Working Principle of Genexpert
The Genexpert system is a laboratory-based, rapid molecular diagnostic test for the detection of tuberculosis (TB) and other infectious diseases. It is considered an expert test in the field of diagnostics.
The principle behind Genexpert is the use of nucleic acid amplification technology, specifically the polymerase chain reaction (PCR). This allows for highly sensitive and specific detection of nucleic acids from the target organism.
Sample Processing
The Genexpert test starts with the processing of the patient sample, which can be sputum, urine, or other clinical specimens. The sample is treated with a lysis reagent, which releases the genetic material from the cells. This step is crucial for subsequent amplification and detection.
Amplification and Detection
The released genetic material is then mixed with reagents that contain primers targeting specific regions of the target organism’s genome. These primers provide a template for the amplification of the target DNA or RNA sequences.
The Genexpert system uses a rapid cycling PCR technique, which allows for fast and efficient amplification of the target sequences. This is achieved through a combination of temperature cycling and the use of a special enzyme called DNA polymerase.
During each temperature cycle, the DNA strands separate and the primers bind to their complementary sequences. The DNA polymerase then adds new nucleotides to the growing DNA chain, resulting in the exponential amplification of the target sequences.
In addition to amplification, the Genexpert system also includes a step for real-time detection of the amplified product. This is achieved by incorporating fluorescent probes into the reaction mixture. As the target sequences are amplified, the probes bind to the amplified products and emit fluorescence, which can be detected by the machine.
The Genexpert system automatically interprets the fluorescence signals and generates a result within a few hours. This rapid turnaround time makes it an invaluable tool for the diagnosis of infectious diseases, particularly tuberculosis.
