What is the bili-ruler™?

The bili-ruler™ is a screening tool that was developed using advanced digital image processing and human centered design. It is a low-cost, noninvasive, accurate, and easy-to-use device to screen for newborn jaundice.

How does the bili-ruler™ work?

The bili-ruler™ is an icterometer that compares scientifically selected and precisely printed colors to the color of a baby’s blanched skin. Using the bili-ruler™ color that most closely matches the baby’s blanched skin color, the user can approximate the baby’s bilirubin level and determine the need for diagnosis and treatment of jaundice.

How does the bili-ruler™ compare to other bilirubin measuring methods?

The bili-ruler™ improves upon the original Gosset Icterometer which decreased in accuracy on deeper skin tones, was high-cost, and relied on inconsistent color shades.

The bili-ruler™ has a strong positive correlation with both transcutaneous and serum bilirubin measurements. Learn more here.
