What type of factors can affect the performance of this technology?

The quantity and quality of the DNA sample represents the most common factor affecting the performance of this technology. While buccal swabs represent an efficient and non-invasive method for DNA collection, the quality and quantity of sample is dependent on how many cheek cells are collected onto the brush. Too little DNA can result in a phenomenon call test dropout in which only a partial disease or DNA profile can be generated for that sample. To avoid this problem please read our detailed collection instructions which are included in all kits.
