Key Global Innovation is proud to introduce the first retail version of the fertility and pregnancy calculator. The Key Pregnancy Wheel is available at many retail pharmacies and retail department stores, and was developed by a medical doctor. Once only available to healthcare providers, it is now being brought to the general public. The wheel is essential to all women of reproductive age and medical and nursing providers. With this product, one has the essential tools needed to provide accurate and timely prenatal care. No other calculator has the ability to calculate dates of conception, fetal size, and delivery dates, while identifying the necessary laboratory tests that are required at critical times during the gestational period.
