PROTEIN
Description
- 0 to 14 mg/dL
- 24-hour urine collection - < 80 mg
Clinical significance
- The protein test provides a rough estimate of the amount of albumin in the urine. Albumin makes up about 60% of the total protein in the blood. Normally, there will be no protein or only a small amount of protein in the urine. When urine protein is elevated, the condition is called proteinuria
- When Kidneys are functioning normally they reabsorb the filtered proteins and return it to the blood, when kidneys are damaged they become less effective in filtering, causing a detectable amount of protein to spill over in urine
- Proteinuria may occasionally be seen in healthy individuals. Healthy people can have temporary or persistent proteinuria due to stress, exercise, fever, aspirin therapy, or exposure to cold
- If a large amount of protein is detected on a urinalysis and/or if the protein persists in repeated tests, a 24-hour urine protein test may be used as a follow-up
- The 24-hour urine protein test is done if proteins other than albumin are being suspected to be released into the urine
