Patient Question:Disease:Due to the blood routine of young children. Description of the disease:Hello teacher, my son’s 6-month physical examination blood routine found many indicators are not normal, platelets only 65. Hope to provide help:Is the problem big, how to face? Mao Guoshun, Department of Pediatrics, Fuyang People’s Hospital, replied: Routine blood tests generally include several aspects: red blood cell count and hemoglobin content, white blood cell count and classification, platelet count, and a number of other indicators to assist in the diagnosis of disease. The platelet count is most prone to laboratory bias, which means it is most likely to be inaccurate. Generally, if a test shows a decrease, the blood can be drawn again and retested, and the difference between the two results is not significant to be reliable. The role of platelets is to stop bleeding. A simple decrease in platelets without any other cause is generally a mild decrease from 50 to 100, which will not cause spontaneous bleeding, but will cause minor post-traumatic bleeding, a moderate decrease from 20 to 50, which will cause spontaneous bleeding, mainly manifested as skin petechiae and nosebleeds, and a severe decrease below 20, which will cause extensive and severe bleeding. Your child’s platelet 65, if the labs are reliable, is generally not at risk for bleeding, but the cause of the reduction needs to be identified, usually requiring a bone marrow test. Your child’s specific labs and clinical presentation are unclear, so only the above brief analysis can be made.
