The process to identify such biosignatures is called gene expression profiling, and it's done using microarray analysis. 确定这个生物特征的过程就是所谓的基因表达，通过微阵列分析实现。
The next step will be to study whether the microarray analysis can be applied in a more challenging clinical setting, such as an emergency room. 下一步就是要研究如何使微阵列分析应用到临床时间中，比如急诊室，这是一个很有挑战性的工作。
