Performing QC analysis
Control materials are processed in the same manner as patient blood sample
(See chapter 4). To run a QC sample, scan the QC barcode (previously recorded
in the settings menu), and then load in any free position. The MINI-CUBE will
recognize a QC tube by the registered lot number, and will display an image on
the screen with a barcode label, whether the QC sample is manually entered or
barcoded, as shown in Fig. 5.2. The tube with a white cap indicates a Normal
level control while the tube with a black cap indicates an Abnormal level control.
