The Reid Index is a mathematical relationship that exists in a human bronchus section observed under the microscope. It is defined as ratio between the thickness of the submucosal mucus secreting glands and the thickness between the epithelium and cartilage that covers the bronchi. The Reid index is not of diagnostic use ''in vivo'' since it requires a dissection of the airway tube, but it has value in ''post mortem'' evaluations and for research.〔B. Karger, T. Fracasso, B. Brinkmann and T. Bajanowski. ''Evaluation of the Reid index in infants and cases of SIDS''. International Journal of Legal Medicine. Volume 118, Number 4 / August, 2004.
