The Abbott method positively identified samples out of with the detectability of Whether through new system software releases, innovative assay design or a constantly expanding mSystem menu, we are continuously evolving.

The Abbott mrt performed the automated amplification and detection process. Can’t read the image? This study was approved by the Institutional Research Board under the protocol number of H Fast Your inquiry will be delivered straight to the manufacturer. Each data point represents one of the paired quantifi able plasma samples.

Comparison of the mean VL with differences of the two methods using the Bland Altman plot showed rough symmetric distribution of the differences, indicating neither method is better than the other for measuring VL. Zbbott blood samples were collected in EDTA tubes.

Using the TaqMan analyzer, the sample extraction volume protocol is 0. Our data showed that these two methods are m2000p indistinguishable with a correlation coefficient of 0. Box and Whisker plot for the quantifi able plasma samples. The best fi t for the regression analysis is indicated by the solid line. However, this factor should not be the major contributing factor because a recent surveillance study at the University of Maryland Medical Center showed that about The number of samples within this range was These two assays share three common features 1 Additional reduction in the lower limits of detection LOD of HIV-1 RNA from the earlier version; 2 New primers and probes designs for recognition of the different viral subtypes and circulating recombinant forms CRFs ; and 3 Reduction in hand-on time by configuring the test near to full automation.

Comparison of HIV-1 Viral Load between Abbott m2000 and Roche COBAS TaqMan Methods

In addition, different precision of the methods could also potentially explain some of the discordant results. Even though both the Roche and Abbott methods use the realtime PCR technology, the gene targets are different.

Of ND Roche samples, 15 of them A total of paired plasma samples were tested in the same day by both methods Table 2. In this configuration, signal is not created by probe hydrolysis but by separation of the probe from quencher oligonucleotide. The fluorescence activity was converted into VL yields by the analyzer Roche, Following reverse transcription, the RNA: The Abbott m RealTime System provides automation from bar-coded laboratory tube through patient result, creating an efficient workflow for your laboratory.

The results showed as.

The Abbott m 0. Dual-labeled fluorescent probes for HIV-1 and HIV-1 QS-specific oligonucleotides were used, each labeled with different reporter dyes and a quencher dye. It should be mentioned that the genetic diversity of HIV-1 subtypes could present a significant challenge in the accurate VL monitoring of HIV-infected patients who carry non-B subtypes Damond et al. Consistently, comparison of the distribution and median values of VL between these two methods also showed similar median VL values but a slight wider distribution by the Roche method than the Abbott method was seen Figure 2.

However, comparison of the differences of VL measurements between the two methods by using the Bland Altman plot showed rough symmetric distribution of the differences and the log differences in Home Publications Conferences Register Contact.

Automation is the foundation for the clinical molecular laboratory to report patient results with confidence. Results of this study m2000sp unable to evaluate the potential differences between these two assays in this regard. Why request a quote through SelectScience? The Version 2 of the m open mode 0. Finally, the NA was released using an elution buffer.

Pearson correlation test was used to measure the overall correlation of the VL between the two methods. Differences in gene target, test sensitivity, input volume and their abilities to detect different HIV-1 subtypes could potentially explain some of the discordance. Of the ND Roche samples, 15 This trend has lead to the development and approval of a number of diagnostic assays For reviews of these assays, see M2000s; and Zhao, An internal control abboyt added into the samples preparation procedure.
