Genexpert PCR for Tuberculosis (TB)

KSh5,625

#### Test Description
The Genexpert PCR (polymerase chain reaction) for Tuberculosis (TB), also known as the Xpert MTB/RIF assay, is a rapid molecular diagnostic test used to detect Mycobacterium tuberculosis complex (MTBC) and resistance to rifampin (RIF) in both pulmonary and extrapulmonary specimens. The assay performs sample processing and PCR analysis in a single hands-free step, allowing for the rapid diagnosis of TB disease and drug resistance[2][3].

#### Indications of the Test
The test is indicated for individuals suspected of having TB, especially those at risk of multidrug-resistant TB (MDR TB), as it can quickly identify possible MDR TB by detecting RIF resistance, which is a predictor of MDR TB[2][4].

#### Patient Preparation/Instructions
No special patient preparation is required for the Genexpert PCR test. The test typically involves the collection of sputum or other relevant specimens for analysis.

#### Typical Reference Values
The typical reference values for the Genexpert PCR test are the presence or absence of MTBC and RIF resistance in the patient’s specimen.

#### Turnaround Time
The assay can generally be completed in less than 2 hours, providing rapid results for the detection of TB and drug resistance[3][4].
