Bial's reagent consists of 0.4 g orcinol, 200 ml of concentrated hydrochloric acid and 0.5 ml of a 10% solution of ferric chloride. [2] Bial's test is used to distinguish pentoses from hexoses; this distinction is based on the color that develops in the presence of orcinol and iron (III) chloride. Furfural from pentoses gives a blue or green color.

Manfred Bial (10 December 1869 – 26 May 1908) was a German physician who invented a test for pentoses using orcinol, now known as Bial's test. [1] Bial was born on 10 December 1869 in Breslau, the son of Max Bial. He was an assistant at the Kaiserin-Augusta-Hospital in Berlin. Bial died on 26 May 1908 in Monaco. [citation needed]
Estimated change in probability: Based on table above, a likelihood ratio of 2.0 corresponds to an approximately +15% increase in probability. Final (post-test) probability: Therefore, bulging flanks increases the probability of ascites from 40% to about 55% (i.e., 40% + 15% = 55%, which is within 2% of the exact probability of 57%).
According to the American Cancer Society, these rates have risen by 2% annually since 2011. “Early onset colorectal cancer (colon cancer in persons under age 50) is on the rise, but in absolute ...

SeHCAT is a taurine-conjugated bile acid analog which was synthesized for use as a radiopharmaceutical to investigate in vivo the enterohepatic circulation of bile salts. [2] By incorporating the gamma-emitter 75 Se into the SeHCAT molecule, the retention in the body or the loss of this compound into the feces could be studied easily using a standard gamma camera, available in most clinical ...
An example of a positive Seliwanoff’s test. Seliwanoff’s test is a chemical test which distinguishes between aldose and ketose sugars. If the sugar contains a ketone group, it is a ketose. If a sugar contains an aldehyde group, it is an aldose. This test relies on the principle that, when heated, ketoses are more rapidly dehydrated than ...
