A Fiber Optic sensor for determining the total cholesterol has been designed and developed. The Long Period Grating (LPG) sensor developed showed good stability and repeatable performance. The sensor also showed good linear response in the range of 500 ppm to 4000 ppm of cholesterol levels. This is highly desirable for a commercial cholesterol sensor as the level of cholesterol for normal humans ranges from 1400 ppm to 2000 ppm.
