The complete blood count (CBC) with differential is one of the most common laboratory tests performed today. It gives information about the production of all blood cells and identifies the patient's oxygen-carrying capacity through the evaluation of red blood cell (RBC) indices, hemoglobin, and hematocrit. It also provides information about the immune system through the evaluation of the white blood cell (WBC) count with differential. These tests are helpful in diagnosing anemia, certain cancers, infection, acute hemorrhagic states, allergies, and immunodeficiencies as well as monitoring for side effects of certain drugs that cause blood dyscrasias. Nurses in the perianesthesia arena are frequently challenged to obtain and evaluate all or parts of the CBC as a part of the patient's preoperative, intraoperative, and postoperative assessments. An enhanced understanding of this laboratory test is essential to providing quality care.
全血细胞计数（CBC）及分类是当今最常见的实验室检查之一。它能提供有关所有血细胞生成的信息，并通过评估红细胞（RBC）指标、血红蛋白和血细胞比容来确定患者的携氧能力。它还通过评估白细胞（WBC）计数及分类提供有关免疫系统的信息。这些检查有助于诊断贫血、某些癌症、感染、急性出血状态、过敏和免疫缺陷，以及监测某些导致血液系统异常的药物的副作用。围麻醉期的护士经常面临挑战，需要获取并评估全部或部分CBC结果，作为患者术前、术中和术后评估的一部分。增强对这项实验室检查的理解对于提供优质护理至关重要。
