BCR2 is used to adjust the PMT-HV and indicates problems with the PMT and excitation.
• BCR2-D is a dilution of BCR2 with BCR1 and shows the functionality of the pipetter, the pipetter
precision and general problems with the liquid handling.
• AB3(CO) is determined using the measuring cycle for heterogeneous assays. These values are
the basic values used for calculating carryover.
• iSAP is a model assay based on streptavidin beads. iSAP facilitates the evaluation of the
complete LFS (liquid flow, magnet, capturing, detection) in a routine assay.
• Carryover is the measurable influence on the assay performance and is the consequence of
carryover of beads into the measuring cell in this case.
