Discuss what are the various approaches to case finding that are employed under NTEP to diagnose a case of TB at the earliest.

The operational definitions specify the criteria that are required to identify individuals from populations that may be vulnerable to TB or highly likely to be a case of TB.

Screening and Diagnostic technologies are tests that objectively identify cases under various definitions.

They are used at specific time points for one or more indications, such as identification and diagnosis of TB infection, presumptive TB, TB disease, routine followup and diagnosis of drug resistance, as per the various diagnostic algorithms.

They are classified based on the technology as Microscopy, Phenotypic, genotypic, Radiological and Histopathological tests. Other tests may be used for identifying TB infection such as Mantoux and IGRA.
