Discovering whether you are at risk of developing specific diseases once required going to a hospital for various kinds of time-consuming examinations. Now it can be done with a simple test conducted at home or at a drugstore.

A 43-year-old female company employee from Tokyo bought a genetic test kit in April to discover whether she is at risk for diabetes.

Her father had suffered from the disease and took insulin, and she had long worried about developing diabetes, too. Every time she underwent a health exam, she first checked her blood glucose levels.
