Detecting changes in skin color is challenging because there is such a wide range of skin coloration in all individuals. Subtle changes like skin blanching may occur gradually over time, or there may be a sudden onset. Blanching of skin is usually a localized reaction and may be a sign that the skin tissue is not receiving its usual blood supply due to swelling, cold, or other problems, such as insufficient blood flow through the vessels.

Diagnosis and Treatment
Doctors are continually developing tools for effectively measuring skin blanching in individuals with varying amounts of melanin pigment in the skin. Although a subtle symptom, blanching of the skin remains an important indicator of overall health. A comprehensive examination, history and physical are required and diagnostic studies such as laboratory tests may be necessary. Treatment will depend on the underlying condition.
