Les résultats pour les tests de diabète sont incorrect
Common issues with incorrect diabetes test results on the Mindray BA-88A include interference from carbamylated hemoglobin (CarHb), which can falsely elevate HbA1c results when using ion-exchange HPLC. CarHb has a similar charge to HbA1c and can overlap its peak during analysis. Additionally, system errors such as abnormal temperature, faulty sensors, blocked fan, or damaged filter wheel may prevent the test from running properly. These errors are displayed via dialog boxes and sound alarms, and are logged with details for troubleshooting.
