AFB-MTb antibiogram Pyrazinamide

The AFB-MTb antibiogram Pyrazinamide is a targeted laboratory service that determines Mycobacterium tuberculosis (MTB) susceptibility to the anti-tubercular agent pyrazinamide. The test typically uses a culture isolate or sputum sample to perform phenotypic susceptibility testing and, where available, reports minimum inhibitory concentration (MIC) or categorical results (Sensitive / Resistant). Accurate pyrazinamide susceptibility results are essential for designing effective TB regimens and avoiding inadequate therapy that can promote resistance.

This home-collection service brings specimen pickup and transport to accredited Dubai and UAE laboratories, providing convenience for patients and faster clinical decision-making. It is most useful when MTB has been detected or cultured and clinicians need definitive pyrazinamide susceptibility to tailor initial or modified treatment plans, manage suspected treatment failure, or evaluate contacts of drug-resistant TB cases.

• AFB smear / culture for Mycobacteria
• Mycobacterium tuberculosis identification
• Pyrazinamide drug-susceptibility (Sensitive / Resistant)
• Pyrazinamide MIC (where applicable)

• Confirmed or suspected MTB infection requiring drug-susceptibility
• Poor clinical response or treatment failure on standard TB therapy
• Known exposure to multidrug-resistant TB (MDR-TB) contacts
• Before initiating or modifying anti-TB regimens that include pyrazinamide
• Confirmation of resistance patterns from a previously positive culture

• Home sample collection across Dubai and the UAE for patient convenience
• Accurate, laboratory-based pyrazinamide susceptibility results
• Enables tailored anti-TB treatment and reduces risk of ineffective therapy
• Rapid reporting to the treating physician to support timely clinical decisions
• Testing performed in accredited laboratories following UAE clinical standards

• Early-morning sputum sample collection at home (preferred) or laboratory-provided culture isolate
• Multiple samples may be requested depending on initial smear/culture status
• Provide current anti-TB medication history and clinical details at time of collection
• Ensure specimen is available for same-day pickup and transfer to the testing laboratory
