Low platelet distribution width means high platelet homogeneity, which is usually not a problem, and you can consult your doctor if you are not feeling well. Platelet distribution width mainly reflects the dispersion of platelet volume size and is expressed as the coefficient of variation (CV%) of individual platelet volume size. The normal value of this index is between 15% and 17%, with a low value indicating a relatively uniform platelet volume size. However, this indicator does not reflect the size and number of platelet volume, and needs to be combined with other indicators to make a comprehensive judgment. If the test result is simply a low platelet distribution width, usually there is no particular clinical significance, generally can not worry. However, if there are other abnormal indicators such as decreased platelet count, or if there are other uncomfortable symptoms, it is recommended to go to the hospital in time for examination and to clarify the cause of the disease in combination with other test results, and then carry out treatment.
