Microalbumin Urine Take a look at

Wholesome kidneys take wastes out of the blood however depart protein. Impaired kidneys could fail to separate a blood protein known as albumin from the wastes. At first, solely a small quantity of protein that’s too low to be measured with a regular dipstick could leak into the urine. This situation is called microalbuminuria. That is how the take a look at is learn:

  • Lower than 30 mg/L is regular
  • Better than 30 mg/L however lower than 300 mg/L known as microalbuminuria

It’s used to test for anemia. Anemia, a scarcity of oxygen carrying crimson blood cells, usually begins on the early levels of kidney illness. Anemia is treatable. A standard hematocrit (Hct) for a wholesome grownup is 38-45%. For an individual with CKD, the fascinating Hct is 33-36%.


Hemoglobin (Hb. Hgb) is the a part of the crimson blood cell that carries oxygen to the cells of the physique. Each hemoglobin and hematocrit are measured to test for anemia. 3 times the hemoglobin degree equals the hematocrit. A standard hemoglobin degree for a wholesome grownup is 12-15 g/dl.
