Low platelet distribution width should pay attention to whether there is any abnormality in other tests, if other tests are normal, then pay attention to regular rechecking; if there is abnormality in other tests, then it is necessary to pay attention to go to regular hospitals to seek professional diagnosis and treatment and carry out appropriate treatment. Low platelet distribution width indicates that the size of platelets is uniform, generally speaking, the clinical significance of this indicator alone is not significant and does not require special treatment, patients do not need to worry about it, and pay attention to the follow-up regular review. If the width of platelet distribution is low and there are other abnormalities in other tests, such as the reduction of red blood cells, white blood cells and platelets at the same time, and the bone marrow morphology test suggests that myeloproliferative hypoplasia, etc., this situation requires a high degree of suspicion of bone marrow hematopoietic failure, and it is necessary to pay attention to immediately go to the hospital to seek professional medical consultation and treatment, and carry out the appropriate treatment. Therefore, when patients find that the width of platelet distribution is low, it is recommended that they consult a specialized doctor in the hospital to see if they need to further improve other related examinations and make a comprehensive assessment with other examination results.
