Expand your lab’s potential
for drug-resistant tuberculosis testing

The European Tuberculosis Laboratory Initiative recommends molecular testing and early identification of MDR as standard for TB diagnostics1

  • Determination of antibiotic resistance is critical in managing the treatment pathway and potential isolation processes for confirmed TB positive patients
  • Testing only for RIF resistance can lead to improper treatment of patients with RIF-susceptible/INH-resistant TB resulting in high failure rates, relapse and development of MDR-TB2
  • Fast diagnosis can accelerate patient treatment and prevent disease transmission
  • BD MAX™ MDR-TB is a real-time PCR assay with a high level of sensitivity, detecting Mycobacterium tuberculosis complex (MTBC) as well as key mutations associated with RIF and INH resistance

Treatment success rates for TB and drug-resistant TB are still below regional and global targets3

BD MAX™ MDR-TB: an integrated molecular solution that delivers 4 clinical results in one test4

  • MTBC
  • Mutations in the rpoB gene associated with rifampicin resistance
  • Mutations in the katG gene and inhA promoter region associated with isoniazid resistance
  • Can be used with fresh and processed sputum samples, BD Sample Treatment Reagent designed to minimise bioburden for effective sample processing
  • Same day results possible with a turnaround time of less than 4 hours for 24 samples

The BD MAX™ MDR-TB assay has high sensitivity and specificity for detection of MTB and RIF and INH drug resistance and may be an important tool for rapid detection of TB and MDR-TB globally5

  • The high sensitivity of BD MAX™ MDR-TB for TB detection and multi-drug resistance adds predictive value to the TB diagnostic process and clinical decision making
  • Specific assay results for katG and inhA promoter, the two most well-known gene mutations which cause isoniazid resistant TB further direct appropriate medication dosages and combinations for successful patient treatment planning

Clinical performance in several high-burden settings demonstrated4

Detection Sensitivity (95% CI) Specificity (95% CI)
MTBC* 93% 99%
RIF resistance 94% 98%
INH resistance 82% 100%
*fresh sputum sample

BD has a legacy of trust and leadership in efficient and accurate diagnostics including sample collection, TB detection and drug susceptibility and resistance testing.
