Neonatal jaundice icterometer, a piece of transparent plastic painted in five transverse strips of graded yellow lines, is not recommended. This is hand held, portable and rechargeable but expensive. When pressure is applied to the photoprobe, a xenon tube generates a strobe light, and this light passes through the subcutaneous tissue.

The intensity of the yellow color in this light, after correcting for the hemoglobin, is measured and instantly displayed in arbitrary units. Any of the following features suggests pathological jaundice: The signs which help detect pathological jaundice
Eye-ring white eye-rings may consequently express vigorous health.
