What is microalbumin?
Albumin, also known as microalbumin, is the primary protein found in the blood. When healthy kidneys expel waste from the blood, tiny filters control large albumin molecules from escaping the body in urine. Usually, just a trace of albumin, or none, will get through the filters. However, if the kidneys are damaged, more significant amounts of albumin may pass into the urine.
What is the purpose of this test?
Order this Microalbumin Urine Test, 24-Hour, which measures albumin levels in the urine over 24 hours to help screen for kidney disease. Slight traces of albumin in the urine may be one of the first signs of kidney disease. If kidney disease is detected early, an individual can seek treatment before it worsens. This test may also monitor disease progression and the effectiveness of the treatment.
What factors may cause elevated urinary microalbumin levels?
Many factors may cause elevated urinary microalbumin levels, such as:
- Blood in the urine (hematuria)
- Certain medications
- Fever
- Recent intense exercise
- Urinary tract infection (UTI)
- Other kidney disorders
