The presence of glucose can be detected with Benedict's reagent.

Benedict's reagent is prepared by mixing 100 g of anhydrous sodium carbonate, 173 g of sodium citrate and 17.3 g of copper(II) sulfate pentahydrate.

All reducing sugars, a list that includes glucose, can be detected using Benedict's reagent.

The test consists of dissolving the sample that needs to be tested for glucose in water. A small amount of Benedict's solution is added to the test solution and the mixture is placed in a water bath for around 5 minutes. If glucose is present in the sample the color of the solution changes color from blue to brick red.
