Red blood cell distribution width is high
Introduction
Introduction The standard of red blood cell distribution width is 0-15%. If the value is higher than this value, the red blood cell distribution width is high, which is basically normal. The red blood cell distribution width variation coefficient is an indicator indicating whether the red blood cell size is uniform. The high value indicates that the red blood cell size is uneven, and Related factors, can not be based on this to determine what disease.
Cause
Cause
Basically, the variation coefficient of red blood cell distribution width is an index indicating whether the red blood cell size is uniform. The high value indicates that the red blood cell size is uneven, which is related to various factors, and it is not possible to judge the disease according to this. Also note that the increase in red blood cell distribution width index is mainly seen in acute lymphoblastic chemotherapy, megaloblastic anemia, slow granules, splenectomy and giant platelets, etc. for the deep symmetry of the lower limbs and the sense of vibration disappeared. Serious can have balance loss and walking obstacles.

Diagnosis: Clinical manifestations of megaloblastic anemia:
1. Anemia symptoms.
2. Digestive symptoms and tongue pain, color red, nipple disappeared, smooth surface.
3. Neurological symptoms, such as posterior bundle degeneration of the spinal cord, manifested as deep symmetry of the lower limbs and loss of vibration. Serious can have balance loss and walking obstacles. Changes can occur at the same time peripheral neuropathy and mental depression. Child patients can present with mental disorders and mental retardation.
Diagnosis
Differential diagnosis
1. High hematocrit: Hematocrit helps to understand the increase and decrease of red blood cells. When the absolute value of red blood cells is increased due to various reasons, the hematocrit will also increase accordingly. High hematocrit is found in patients who have been examined for blood after shock.
2, erythrocytosis - high viscosity: erythrocytosis - high viscosity syndrome is a more common disease in the neonatal period, due to increased red blood cells, blood viscous, slow blood flow, easy to cause poor perfusion and lack of tissue Oxygen and damage to the heart, brain, kidney and other organs can partially affect the long-term prognosis of the nervous system.
3, erythrocytosis: erythrocytosis refers to the number of red blood cells per unit volume of blood is higher than the normal limit. It is generally believed that adult male erythrocytes >6 million/mm3 and adult females >5.5 million/mm3 are erythrocytosis. Increased relative is seen in blood concentration; absolute increase is seen in high altitude life, fetal and neonatal, severe physical labor, severe heart and lung disease, and polycythemia vera.
