Blood-direct InvaderPlus® as a new method for genetic testing

Aim: This study compared the efficiency of Blood-direct InvaderPlus® with existing methods for detecting genetic polymorphisms by using clinical samples, and to determine whether this new method can be used for future clinical studies. Materials & methods: We developed a new method, called Blood-direct InvaderPlus, for detecting genetic polymorphisms. Whole-blood samples were subjected to genetic analysis with the new method and also the conventional method. Results: The results obtained with the new method were consistent with those of direct sequencing. Blood-direct InvaderPlus was able to detect gene polymorphisms of UGT1A1*6, *27, *28, *60, VKORC1 -1639G>A, VKORC1 1173T>C and CYP2C9 *2 and *3 much faster than the conventional methods. Conclusion: Blood-direct InvaderPlus allowed accurate, simple and rapid detection of genetic polymorphisms.
