OBJECTIVE: To investigate in-vitro haemostasis in subjects with symptoms suggesting a mild bleeding disorder.
DESIGN: A prospective study in which an extensive range of in-vitro tests were applied unselectively.
SETTING: Patients were referred from community-based practices and hospital outpatient services.
PATIENTS: Ninety-three consecutive patients were examined. Hospital patients with severe illness were excluded.
CLINICAL FEATURES: Patients presented with easy bruising (68%), epistaxis (12%), excessive operative bleeding (7%), menorrhagia (4%), haematuria (3%), dental bleeding (1%) and bleeding from other sites (5%). In no instance was the bleeding life threatening.
OUTCOME MEASURES: Results of laboratory tests for patients presenting with the symptoms of a mild bleeding disorder were compared with the results for a healthy reference group.
RESULTS: Abnormal results of in-vitro tests were found in 53% of the subjects. Thirteen per cent had a prolonged bleeding time, of whom the majority had abnormal results of other in-vitro tests. Von Willebrand's disease was diagnosed in 7% of patients, although only half of these had a prolonged bleeding time.
CONCLUSIONS: Abnormal results of in-vitro tests were prevalent among subjects with symptoms of mild bleeding disorder. Easy bruising was as powerful a clue as any other bleeding manifestation to the presence of an abnormal in-vitro test result.
