Urinary albumin clearance

Urinary albumin clearance is an adjunct test to check if glomerular function is normal. Under normal human metabolism, there is very little albumin in the urine, specifically no more than 20mg (<20mg/L) per liter of urinary albumin, so it is called microalbumin. If the microalbuminuria in the urine is found in the range of 20mg/L-200mg/L after the physical examination, it is a microalbuminuria. If the patient can go through the standardized repair of the nephron and reverse the fibrosis treatment, the kidney can be completely repaired. The ball, which eliminates proteinuria, shows negative (-) or (+-) urine urine protein. Basic Information Specialist classification: urinary examination classification: urine / kidney function test Applicable gender: whether men and women apply fasting: not fasting Tips: Check that you must not drink in the morning on an empty stomach or even water, because eating will affect blood sugar levels. Normal value The normal result is that the reference value is <50%. Clinical significance Abnormal results: increased ratio reflects glomerular dysfunction. When the microalbuminuria in urine exceeds 200mg/L, it should be noticed. At this time, it is proved that a large amount of albumin has leaked out from patients with nephropathy, and hypoproteinemia may occur. The development of nephropathy is only one step away from the irreversible period. Test urine protein positive (+) ~ (+++), if not treated in time, it will enter the uremia period. People who need to be examined: suspected to be dysfunctional glomeruli. Precautions Taboo before the test: Check must be on an empty stomach or even water in the morning, because eating will affect blood sugar levels. Requirements for inspection: Due to the increase in gastrointestinal contents after meals (especially after a full meal), various organs including the kidneys will be piled up to varying degrees, and the edge of the organ is not easy to display and information will be missed. The results of the examination are confused with the actual situation, so the patient should be reminded not to eat during the examination. Inspection process Two proteins of very large size in urine were determined and expressed as the slope θ of the logarithm of the relative clearance and the logarithm of the molecular weight. Usually enter the linear equation first, find the slope K of the line, check the three solution function table or calculate the θ angle. For example, K = (logC1-logC2) / (logX1-logX2), C1 transferrin clearance, C2IgM clearance, molecular weight of X1 transferrin, and molecular weight of X2IgM. θ>64° is good selectivity and <53° is non-selective. Not suitable for the crowd Inappropriate people: Generally, there is no suitable for the crowd. Adverse reactions and risks No related complications or hazards.
