Sex- and age-based reference intervals for capillary complete blood count parameters among urban preschoolers in southeast China based on a large community population.

Background And Aim: Pediatricians commonly use the complete blood count (CBC) of capillary blood to evaluate health status, guide diagnoses, and determine treatment strategies. This study aimed to establish sex- and age-specific reference intervals (RIs) for 23 capillary CBC parameters for urban preschoolers in Fuzhou, Southeast China.
