When it comes to the indicator of urinary microalbumin, not to mention that the average patient will feel very unfamiliar, even medical workers in some specialties may not understand its specific significance. In fact, many patients with hypertension, diabetes, and kidney disease should also pay attention to this examination indicator. Why? Because this indicator is used well to see the patient's early kidney damage, today Dr. Zhang will give you a brief explanation, I hope you can read this article.
In recent years, urine microalbumin has attracted more and more attention, which mainly reflects the early damage of the kidneys. In medicine, urine microalbumin is called "urine microalbumin", which is a medium molecular protein secreted by the liver. Under normal circumstances, most of this molecular protein can not pass through the kidney filtration membrane, and a small amount can penetrate the membrane, and the filtered protein will also be completely reabsorbed in the near curved renal tubules of the kidney, so in the urine of healthy people, this protein is rarely present and fluctuates greatly. When the glomerular filtration membrane is damaged or the tubular resorption function is impaired, this protein will appear in large quantities in the urine. So, when this urine microalbumin exceeds the standard, can it be considered that the kidneys are damaged? Rigorously to tell you that this understanding is not entirely correct, because this protein fluctuates greatly in different individuals, so it is best not to use it as a measure of whether it is in a disease state.
So, the question arises again, since this indicator cannot accurately reflect the early damage of the kidney, what index can accurately reflect the early damage of the kidney? Dr. Zhang's advice is to check the urine microalbumin/urine creatinine, note that this is a ratio, and use urine microalbumin ÷ a ratio obtained by urinary creatinine.
Although urine microalbumin, as mentioned earlier, is affected a lot and fluctuates greatly, it is impossible to measure whether it is in a disease state by oneself. However, the ratio of urine microalbumin and urine creatinine can remain relatively constant. Because of this feature, the urinary microalbumin/urine creatinine ratio is a more accurate reflection of early kidney damage. Therefore, Dr. Zhang recommends that patients with hypertension and diabetes can pay attention to checking the urine microalbumin / urine creatinine (see the figure below) this indicator, because according to its value to judge whether hypertension, diabetes is not the patient's kidney has produced early damage, but also can be given the corresponding to the later symptomatic treatment and treatment, usually after giving the correct treatment, many patients can still return to normal, which also shows that the early damage to the kidneys has been improved, why not.
I hope that Dr. Zhang's explanation today will be helpful to everyone, and if you feel good, you can also forward it to more people to read, so that more people can benefit from it.
