The paper by Erlwein et al. seems to have generated controversy about the different methods used in sample collection and PCR than Lombardi and colleagues. Although the authors used a positive control in their assays, this issue could be clarified if both the Erlwein and Lombardi groups exchanged blinded samples from their cohorts in order to determine the level of concordance.
