High-quality specimens are essential for accurate laboratory results. Preanalytical errors due to issues, such as hemolysis, microclotting, and insufficient specimen volume, account for 60%–70% of laboratory errors and frequently result from improper blood collection techniques or negligence during the collection process. Therefore, standardized blood collection guidelines and continuous education are required. In Korea, standardized venous blood collection procedures have not yet been fully established, highlighting the need for an evidence-based protocol tailored to local requirements. The venous blood collection guideline presented here was adapted from international standards to conform to globally recognized practices and address the Korean clinical context. The guideline, developed by the Korean Society for Laboratory Medicine, outlines the critical steps in venous blood collection, from patient identification and consent to post-collection handling. Practical recommendations are provided for medical students, doctors, nurses, and medical technologists. The guideline addresses specific considerations for pediatric and older patients, as well as individuals undergoing blood culture tests, with an emphasis on minimizing errors and promoting the safety of patients and medical staff. The guideline includes practical tools, such as checklists and detailed information on sampling devices, to facilitate implementation. This initiative would help standardize blood collection practices, improve specimen quality, and enhance patient care by ensuring accurate laboratory results in clinical settings.

高质量标本对实验室检测结果的准确性至关重要。由于溶血、微凝血、标本量不足等问题导致的检验前误差占实验室总误差的60%-70%，这些误差往往源于不当的采血技术或采血过程中的疏忽。因此，需要标准化的采血指南和持续的教育培训。在韩国，标准化的静脉采血流程尚未完全建立，这凸显了制定符合本土需求的循证规范的必要性。

本静脉采血指南由韩国检验医学学会制定，在借鉴国际标准的基础上，结合全球公认的实践和韩国临床实际情况。该指南详细规定了从患者识别、知情同意到采血后处理的各关键环节，为医学生、医生、护士和医学技术人员提供了实用建议。指南特别关注儿科患者、老年患者以及血培养检测人群的特殊考量，重点在于减少差错并保障患者和医务人员的安全。

为便于实施，指南还提供了实用工具，包括核查清单和采样设备的详细信息。这一举措将有助于规范采血操作、提高标本质量，并通过确保临床检测结果的准确性来提升患者照护水平。
