Introduction
The GeneXpert® Edge is a molecular testing device designed to facilitate testing and treatment at the point of care, particularly in resource-limited settings. It is not available in all countries, including the United States.

Critical Need in Resource-Limited Settings
Conventional testing networks often lead to delays in clinical decision-making due to sample preparation and transportation times, multiple days between testing and diagnosis, and high rates of loss to follow-up. The GeneXpert® Edge addresses these issues by enabling testing and treatment in a single visit.

Specifications and Features
The GeneXpert® Edge features a compact design with a "Load and Go" workflow, requiring minimal hands-on time. It uses a single-use, self-contained cartridge with integrated quality control, providing lab-quality test results. The system interfaces with laboratory information systems and includes data monitoring and management capabilities through Cepheid® C360.

Workflow
The testing process involves three simple steps with a total hands-on time of less than one minute: adding sample reagent to the sample tube, pipetting the sample into the cartridge, and inserting the cartridge to start the test.

Performance
The Xpert® MTB/RIF and Xpert® MTB/RIF Ultra tests detect Mycobacterium tuberculosis (MTB) and rifampin-resistance mutations in less than 2.5 hours. The tests offer excellent negative predictive value, simultaneous detection of MTB and rifampicin resistance, and high sensitivity even in smear-negative, culture-positive specimens.

Specifications
The GeneXpert® Edge has a 1-module configuration with dimensions of 9.4 cm width, 30.5 cm height, 29.7 cm depth, and a weight of 4 kg. It includes a touch screen tablet and an external battery pack.

Enhanced Tuberculosis Diagnosis
The Xpert® MTB/RIF Ultra provides results in less than 80 minutes and offers enhanced performance in HIV-positive patients and children. It reduces the need for culture confirmations due to its high negative predictive value and offers enhanced sensitivity over smear microscopy.
