In general, urine microalbumin may be more accurate compared to urine protein. Urine microalbumin can be an early indicator of damage to the glomerular filtration membrane. Urine protein refers to all protein components in urine, including albumin and other small molecule proteins, etc., while urine microalbumin refers to the albumin in urine, which can appropriately reflect the severity of nephritis. Therefore, urine microalbumin may be more accurate than urine protein. Under normal condition, the albumin content in human urine is relatively small, usually not more than 20mg/L. If it exceeds this range, then it means that the albumin content in urine is relatively high, which can be further judged by urine microalbumin level. If urine microalbumin is greater than 30mg/L, it usually suggests the presence of pathologic proteinuria, which may be related to nephritis and other diseases. However, no matter whether the urine microalbumin or urine protein is elevated, it is recommended that the patient go to the regular hospital in time, improve the examination to clarify the cause of the disease, and then give targeted treatment or treatment under the guidance of the doctor.
