The ELISA (enzyme-linked immunosorbent assay) is a test which uses color change and antibodies to identify a substance. An indirect ELISA is one of three ELISA tests.
Urine varies in appearance, depending principally upon a body's level of hydration, as well as other factors. Normal urine is a transparent solution ranging from colorless to amber but is usually a pale yellow. In the urine of a healthy individual the color comes primarily from the presence of urobilin.

The normal color should be clear or perhaps the color of lemonade (just a slight hint of yellow that can't be seen easily).This is a serious condition.The medical community either overlooks the signs of dehydration or else ignores them completely.f your urine is yellow, you're dehydrated.
