Proteinuria is the term used for protein in urine. A person's urine may be collected as a random or timed urine sample. The normal protein level in a random sample ranges from 0 to 8 milligrams per deciliter, while a 24-hour or timed sample should be less than 80 milligrams per deciliter every 24 hours, reports the National Institutes of Health.

A protein urine test may be used by a doctor to check for the levels of the protein called albumin in diabetics. People with diabetes can develop microalbuminuria, which is the excretion of small quantities of urinary albumin, relates WebMD. In diabetics, microalbuminuria can be an early symptom of diabetic kidney problems, reports the Mayo Clinic. High levels of urine protein can also be caused by other medical problems like heart disease, dehydration and pregnancy.
