Reynolds' pentad is a collection of signs and symptoms consistent with obstructive ascending cholangitis, a serious infection of the biliary tract. It is a combination of Charcot's triad (right upper quadrant pain, jaundice, and fever) with shock (low blood pressure, tachycardia) and an altered mental status.{{cite journal |vauthors=Reynolds BM, Dargan EL | title=Acute obstructive cholangitis; a distinct clinical syndrome | journal=Ann Surg |date=August 1959 | volume=150 | issue=2 | pages=299–303 | pmid=13670595 | pmc=1613362 | doi=10.1097/00000658-195908000-00013}} Sometimes the two additional signs are listed simply as low blood pressure and confusion.{{cite book|last1=Teo|first1=Amir H.
