Waste Products in the Blood
Waste products are usually excreted by the kidneys. High levels of waste products in the blood may mean that the kidneys are not working as they should.

Serum Creatinine (CR): An indicator of kidney function
High levels of uric acid are also found in those with gout, arthritis and some metabolic disorders.
