Non-invasive pH measurement in BCSI platelet storage bags The pH in four platelet bags was tracked over time with the BCSI pH sensor and a blood gas analyzer. The figure shows the average pHs for 4 bags with error bars as standard deviations for both methods. The mean difference from the average pH by both methods was 0.045 (n=32, SD 0.058).
