The volume supplied for the FBC is insufficient to run the sample in closed mode. Can the QAP provide larger volume for the FBC sample?
The volume provided in the FBC sample is 1mL of stabilised blood. The FBC samples are commercially prepared samples which is compatible with all instrumentation. Increasing the volume of sample will also increase the cost of this module considerably and the QAP has considered this option in the past. As a study undertaken by Haematology QAP, in 2004, showed that the majority of instruments did not demonstrate a significant variation in results between open and closed modes, the QAP has decided to keep the volume at 1mL.
