title: Diagnosis of urticaria.
abstract: Acute urticaria do not need extensive diagnostic procedures. Urticaria activity score is a useful tool for evaluation of urticaria. Complete blood count, Erythrocyte sedimentation rate and C reactive protein are important investigations for diagnosis of infections in urticaria. Autologous serum skin test is a simple office procedure for diagnosis of auto reactive urticaria. Closed ball point pen tip is a simple test to diagnose dermographism.
