Simplificar os testes de suscetibilidade a fármacos para a TB utilizando uma maior capacidade de multiplexagem com a tecnologia GeneXpert® de 10 cores

A necessidade

In 2022, only 43% of the total estimated multidrug-resistant Tuberculosis (MDR-TB) incident cases were diagnosed and enrolled on treatment regimen¹
Only 47% of the total notified MDR-TB cases were tested for resistance to fluoroquinolones¹
Increase access to rapid and extended drug resistance profiling for all TB-positive cases to rule out MDR/pre-XDR^{^} TB2

A solução

A male and a female researchers scanning cepheid test cartridges.

The Xpert MTB/XDR test enables rapid molecular DST. When combined with the frontline Xpert MTB/RIF Ultra test, it detects mutations associated with resistance to isoniazid (INH), fluoroquinolones (FLQ), second-line injectable drugs (SLIDs), and ethionamide (ETH) in a single test.

Fast time to result for molecular DST
Resultados em menos de 90 minutos
Same easy-to-use process as the Xpert MTB/RIF Ultra test
Execução nas plataformas GeneXpert® existentes equipadas com módulos de 10 cores

O impacto

A smiling female doctor attends an elderly woman.

Upfront molecular DST for TB‑positive cases supports timely treatment planning
Helps supports expanded access to drug‑resistance testing for MDR and pre‑XDR TB.³
The Xpert MTB/XDR assay provides the capability to differentiate between high and low-level resistance to INH and FLQ, which which provides additional information that may support resistance interpretation alongside clinical findings.⁴
