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

Your body might make too much or too little protein if you have certain health conditions.

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.

A Zika virus test looks for signs of the Zika infection in your blood or urine. Zika is a type of flavivirus, as is dengue fever and West Nile . Like those viral infections , Zika is usually spread by mosquitoes , especially in areas with tropical climates, such as parts of Central and South America, Africa, Mexico, and islands in the Caribbean and Pacific. Because Zika can enter bodily fluids such as blood, urine (pee), and semen, it can also spread through sex with an infected person or from a pregnant woman to her fetus.
