Determination of assay reproducibility. DNA was extracted from ten 300 µl replicate aliquots of whole blood from six healthy donors (A). WBTREC/ml was then calculated for five of these replicates in three donors (B). To examine the potential effect of a delay in sample processing, DNA was extracted from five replicates of a single sample at 1 h, 6 h and 24 h (C). WBLogTREC/ml was then quantified in all five aliquots for each time point (D). All plotted values are mean ± SD.
