Yes, the Keller-Killiani test can give a positive result with digoxin. This test is specifically designed to detect the presence of cardiac glycosides, such as digoxin, in a sample. A positive result indicates that the substance is present, which is consistent with the pharmacological effects of digoxin. However, it is important to confirm with more specific assays, as false positives can occur with other substances.
Borax is used in the Schotten-Baumann reaction to identify anthraquinone glycosides because it reacts with the anthraquinone to form a precipitate. This reaction is specific for anthraquinone glycosides and does not occur with other types of glycosides.
Borntrager's test is a chemical test for the identification of anthraquinone glycosides. Here anthraquinone glycosides are four type which O, N, S, C, and borntrager's test is use for O glycosides and modify borntrager's test use for C glycosides In this test boil test sample with 1ml of sulphuric acid in a test tube for 5min,filter while hot. Cool the filtrate and shake with equal volume of dichloromethane or chloroform then separate the lower layer of chloroform and shake it with half volume of dilute ammonia. A rose pink to red colour is produced in the ammonical layer. In some cases the anthraquinones may not answer for borntrager's test due to it's reduced form....in that time ferric chloride is used.......this test may called modified bontrager's test.........

Adderall will test positive for amphetamine. It is an amphetamine therefore it will test positive for such.
Will test positive for Benzodiazepines
if montoux test is positive
What is false positive in widal test
does cyclobenzaprine test positive for cocaine?
There is no false positive pregnancy test result. If it has ever been positive, then it is positive.
will you test positive for oxycontin and opiates if you are taking both
Identification tests for saponin glycosides include foam test (formation of stable foam when shaken with water), hemolytic test (lysis of red blood cells), and Lieberman-Burchard test (formation of red color with acetic anhydride and concentrated sulfuric acid). Additionally, thin-layer chromatography and spectroscopic methods can be used for further confirmation of saponin glycosides.
If it's a pregnancy test the answer is no, A test can come back negative even though its positive. But if it's positive, it's positive 99% of the time.
