In the paper
“In general, the colour produced when the Tollens reaction is performed on glucose in urine appears more slowly and in the lower concentrations can be seen to be less deep in shade than that produced from galactose in urine in the same con- centration.”

“The discrepancy between the description of the reaction by Tollens, and that of some later writers, so far as galactose is concerned needs to be clarified if the test is to be of any value in the investigation of galactosaemia”

In the paper
“Fructose and somewhat more slowly, glucose, under similar conditions, will give some crystals of the osazone, but these are different in form and slower in appearing than the galactose hydrazone crystals, and the appearance of crystals as described, within a short time of the completion of the preparation is a good indica- tion of the presence of galactose in the urine examined.”

In the paper
“According to Tollens, galactose under the same conditions gives first a yellowbrown colour, and glucose a similar one, and the precipitate whieh subsequently forms is dark violet in the case of galactose, dissolving in ethanol to a red-brown colour showing no absorption band, and yellowish red in the case of glucose dissolving in ethanol to a yellow-red colour which darkens and shows no band.”

Positive results with the mucic acid test can be obtained on much less than 100 ml of urine, but satisfactory results cannot be obtained on specimens from infants with galactosaemia.
“though positive results can be obtained on much less than 100 ml. of urine, it is impossible to get satisfactory results on the specimens obtainable from these infants.”

The need to decide whether a reducing substance in urine is galactose may arise in a hospital laboratory lacking chromatographic experience or equipment.

Diabetes mellitus must be considered in infants with a reducing substance in urine, so any galactose test must differentiate galactose from glucose.
“Diabetes mellitus, though also rare in infants, must of course also be con- sidered, and therefore any test for galactose must be able to differentiate this sugar quite clearly from glucose.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-09-28, under version 3 of the claim definition (prompt extract-v3).
A second model labelled each claim on 2026-09-28 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
