Clxxxii. the Determination of Cholic Acids in Blood

MANY methods for the determination of bile acids in blood have been published. Most of them have been tested here and have all been found to give bad results, when small amounts of bile acids were added to the blood. This is due chiefly to two circumstances which interfere with the exact determination; one is the difficulty of separating the bile acids from other blood constituents, and the other is the lack of a specific reaction for the former.
