Creating Strong Platforms for New Innovations Currently, there are no point-of-care TB diagnostic tools at the stage of evaluation or demonstration that are sufficiently sensitive and specific for TB detection in both populations with and without HIV infection. Technical Support Needs The Xpert assay is a computer-based test. This article needs attention from an expert on the subject.

The sputum smear microscopy is easy to do tuberculoeis is very cheap and combined with chest X-rays has been used for a long time by TB control agencies worldwide. If that doesn’t help, please let us know.

GeneXpert MTB/RIF

The Scan Cartridge Barcode dialog box appears. Expert Rev Anti Infect Ther. The price of Xpert equipment and cartridges is a barrier for scaling up Xpert in many countries. Testing is standardized and requires only moderate laboratory infrastructure and training.

However, the numerous operational and programmatic requirements associated with the assay and its results cause implementation to be less easy than expected.

However, clinical staff members need to be sensitized to Xpertso that they properly use the results to inform treatment. The findings and conclusions in this paper are those of the authors and do not necessarily represent the official position of the Centers for Disease Control and Prevention, the United States Agency for International Development, or the U.


Since molecular beacons fluorescence only when they are bound to their targets, i. Training of Both Laboratory and Clinical Staff Training has focused on laboratory staff members who operate the machine and perform the assay.

Additionally, the USG supports research studying different implementation models and their potential impact on TB care and management programs, including transmission and mortality. Author information Article notes Copyright and License information Disclaimer.

To gfnexpert a copy of this license, visit http: There is still a need for high-quality microscopy, culture, and DST to monitor treatment and outcomes and to complete the susceptibility profile. Tuberculosis TB continues to be one of the greatest killers in the world due to infectious disease, claiming over 1. Archived from the original on April 7, Retrieved from ” https: Process only as many specimens at one time, as there are GeneXpert Dx System modules available to run the test!

When tubercuulosis this tag, consider associating this request with a WikiProject. When the test is finished, the light turns off. Delayed results reporting can lead to patients placed in respiratory isolation unnecessarily or put on ineffective therapies. Countries have tubercuolsis make decisions about where to place the test; clinicians have to learn to trust the test results; program managers must embrace the challenges of implementing a new technology; and policy makers must agree to invest with adequate funding for scale up.

Open the cartridge lid. Current MTB diagnostics methods require weeks to deliver a definitive result.

Positioning of Xpert machines in the country needs to balance available resources, national capacity building, and accessibility to persons suspected of having TB that would most benefit from the diagnostic test.

However, such techniques require expensive and sophisticated laboratory infrastructure and staff, and tubwrculosis can take weeks or months to obtain results.


GeneXpert MTB/RIF – Wikipedia

If so, how should they proceed? Conventional culture and drug-susceptibility testing [DST] are still required to complete the drug-resistance profile and to monitor treatment.

If the problem continues, please let us know and we’ll try to help. Because it is a new and expensive technology, many countries are placing their first machines in central- and regional-level labs to gain knowledge, build a cadre of staff who can provide technical assistance on the assay, and most importantly, test as many people suspected of having TB as possible. The need for fast and accurate TB diagnosis with indication for the drug resistance is greater than ever. Received Nov 9; Accepted Feb TB programs can garner other lessons learned from HIV programs, which have witnessed rapid implementation of new technologies and treatments.

Monitoring and Evaluation A robust monitoring and evaluation system needs to be put in place, including appropriate indicators and support for data collection, reporting, and analysis. Integrating Xpert into national laboratory strategies for both the public and private sectors and country plans for initial implementation, including identifying target groups, defining diagnostic algorithms, selecting appropriate sites, forecasting commodities, and developing an annual activity plan and budget.

Standard 2 of the International Standards for Tuberculosis Care states that all patients suspected of having pulmonary TB should submit at least two sputum specimens for bacteriological examination. SPC does not meet acceptance criteria, because the sample was not properly processed, or because PCR was inhibited.
