The subnormal responses to ADP, epinephrine, collagen, and arachidonate were found in 91%, 82%, 55%, and 34%, respectively. Nineteen patients had von Willebrand factor levels measured. Twenty-three subjects underwent repeat tests. Twenty-one of them were female (91%), with a median age and follow-up time of 37 years (IQR: 28–55) and 6 years (IQR: 3–12), respectively. Median ISTH-BAT bleeding scores at diagnosis and follow-up were 5 (IQR: 3–8) and 1 (IQR: 0–2), respectively. The common abnormalities were reduced responses to ADP combined with other agonists (83%). Twelve (52%) and five (22%) showed complete and partial platelet function recovery, respectively. None of the partial and non-recovery groups had a bleeding score over 4 at follow-up.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>Idiopathic mild platelet dysfunction was female-predominant and showed spontaneous symptom resolution after a long follow-up.
