Ortho clinical diagnostics (ortho) has determined that negatively biased results may occur when processing citrate plasma samples using vitros chemistry products phyt slides. as a result, citrate plasma is being removed as a recommended specimen type for vitros phyt slides. internal testing by ortho confirmed negatively biased patient results using vitros phty slides for citrate plasma samples. the majority of the bias may be attributed to the dilution effect of the liquid anticoagulant in the citrate plasma tubes with the sample. serum and/or heparin plasma samples obtained from the same patients did not exhibit biased results. the average negative bias observed using citrate plasma samples when compared to serum samples is approximately 18% across the phyt reportable measuring range of 3.00–40.00 µg/ml (11.88–158.40 µmol/l).
