What does urinary microalbumin mean?

Microalbuminuria refers to the presence of low concentrations of albumin in human urine, which can indicate whether the kidneys are damaged. Microalbuminuria can be tested using either a random urine sample or a 24-hour urine collection. During testing, attention should be paid to diet; avoid consuming large amounts of protein-rich foods, ensure adequate rest, and refrain from strenuous exercise.
