Plasma prothrombin fragment F1+2 levels in 40 healthy controls and 63 patients with bullous pemphigoid (BP), 20 with chronic urticaria (CU), 14 with atopic dermatitis (AD), six with cutaneous drug reactions (CDR), 20 with psoriasis, four with dermatitis herpetiformis (DH) and five with primary cutaneous T cell lymphoma (CTCL). The results are expressed as pmol/l, and the horizontal lines represent geometric means. F1+2 levels were higher in the patients with BP, CU, AD and CDR than in the normal controls, but normal in the patients with psoriasis, DH and CTCL.
