Detection of Thyroglobulin in Bloodstains as an Aid in the Diagnosis of Mechanical Asphyxia

CODEN: JFSCAS

Abstract

Mechanical forces applied to the neck region are known to release certain amounts of thyroglobulin into circulation. In this experiment, an attempt was made to detect thyroglobulin in bloodstains as an aid in the diagnosis of mechanical asphyxia. Experimental bloodstains containing thyroglobulin at concentrations of 1, 2, 5, and 10 μg/mL were prepared on a sheet of filter paper. Small pieces of bloodstains, measuring approximately 2.4 cm2 in area, were extracted with 0.1 mL of distilled water and the extracts were tested against an antihuman thyroglobulin serum by precipitation-electrophoresis. Bloodstains containing more than 1 μg/mL of thyroglobulin formed distinct precipitin lines for up to one month of storage, while bloodstains containing more than 5 μg/mL of thyroglobulin formed distinct precipitin lines for up to three months of storage. The present results suggest that the bloodstains can be utilized in the diagnosis of mechanical asphyxia.
