Definitions of HELLER'S TEST
Sort: Oldest first
1. For albumin: nitric acid is poured very carefully down the side of a test-tube containing urine; the fluids do not mix, but at the place where they touch a white disc appears if albumin is present. 2. For blood: a strong solution of caustic potash is added to the suspected urine and heated; a precipitate of earthy phosphates is thrown down which is of a red or reddish brown color if blood is present. 3. For sugar: Moore's test.
