Les examens de laboratoire en hématologie

Complete blood cell count (CBC) and coagulation screening tests are the most performed laboratory tests. These two assays must be done systematically in various occasions since many blood disorders can be pauci or asymptomatic, and every illness may lead to their disturbance. For these reasons these tests are described in this paper. Nowadays, the majority of CBCs are performed using eighteen parameters automatic counters. For pedagogic reasons, this load of parameters is divided into three parts: red blood cells (RBCs), white blood cells (WBCs) and platelets parameters and the alteration of each of these later are highlighted hereafter. Standard coagulation assays (aPPT, PT, and fibrinogen) are described and the clinical approach explained in this monograph.
