1850 - Parisian chemist Jules Maumené (1818–1898) develops the first “test strips” when he impregnated a strip of merino wool with “tin protochloride” (stannous chloride). On application of a drop of urine and heating over a candle the strip immediately turned black if the urine contained sugar.
An early method resembling urine test strips was devised by the French chemist Edme-Jules Maumené in 1850. Maumené impregnated a strip of wool with tin(II) chloride, added a drop of urine, and exposed it to a flame. If the urine contained glucose, the wool would turn black.

The first-generation devices relied on the same colorimetric reaction that is still used nowadays in glucose test strips for urine. Besides glucose oxidase, the test kit contains a benzidine derivative, which is oxidized to a blue polymer by the hydrogen peroxide formed in the oxidation reaction. The disadvantage of this method was that the ...

In medicine, dipsticks can be used to test for a variety of liquids for the presence of a given substance, known as an analyte. [1] For example, urine dipsticks are used to test urine samples for haemoglobin , nitrite (produced by bacteria in a urinary tract infection ), protein , nitrocellulose , glucose and occasionally urobilinogen or ketones .
