All blood samples were collected in EDTA tubes. Guidelines Upcoming Special Issues. This trend has lead to the development and approval of a number of diagnostic assays For reviews of these assays, see Constantine and Zhao, Detection of the resulting fluorescence collectively provides an immediate real-time quantification of the PCR process.

Review summary M Correa Posted on Dec 08 at 7: The fluorescence counts were converted into VL measure by the analyzer Abbott, a ; Abbott, The Abbott m RealTime System provides automation from bar-coded laboratory tube through patient result, creating an efficient workflow for your laboratory. In addition, abbottt precision of the methods could also potentially explain some of the discordant results.

It is unclear at the moment the source of the discrepancies.

The Abbott m 0. Short Communication Open Access.


Bland-Altman analysis of the quantitative results. Ann Jose ankara escort. 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 plot to the left represents the distribution of the VL from the Abbott method assay and the plot to the right represents the distribution of VL from the Roche assay. This automation enables laboratorians to interface where their skills best contribu In this configuration, signal is not created by probe hydrolysis but by separation of the probe from quencher oligonucleotide.

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 Finally, the NA was released using an elution buffer.

This study was approved by the Institutional Research Board under the protocol number of H However, a relative significant percentage An internal control was added into abbottt samples preparation procedure. 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. Various intrinsic factors including the gene target, LOD, input volume and different precision of the methods and variations in HIV-1 subtypes could potentially explain some of the discordant results.

Digestion of the probe DNA separates the reporter dye from the quencher dye, making the reporter dye signal detectable.

Another common feature of these two assays is the use of realtime PCR as their underlying technology for the measurement of HIV- 1 viral load. Home Publications Conferences Register Contact. The results showed as. Be the first to review this product. Whether through new system software releases, innovative assay design or a constantly expanding mSystem menu, we are continuously evolving.

The solid line in the box indicates the median value and the ends of the whiskers indicate the minimum and maximum values. A total of paired plasma samples were tested in the same day by both methods Table 2. It m20000sp 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.

The Abbott method positively identified samples out of with the detectability of In addition, their principles in designing primers and probes are also different. All VL values were first transformed into m2000dp log10 format. Pharmaceutical Sciences Journals Ann Jose ankara escort.

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

Each data point represents one of the paired quantifi able plasma samples. 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.

The Bland-Altman analysis was used for the analysis of the concordance of the two methods Bland and Altman, 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.


The extracted NA was mixed with the amplification reagents before amplification with the mrt Abbott, abbptt ; Abbott, This method has now become a standard method for monitoring HIV-infected patients on antiretroviral therapy k2000sp the United States. Detection by real-time technology used two probes of different lengths: Abbott Molecular’s msp for sample preparation and the mrt for real-time amplification and detection are the cornerstones for this process. Four different sample extraction volumes 0.

Even though both the Roche and Abbott methods use the realtime PCR technology, the gene targets are different. Table 1 summarizes the assay characteristics of these two assays. Of ND Roche samples, 15 of them October 02, ; Accepted Date: J Antivir Antiretrovir 2: Can’t read the image? This automated system uses magnetic microparticles-based reagents for the purification of nucleic acid from the samples. Request Pricing Receive your quote directly from the manufacturer.
