用于前列腺特异抗原 (PSA) 检测的指尖血液采集是传统静脉血液采集的可行替代方案. 这种方法提供了可比的准确性和稳定性,可能增加参与前列腺癌查计划.

科学领域:

泌尿器科泌尿器科泌尿器科泌尿器科
临床诊断临床诊断临床诊断
公共卫生公共卫生

背景情况:

目前的前列腺癌 (PC) 查依赖于前列腺特异性抗原 (PSA) 测试,风险评估和MRI,通常使用静脉血液抽取.
由于资源限制,医疗保健专业人员采取静脉血液样本可能会限制参与基于人口的查.

研究的目的:

评估使用指尖采样毛细血管血液用于PSA测定的可行性.
为了比较毛细血管血液PSA测量与传统静脉血液样本.
评估PSA测试的毛细血管血液采集的稳定性和患者舒适性.

主要方法:

对196名年龄在40至75岁的男性进行前性研究.
使用相同的分析方法从毛细血管和静脉血液同时测量PSA.
评估一个星期在室温下样本的稳定性.
用数值疼痛尺度评估患者报告的不适.

主要成果:

毛细血管和静脉PSA测量之间没有发现显著差异.
毛细血管血液样本在没有立即离心的情况下保持稳定长达7天.
患者报告的疼痛得分很低,在毛细血管 (1.52/10) 和静脉 (1.61/10) 收集 (p=0.27) 之间没有显著差异.

关键词:

毛细血管血液中的血液.基于人口的查.前列腺癌是什么意思前列腺癌是什么意思前列腺特异性抗原前列腺特异性抗原根据风险调整的查.
