How does a home ovulation test work?
When a woman is about to ovulate, her body releases a large amount of a hormone called L.H. (Luteinising Hormone). L.H. is always present in your urine but the levels increase (surge) in the middle of your cycle, causing you to release an egg from the ovary, this process is called ovulation. If the L.H. surge is present, ovulation is likely to occur in the next 24 to 48 hours.
These ovulation tests detect the L.H. surge by measuring the amount of L.H. in urine.
