Further examinations were done for 50 children whose PT\/aPTT abnormality persisted in repeated tests. Seventeen patients presented with isolated prolonged PT, twenty\u2010seven patients presented with isolated prolonged aPTT, and six patients with both prolonged PT and aPTT. Coagulopathy was found in 31 (30%) of the whole cohort, which was 60% of patients with persistent abnormal tests. The most common deficient factors were FXII (5.8%), FXI (4.8%), FVII (2.9%), FV (0.9%), FVIII (0.9%), fibrinogen with FVII deficiency (0.9%), and von Willebrand factor (vWF) deficiency (0.9%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>According to the results of our study in patients presenting with incidental PT and\/or aPTT prolongation, mild factor deficiencies are more common than expected. Mild coagulation factor deficiencies can be seen in patients without any bleeding history. There is often no evidence of bleeding in mild factor deficiencies, and their clinical significance is unknown.<\/jats:p>\n
