Li L et al. - This method involves a multiplex PCR amplification of three fragments in the G6PD target sequence and a manual hybridization/detection protocol. The entire procedure starting from blood sampling to the identification of mutations requires less than 6 h. The diagnostic reliability of this reverse dot blot assay was evaluated on 207 pre-typed samples by using direct DNA sequence analysis in a blind study. The reverse dot blot typing was in complete concordance with the reference method. The reverse dot blot assay was proved to be a simple, rapid, highly accurate, and cost-effective method to identify common G6PD mutations in Chinese population.
