Microalbumninuria Test

Submitted on March 27, 2012

A Microalbuminuria test is a test for protein in urine. It measures the levels of albumin, which is a protein, in a urine sample.

Reasons for Microalbumninuria Testing

It is done to test for kidney damage. Protein usually stays in the body and does not normally appear in the urine. The presence of abnormal levels of protein (albumin) in the urine is an early sign of a condition called microalbuminuria, which causes kidney damage. People with diabetes are at greater risk of kidney damage (diabetic nephropathy).

People who have had diabetes for many years are recommended to have a microalbuminuria test at least once a year. This test will indicate whether a person is at risk of developing kidney disease, and will enable the medical caretaker to begin early treatment.

Other conditions which may lead to high levels of albumin in the kidney and subsequent kidney damage are high blood pressure, some lipid problems and certain immune disorders.


It is done by collecting a sample of urine. Normal urination is needed, and there is no discomfort.


You may be told to stop taking any medicines or drugs such as Oxacillin, Nafcillin, Lithium, Aminoglycosides, Acetazolamide, Salicylates, Sulfonamides, Tolbutamide or Penicillin G which may interfere with the results.

Test Results

What other The following conditions may interfere with the results of the test:

  • Dehydration
  • Strenuous exercise
  • Severe emotional stress
  • Urine which is contaminated with vaginal secretions
  • Urinary tract infections
  • If you have received any special dye (contrast media) which are needed for radiology exams, within a period of 3 days of the microalbuminuria test.

Normal or abnormal Results

The concentration of albumin in the urine may be affected by the concentration of water in the urine. Hence, along with albumin, the level of creatinine in the urine is also measured. The results are quoted as the ratio between albumin and creatinine.

When more than 300mg of albumin is present it is considered as albuminuria.

In case the level of albumin is abnormally high, health care providers usually repeat the test on a 24-hour sample.

Test Kits

This test was previously only available with healthcare professionals, but matters have been simplified and these days a home test kit is available. You can purchase one and mail the sample, for a professional evaluation, to the company. If the result is positive, your medical caretaker will prescribe specific medications and treatment to prevent further damage.
