By measuring the luteinizing hormone in your urine these strips can make an accurate prediction of when you'll be ovulating. This is vital information when you're trying to conceive. A rise in LH signals the ovary to release an egg — so when your levels reach a certain threshold, it's safe to assume that ovulation will occur within the next 12 to 36 hours.
Simply immerse the strip in your urine with the arrow pointing downwards. After three minutes, remove the strip from the urine. After another three minutes you'll be able to read the results. The strip will indicate either Positive (ovulation within 24-36 hours), Negative (you're not ovulating) or test failed (try again).
You'll receive 20 strips made from environmentally friendly recycled wood pulp.
