本文对于血液病的尿检验作一介绍:一、与溶血有关的尿检验1.尿隐血试验:在急剧血管内溶血时,因红细胞在血管内破坏加速,即产生血红蛋白尿,使隐性试验呈阳性。在轻、中度的溶血病例虽有高胆红素血症,并不一定有血红蛋白尿。当大量溶血时(主量是血管内溶血),血浆中游离血红蛋白大量增加,产生血红蛋白血症。当血浆游离血红蛋白>130毫克%时,可出现血红蛋白尿,后者可通过尿隐血试验和分光镜检查而得到证实。
This article for the blood test of urine for an introduction: First, hemolysis-related urine test 1. Urinary occult blood test: in the case of rapid intravascular hemolysis, due to accelerated destruction of red blood cells in the blood vessels, that is, hemoglobinuria, so recessive test was Positive. In mild and moderate hemolytic cases although hyperbilirubinemia, hemoglobinuria is not necessarily. When a large amount of hemolysis (the main amount is intravascular hemolysis), a significant increase in plasma free hemoglobin, resulting in hemoglobinemia. Hemoglobinuria can occur when plasma free hemoglobin is> 130 mg%, the latter being confirmed by urine occult blood test and spectroscopy.
