Advantages of seva tb elisa

  •  The test can be done in simple hospital setting

  •  Helpful in childhood tuberculosis where sputum sample is difficult to obtain

  • Helpful in clinically suspected tuberculosis cases negative by routine diagnostic methods  like AFB  ear & culture examination.

  •  Useful in confirming tubercular aetiology in extrapulmonary tuberculosis viz; tubercular        lymphadenopathy, meninges-CNS tuberculosis, genito-urinary tuberculosis, bone & joint        tuberculosis, abdominal tuberculosis etc.

  •  Useful in immunomonitoring for confirming elimination of infection and patient’s       compliance in  tuberculosis cases during antituberculosis therapy

  • Preferred over the insensitive, cumbersome or time consuming & widely unavailable, invasive &  expensive tests such as Bacteriological, Radiological, FNAC, Laproscopic    biopsy, USG, CT,    Radionucleide bone scan, DNA probes, PCR etc.
