Kahn Med.|kɑːn|
The name of Reuben Leon Kahn (b. 1887), Lithuanian-born U.S. bacteriologist, used attrib. and absol. to designate a diagnostic test for syphilis devised by him in 1922, in which serum or spinal fluid that has been inactivated by heating is shaken with a suspension of antigen obtained from beef heart and the mixture examined for flocculation (usually after a period of incubation).
1922Jrnl. Amer. Med. Assoc. 9 Sept. 874/1 The clinical application of the Kahn precipitation test compares favorably in sensitiveness with the standard Wasserman reaction. Ibid. 873/1 In the serums examined from patients with late bone and joint involvement, the Kahn reaction again compares very favorably with the two Wasserman reactions. 1950R. R. Willcox Text-bk. Venereal Dis. ix. 115 As a verification test the Kahn performed at different temperatures..has not proved entirely satisfactory. 1953Med. Ann. LXXI. 7 Positive Wassermann and Kahn reactions may be given, for a time, by the serum of patients recovering from glandular fever. 1964King & Nicol Venereal Diseases vii. 95 Of the many flocculation tests available, the Kahn test has been the most widely used, but in recent years the Price precipitation test (PPR) has increased in popularity in Great Britain. |
