An AFB-DNA (TB-PCR) Detection by Real-Time PCR with Reflex to Rifampicin Resistance by Ultra CBNAAT on Body Fluids is a specialized, rapid molecular diagnostic profile. It is specifically designed to diagnose Extrapulmonary Tuberculosis (EPTB)—tuberculosis that has developed outside of the lungs in various fluid-filled compartments of the body.

Because tuberculosis bacteria are notoriously difficult to find under a microscope in liquid body samples (paucibacillary samples), this DNA-amplification test provides an essential, highly sensitive diagnostic solution.

What Types of Body Fluids Are Tested?
This panel can be performed on several types of clinically harvested fluids, depending on where the infection is suspected:

Cerebrospinal Fluid (CSF): Taken via a lumbar puncture to diagnose life-threatening TB Meningitis (infection of the membranes surrounding the brain and spinal cord).

Pleural Fluid: Drawn from the space surrounding the lungs to diagnose TB Pleurisy.

Ascitic / Peritoneal Fluid: Collected from the abdominal cavity to diagnose Peritoneal TB (gastrointestinal tuberculosis).

Synovial Fluid: Extracted from a swollen joint space to evaluate TB Arthritis or musculoskeletal tuberculosis.

Pericardial Fluid: Harvested from the sac surrounding the heart to diagnose TB Pericarditis.
