Tests
This test measures the level of renin in your blood. Renin is an enzyme, a protein that speeds up certain chemical reactions in your body. It's made by your kidneys. When your blood pressure or sodium decreases or your potassium increases, your kidneys release renin. That's because renin also acts as a hormone (a chemical messenger in your bloodstream that controls the actions of certain cells or organs) to help control your blood pressure.

A total protein and albumin/globulin (A/G) ratio test measures the total amount of protein in your blood.

Tests
A urobilinogen in urine test measures the amount of urobilinogen in your urine (pee). Urobilinogen comes from bilirubin. Your body makes bilirubin during the normal process of breaking down old red blood cells. Your liver uses the bilirubin to make bile, a fluid that helps you digest food in your intestines. Some bile flows through your bile ducts (small tubes) from your liver directly into your intestines. The rest is stored in your gallbladder for when you need it.
