Rapid and reliable Rhesus D typing is crucial for blood donation centers. In instances of massive blood transfusion or reduced antigen expression, DNA-based phenotype prediction becomes mandatory. Our molecular typing approach involves an initial real-time PCR for the most common aberrant types in our region, (weak D type 1), (weak D type 2), (weak D type 3), and (DVII). For comprehensive coverage, Sanger sequencing of coding regions is performed in the case of PCR target-negative results. We evaluated the specificity and accuracy of these methods using the recently launched LightCycler PRO real-time platform. All findings demonstrated remarkable accuracy. Notably, the LightCycler PRO instrument offers a distinct advantage in data interpretation and integration via the HL7 interface. This study underlines the importance of including advanced molecular techniques in blood typing protocols, especially in scenarios where conventional serological methods may be insufficient.
快速可靠的恒河猴D血型分型对献血中心至关重要。在大量输血或抗原表达降低的情况下,基于DNA的表型预测变得必不可少。我们的分子分型方法包括对我们地区最常见的异常类型(弱D型1、弱D型2、弱D型3和DⅦ型)进行初始实时PCR。为了实现全面覆盖,在PCR靶点阴性结果的情况下,对编码区进行桑格测序。我们使用最近推出的LightCycler PRO实时平台评估了这些方法的特异性和准确性。所有结果都显示出了极高的准确性。值得注意的是,LightCycler PRO仪器通过HL7接口在数据解释和整合方面具有明显优势。这项研究强调了在血型分型方案中纳入先进分子技术的重要性,特别是在传统血清学方法可能不足的情况下。
