19 Multivariable Algorithm Eliminate the guessing game Instrument-level processing corrects for optical system variabilityFilter design and manufacturing process minimized spectral cross-talkPrimary data reduction algorithm is fluorescence scale invariantNo more simplistic threshold methods for Ct calculationsInstrument-level processing – Each cobas z 480 analyzer is uniquely calibrated to account for system to system variability.The filter wavelength were optimized to minimize spectral crosstalk between the different filters.Scale invariant simply means that the algorithm is not dependent on big an optical signal is achieved - it's based on relative fluorescence increase and not some absolute signal increase.Ct calculations are not based on a simple crossing of a threshold value (which can be very arbitrary). Other methods use simple algorithms such as second derivative peaks to call a Ct value. With other systems, a technician is required to view curves of ambiguous results. The multivariable algorithm used in the cobas 4800 system accounts for a variety of signal artifacts such as late peaks, double humps and slow growth rates to produce results that are positive or negative with no grey zone.

This step typically takes 2 – 7 minutes.Load cobas x 480 – Loading of consumables, specimens, and reagents; everything required for the run including the work order. This step can take 16 – 30 minutes depending on the size of the batch; 24 tests vs 96 tests.Sample Preparation – Automated total nucleic acid extraction and isolation by the cobas x 480 instrument. This includes the making of the master mix and pipetting of processed specimen into the AD plate for Real-Time PCR. This is an automated step that enables the operator to walk away from the system and perform other tasks. The processing time will vary dependent on the specimen type as well as the batch size. Sample processing for a 24 test batch of swabs and urine specimens for CT/NG testing takes 102 minutes and a batch of 96 samples will take approximately 167 minutes.Unloading of the cobas x 480 analyzer takes approximately 5 – 8 minutes and takes place in parallel with the start up of the cobas z 480 analyzer.Transfer to cobas z 480 – At the completion of sample processing the operator places a seal on the completed AD plate and transfers the plate to the cobas z 480 analyzer. Typically sealing the plate and loading the plate in the cobas z 480 analyzer will take 1 – 2 minutes.Amplification and detection is another walkaway step where the operator is free to perform other tasks in the laboratory. Amplification and detection is always the same regardless of batch size or specimen type; 86 minutes for CT/NG and 120 minutes for HPV.When the run is complete the operator removes the plate from the cobas z 480 analyzer and disposes of the plate. Typically this clean up step takes about 1 minute.Source: Argent Global Services

This unloading takes about 5 minutes, then the operator is able to begin loading the next run. The cobas x 480 instrument only requires daily maintenance every 24 hrs., so no maintenance or cleaning is required between runs. The internal clock on the cobas x 480 instrument will track the time for maintenance and can be seen on the status screen of the system software.Source: Argent Global Services, 2012

It is just as important to compare cycle time with walk away time. Longer the cycle time can create longer walk away time. Sounds good, but that means the time to result is longer as well.This slide demonstrates the importance of comparing all aspects of testing.The cobas HPV Test combined with the cobas 4800 system automation provides efficiency in total cycle time which will impact your time to results. This system has the shortest cycle time with the least amount of hands on time allowing for the operator to be free; attending to critical lab functions 90% of the time.cobas HPV testhc2 HPV testCervista hrHPV test# of Reportables948848Hands-On Time (min.)33.17149.02129.01Total Cycle Time (min.)299.71416.5476.64Walk-Away Time (% of Total)90%62%66%Source: HPV Comparison Study; Argent Global Services, 2010
