On completion of a test run, the Cartridge-based Nucleic Acid Amplification Test (CBNAAT) gives the following results:

  1. MTB DETECTED; Rif Resistance DETECTED
  2. MTB DETECTED; Rif Resistance NOT DETECTED
  3. MTB DETECTED; Rif Resistance INDETERMINATE
  4. MTB NOT DETECTED
  5. Error
  6. Invalid
  7. No result

Conclusive results include: MTB NOT DETECTED, MTB DETECTED with Rif Resistance/ without Rif Resistance.

Non-conclusive results include: MTB Detected, Rif Resistance Indeterminate, Errors, Invalid and No Result - the test has to be repeated in these cases.
