Roman55 [17]
Although there should be choices in this question, many findings in the urinalysis can point out a serious illness as long as it is clinically correlated. The color of the urine such as tea-colored urine may be a sign of obstruction of the biliary tree such that in choledocholithases or stones in the common bile duct. The consistency of the urine such as when it is hazy may indicate infection or albuminuria. Sugars present in the urine may indicate diabetes mellitus. Increased WBC (or pus cells) and RBC in the urine may point to a urinary tract infection (pyelonephritis) or glomerulonephritis. A positive protein in the urine may indicate albuminuria characteristic of nephrotic syndrome.

This allows molten rock from beneath the earth's crust to reach the surface, forming a new part of the ocean floor
