概括

血氨分析可以在未立即处理的样本上进行. 在室温下保存样品长达两小时不会导致健康个体的错误升高结果.

科学领域:

临床生物化学临床生物化学
实验室医学实验室医学

背景情况:

建议立即处理和冷却用于氨分析的血样本,以防止体外代谢和错误的升高结果.
拒绝不合适的样本可能会延迟超氨血病的诊断和治疗.
目前的指导方针建议分析和报告未在理想条件下采集的样本.

研究的目的:

为了研究在控制室温下储存和延迟处理对血氨分析的影响.
为了确定非理想的样本处理是否会影响氨的结果的解释.

主要方法:

从11名健康志愿者收集了血液样本,并将其放入EDTA管中.
样品要么立即冷却,要么在室温下储存.
在10分钟间隔分析室温样本,长达2小时,使用罗氏氨 (NH3L2) 方法进行分析.

主要成果:

基线室温氨水平略高于冷却样本.
血氨在室温下每分钟增加0.09μmol/L,在2小时后达到30μmol/L.
在健康受试者中,没有结果超过50μmol/L的参考范围,防止错误的超氨血病诊断.

结论:

这些发现支持现有的指导方针,建议接受血样本用于氨分析,即使在不理想条件下处理.
实验室可以接受在室温下存储的样品长达2小时,而不会影响健康人群中超氨血的诊断准确性.

Sample Handling

Transportation of samples from the collection point to the laboratory, as well as storage and preservation techniques, are crucial for maintaining sample integrity and ensuring accurate and reliable test results.
Samples should be transported carefully from collection points to the laboratory. They should be properly sealed and clearly labeled to prevent cross-contamination. To preserve the sample integrity, optimal temperature conditions during transport are essential. This could involve using...
