Free to read VAN DEN BERGH TEST BiPhasic: Purple color develops immediately on addition of reagent. After experimental ligation of the bile ducts in dogs, two distinct processes are clearly manifested: first, the accumulation of the normally circulating bilirubin in the blood with its characteristic indirect Van den Bergh reaction for a period of several hours, and second, the subsequent appearance of the bile bilirubin giving the direct Van den Bergh reaction. Normal serum gives a negative van den Bergh reaction. - 79.143.182.159. Requires the addition of methanol to yield azobilirubin (reddish purple)= Indirect bilirubin.
