Unsuspected haemophilia in children with a single swollen joint

Description: A clotting screen should always be performed in a child with a swollen joint, even if there is a history of minor trauma, to exclude underlying bleeding disorders. A prompt diagnosis of haemophilia will allow early arrest of bleeding by appropriate treatment, which will in turn minimise complications and reduce total exposure to blood products.
