This test uses a personal ovulation microscope to detect hormonal changes in the saliva. Because of hormonal changes, when a woman is due to ovulate a distinct crystal "ferning" pattern is present in the saliva. A drop of saliva on the lens allows you to identify if the ferning is present using a 60x magnification lens.
The Focus Saliva Ovulation Test is re-useable.
The test has been shown to be 98% accurate.
