Van den Bergh reaction is a chemical reaction used to measure bilirubin levels in blood. [1] [2] More specifically, it determines the amount of conjugated bilirubin in the blood. The reaction produces azobilirubin. Principle: bilirubin reacts with diazotised sulphanilic acid to produce purple coloured azobilirubin. [3]
test—the so called Hyperbilirubinemia Test of van den Bergh. McNee says: "the most recent and probably the most important work of all" (on jaundice) ' ' is due to Hijmans van den Bergh,...
experimental proof of extra-hepatogeuous bilirubin. Van den Bergh in a case of traumatic sub-dural hsematoma found by his test that the bilirubin content of the fluid was 1-4000 (50 units), a figure equal to the content of pure bile. This furnishes a clinical proof.

Mar 3, 2016 · Van den Bergh Test for Bilirubin It is a specific test for for identificaion of increased serum bilirubin levels. Normal serum gives a negative van den Bergh reaction. Mechanism of the reaction: Van den Bergh reagent is a mixture of equal volumes of sulfanilic acid (in dilute HCI)& sodium nitrite. Principle: Diazotised sulfanilic acid reacts ...
Inga Marie Arvad Petersen (6 October 1913 – 12 December 1973) was a Danish-American journalist who was a guest of Adolf Hitler at the 1936 Summer Olympics and also had a romantic relationship with John F. Kennedy in 1941 and 1942.
Abstract. The significance of the various types of direct van den Bergh reaction is discussed, and it is emphasized that the so-called biphasic reaction is not due to the presence in the serum of two forms of bilirubin, but to the failure of strong solutions of azobilirubin to follow Beer's Law.
