Droplet digital™ polymerase chain reaction (ddPCR™) is a unique digital PCR technique that allows for absolute quantification of nucleic acid samples. This technique operates on the basis of amplification within water-oil emulsion droplets and can detect very small quantities of target molecules, yielding extremely precise data. Here, we describe in detail a ddPCR procedure for multiplexed detection of two clinically relevant herpesviruses, HHV-6A and HHV-6B.
