What would observe Benedict's solution is added to the blood plasma, glomerular filtrate, and urine of a norma?

• What would observe Benedict's solution is added to the blood plasma, glomerular filtrate, and urine of a normally functioning human, with a normally functioning kidney. Like would the results be positive or negative, and what would the intensity of the colors be?

• Answer:

  Benedict's solution is used to test for the presence of reducing sugars, (disaccharides, monosaccharides, lactose, maltose and by metabolic process alpha hydroxy-ketones. The higher the level of ketones or the other reducing sugars mentioned above, the solution turns red, green or yellow after being heated. If it remains clear, there are none of the reducing sugars or ketones present. It doesn't detect starches. It's used primarily to test urine for ketones, and thus determine diabetes (in conjunction with a hemoglobin A1c test) and blood glucose levels.
