The present study was undertaken to assess the feasibility of whole dried blood spots to identify alpha-thalassemia-1 by PCR technique. Logistical constraints associated with sample collection and processing make the measurement of alpha-thalassemia-1 at community laboratories difficult. Dried blood spot samples provide a relatively convenient and minimally invasive means for collecting and transporting samples. We present Whatman 3 MM paper for spotting blood samples used for the first time for alpha-thalassemia-1 detection. Measurements of fresh EDTA whole blood and Whatman 3 MM dried blood spots prepared from venous blood were performed in 60 subjects. Whatman 3 MM dried blood spots results were precise and reliable. There was no actual difference in comparison to fresh EDTA whole blood samples. Whatman 3 MM dried blood spots for alpha-thalassemia-1 detection using the PCR technique showed no changes for 6 months.
本研究旨在评估通过聚合酶链反应(PCR)技术利用全干血斑鉴定α地中海贫血-1的可行性。与样本采集和处理相关的后勤限制使得社区实验室难以检测α地中海贫血-1。干血斑样本为样本采集和运输提供了一种相对便捷且微创的方法。我们首次展示了用于α地中海贫血-1检测的用于点样血样的沃特曼3MM滤纸。对60名受试者的新鲜乙二胺四乙酸(EDTA)全血和由静脉血制备的沃特曼3MM干血斑进行了检测。沃特曼3MM干血斑的检测结果准确可靠。与新鲜EDTA全血样本相比,并无实际差异。使用PCR技术检测α地中海贫血-1的沃特曼3MM干血斑在6个月内无变化。
