MTP test refers to urine microalbumin test, which is an indicator reflecting the change of glomerular basement membrane permeability. Abnormalities of this indicator can be seen in nephritis, kidney injury, etc. and can also be seen in over exertion, etc. Regardless of the circumstances, it is recommended to seek medical treatment in a timely manner. MTP test is urine microalbumin test, under normal circumstances, healthy human kidney basement membrane maintains normal filtration function, the content of albumin in the urine is minimal, the content of urine per liter of urine does not exceed 20mg. When renal pathology occurs, such as nephritis, nephrotic syndrome, kidney injury, etc., the basement membrane permeability increases, more protein is lost from the urine, and the MTP value increases, which represents kidney damage, and should be treated in time to reverse kidney function. Physiological conditions, such as strenuous exercise, fever, etc., can also cause abnormal values, which can be improved after rest, but regardless of the circumstances, it is recommended to consult a doctor in a timely manner to clarify the cause of kidney damage. MTP measurement varies within a day, so it is necessary to test 2-3 times in a row to improve the accuracy.
