Abstract

Abstract: Introduction: Coagulation tests are affected by many factors, such as age, race, and gestation. Although coagulation test results vary by ABO blood type, reference intervals of different ABO blood groups remain to be determined. This study aims to investigate the reference ranges of coagulation tests for different ABO blood groups in the Han population in South China. Methods: A retrospective study was conducted in the First Affiliated Hospital of Shantou University Medical College. In all, 9600 individuals aged between 20 and 79 years were included. Coagulation tests, including prothrombin time (PT), international normalized ratio (INR), activated partial thromboplastin time (aPTT), thrombin time, and fibrinogen, were performed. Results: There was a significant difference in PT, INR, and aPTT among ABO blood groups. PT and INR varied slightly between ABO blood groups. There was a higher aPTT value in individuals in the O blood group than in those in non‐O blood groups, in both males and females across the included age range. No differences were found in thrombin time and fibrinogen between the ABO blood groups. Conclusion: The study provides reference data on coagulation tests from ABO blood groups in South China. The established reference intervals specific to ABO blood type, sex, and age may improve clinical decisions based on coagulation tests. Abstract : The present study established age‐, sex‐, and ABO blood group‐specific reference intervals for coagulation tests. The individuals with blood type O had prolonged aPTT than those with type non‐O. APTT varied with age and sex. No differences were found between thrombin time and fibrinogen in the ABO blood groups.
