False-Positive Alkaloid Reactions

Journal of Pharmaceutical Sciences, 1980
A variety of nonnitrogenous oxygenated compounds gave false-positive alkaloid reactions with Dragendorff's spray reagent. These compounds reacted positively if the oxygen function and the β-carbon bonded to the oxygen had high electron density. Thus, aldehydes, ketones, lactones, ethers, esters, epoxides, and peroxides with an ethylene bond or free ...

Biologic False-Positive Reactions for Syphilis

JAMA: The Journal of the American Medical Association, 1968
To the Editor:— The problem posed ( 203 :996, 1968) regarding a 54-year-old housewife with a reactive fluorescent Treponemal antibody test merits an expanded discussion particularly of the possibility of a biologic false-positive (BFP) reaction.

STUDIES ON SIGNIFICANCE OF BIOLOGIC FALSE-POSITIVE REACTION

Journal of the American Medical Association, 1957
• The Treponema pallidum immobilization test, a specific means of diagnosing the biologic false-positive reactor, will separate syphilitic from nonsyphilitic patients, within minor limitations. However, the diagnosis of biologic false-positive reactor raises significant questions concerning the patient.

FALSE-POSITIVE REACTION FOR ACETONURIA

Journal of the American Medical Association, 1959
ABSTRACT To the Editor:— While testing, with phenolsulfonphthalein (PSP), the renal function of a patient with well-regulated diabetes mellitus, a strongly positive reaction for acetonuria was noted. This false-positive reaction was noted with the conventional test for acetone, using sodium nitroprusside, as well as with Acetest tablets (Ames Co.) and ...
