Abstrakt: Platelet concentrates undergo progressive changes during storage, such as a decrease in pH. Additionally, pH and lactate production showed the strongest correlation with platelet survival in posttransfusion viability studies. pH measurement is a straightforward method for evaluating the quality control of blood components in blood bank practice. Our aim was to compare three pH assessment methods for canine platelet concentrates. The pH values of the canine platelet concentrates were assessed on the first day of storage using a calibrated pH meter, a portable gas analyzer and pH-indicator strips. The results from the pH meter and portable gas analyzer measurements were similar. The pH indicator strips presented higher average values compared to the other more reliable methods evaluated, which could result in the use of inadequate blood components. In conclusion, it is recommended to implement pH measurements using a pH meter for quality control in veterinary blood banks.
