BACKGROUND:Uncontrolled preanalytical variables can reduce the accuracy and reproducibility of downstream analytical results from peripheral blood mononuclear cells (PBMCs). METHODS:PBMCs were isolated from EDTA and citrate-anticoagulated blood samples, obtained from healthy subjects and patients with inflammatory and infectious conditions. PBMC-derived RNA samples were examined for gene expression changes induced by extended blood pre-centrifugation delays at 4â¯Â°C and RT. We used Taqman RTqPCR to evaluate the combination of two target genes for their "diagnostic performance" in identifying EDTA and citrate-anticoagulated PBMC samples with extended pre-centrifugation times. RESULTS:We established the PBMC preanalytical score, a gene expression metric to asses the PBMC quality related to the pre-centrifugation delay at room temperature for different anticoagulants. The PBMC preanalytical score measurement can identify: CONCLUSION: The proposed PBMC preanalytical score may enable objective PBMC sample qualification for downstream applications, which may be influenced by blood precentrifugation delays.
