low LH levels can end up seeing “negative” all the time… even if they are ovulating.
Unlike threshold-based tests, the Modern Fertility Ovulation Test will actually quantify your LH levels for you. They give you a numerical value of your LH, telling you where it falls within a range. We might be biased, but we love semi-quantitative tests, since they can give you a better idea of how your LH is changing over time, help you understand LH patterns, and can pinpoint your most fertile days.
Plus, we developed a free app that pairs with our Ovulation Test to help you more easily track your unique LH surge and better predict your fertile window.
