Protocolo diagnóstico de las orinas de color rojo

Abstract

Red urine is commonly caused by hematuria, which is the presence of more than three red blood cells per high-power field on a microscopic urinalysis. A reactive strip allows for detecting it mainly in an outpatient setting with a high degree of sensitivity; it must be confirmed with a microscopic examination. It should be distinguished from pigmenturia, which is the presence of substances such as myoglobin in the urine which confers a similar color. Among the most frequent causes of hematuria are tumors, urinary tract infections, and lithiasis. Glomerular diseases must also be considered in the differential diagnosis.
