Editing Glucose tolerance test (section)

==History==
The glucose tolerance test was first described in 1923 by [[Jerome W. Conn]].<ref>{{cite journal|author=Conn, JW.|title=Interpretation of the glucose tolerance test. The necessity of a standard preparatory diet|journal= Am J Med Sci |year=1940 |volume=199 |pages=555–64|doi=10.1097/00000441-194004000-00014}}</ref>

The test was based on the previous work in 1913 by A. T. B. Jacobson in determining that carbohydrate ingestion results in blood glucose fluctuations,<ref>{{cite journal | title=Jacobsen ATB. Untersuchungen über den Einfluss verschiedener Nahrungsmittel auf den Blutzucker bei normalen, zuckerkranken und graviden Personen. Biochem Z 1913; 56:471–94}}</ref> and the premise (named the [[Staub-Traugott Phenomenon]] after its first observers H. Staub in 1921 and K. Traugott in 1922) that a normal patient fed glucose will rapidly return to normal levels of blood glucose after an initial spike, and will see improved reaction to subsequent glucose feedings.<ref>{{cite journal|author=Traugott, K.|title=Über das Verhalten des Blutzuckerspiegels bei wiederholter und verschiedener Art enteraler Zuckerzufuhr and dessen Bedeutung für die Leberfunktion |journal=Klin.
