Urine hemosiderin (HS, Hd)

Hemosiderin (Hd) is an unstable ferritin polymer that is brown in color and dark urine in urine. When hemolysis occurs in the blood vessels, excessive free hemoglobin is excreted through the kidneys to form hemoglobinuria. A part of hemoglobin is reabsorbed by renal tubular epithelial cells and decomposed into hemosiderin in the cells, which is released from the urine as the cells fall off. Forming hemosiderin urine. This test reflects the presence of intravascular hemolysis in the body. The presence of hemosiderin in the urine indicates that the red blood cells in the blood vessels are severely damaged, and its significance is similar to that of hemoglobin in the urine. Basic Information Specialist classification: growth and development check classification: urine / kidney function test Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Normal value: no Above normal: negative: normal. Positive: Chronic intravascular hemolysis, paroxysmal nocturnal hemoglobinuria, autoimmune hemolytic anemia, severe muscle disease, etc. Tips: Do not exercise vigorously, maintain a good diet and work. The middle part of the urine is taken for inspection. Women in the menstrual period are not suitable for this examination. Normal value negative. Clinical significance Positive Found in chronic intravascular hemolysis, paroxysmal nocturnal hemoglobinuria, autoimmune hemolytic anemia, severe muscle disease. It is worth noting that in the early stage of acute hemolysis, hemoglobin may be present in the urine, and urine occult blood test (a urine test can be used to detect A positive, but because the renal epithelial cells are too late to take up hemoglobin and degrade, it has not yet formed rapidly. Hemosiderin urine, so this test can be negative. Positive results may be diseases: paroxysmal nocturnal hemoglobinuria, autoimmune hemolytic anemia considerations Before the test: Do not exercise vigorously, maintain a good diet and rest. At the time of examination: a part of the urine is discharged first to wash away the bacteria remaining in the urethra and the anterior urethra, and then the middle part of the urine is taken for inspection. Inspection process The urine of the subject was collected and detected by chemical methods. Not suitable for the crowd Not suitable for the crowd: women in the menstrual period.
