This is a study design question. There are times when singlet testing is more acceptable, but generally duplicate testing is the ‘gold’ standard. Ideally, duplicate vs singlet testing should be performed to demonstrate no significant difference between the two. This could be also be shown by testing some samples in duplicate and some in singlet. Please make an appointment to talk with one of our experts by phone at 800.790.2258 or 760.448.5397
