Is a microalbumin level of 30 mg/L normal?

In general circumstances, microalbumin refers to urinary microalbumin. Whether a urinary microalbumin level of 30 mg/L is normal needs to be determined according to specific situations. If the level of 30 mg/L is temporary and there are no other abnormalities, it is generally considered normal. However, if the urinary microalbumin remains at 30 mg/L for a prolonged period or is accompanied by other symptoms, it may be abnormal. If discomfort occurs, timely medical consultation is recommended. Detailed analysis is as follows:

Under normal conditions, trace amounts of albumin exist in urine, with a normal range generally below 30 mg/L. A microalbumin level of 30 mg/L is considered to be at the upper limit of the normal range. If the test result is 30 mg/L without other abnormal symptoms, it is generally considered normal. It could be caused by factors such as intense exercise, prolonged standing, or concentrated urine. Once these triggering factors are removed and the body recovers to a normal state, urinary microalbumin levels usually return to normal.

If urinary microalbumin consistently exceeds 30 mg/L and repeated tests show abnormal results after excluding physiological factors, it may indicate early kidney damage. For example, in the early stages of diseases such as diabetic nephropathy or hypertensive kidney damage, urinary microalbumin levels may slightly increase. Additionally, if symptoms such as frequent urination, urgency, or painful urination are present, it may indicate a urinary tract infection. In such cases, the condition may be abnormal, and timely medical treatment at a hospital is necessary.

It is recommended to maintain a light diet and engage in appropriate physical activity daily to enhance immune function and resist viral invasion.
