34
Q

ketonuria

A

normal range: 0; ketone bodies in urine, excessive production of intermediates of fat metabolism, which may result in acidosis, possibly because of of uncontrolled diabetes mellitus, starvation, low-carbohydrate diet.

35
Q

bilirubinuria

A

bile pigments, normal: 0; increased levels of bilirubin in the urine as a result of liver damage or blockage of the bile duct possibly caused by hepatitis, cirrhosis of the liver or gallstones.

36
Q

glycosuria or glucosuria

A

glucose; normal: 0; high blood sugar levels to to inadequate insulin levels; or can result when active transport mechanisms for glucose are exceeded temporarily, pathological: uncontrolled diabetes mellitus, nonpathological: excessive carbohydrate intake.

37
Q

pH

A

normal urine pH is 4.5- 8.0, pH can be affected by diet or bacterial infection.
