SUMMARY

The MDR/XDR-TB Colour Test is a simple, safe, low-cost, appropriate-technology test for diagnosing TB and concurrently determining antibiotic-susceptibility testing. This test helps ensure that patients in resource-constrained settings receive the best treatment for their TB disease.   The MDR/XDR-TB Colour Test was invented and developed by the IFHAD research group in Peru and has since been evaluated in multiple countries – please see the publications below.
