Introduction

Cartridge-based Nucleic Acid Amplification Test (CBNAAT) is an automated rapid molecular diagnostic test which detects targeted Deoxyribonucleic Acids (DNA) sequences of Mycobacterium tuberculosis (M.tb) genome by Real-time Polymerase Chain Reaction (RT-PCR) method.

The consumables required at a Cartridge-based Nucleic Acid Amplification Testing (CBNAAT) laboratory include the following:

CBNAAT/ GeneXpert Dx System consisting of CBNAAT machine preloaded with assay software, Computer and the Barcode reader

The National TB Elimination Programme (NTEP) laboratory network is composed of National Reference Laboratories (NRLs) at the national level, at the state level Intermediate Reference Laboratories (IRLs) and Culture & Drug Susceptibility Testing (C&DST) laboratories and at the peripheral level Designated Microscopy Centres (DMCs).

Each of these laboratories is responsible for performing various functions at its own levels.

Ni-kshay Aushadhi is a web-based portal that deals with the management of stocks (anti-TB drugs, consumables and other commodities) across all the stocking points across the National TB Elimination Programme (NTEP), i.e., Government Medical Store Depot (GMSD), Central Medical Services Society (CMSS) warehouses, State Drug Stores (SDS), District Drug Stores (DDS), TB Units (TUs) including Peripheral Health Institutes (PHIs).

• Good quality sputum collection is of paramount importance in tuberculosis diagnosis.
• Once a person is identified as presumptive TB, s/he is referred to the Designated Microscopy Centre (DMC) for sputum collection.
• For TB diagnosis two sputum samples are collected - one is the supervised ‘spot’ sample collected at the DMC (labelled Specimen A) and the other is the early morning sample collected by patient themselves at his/her home (labelled Specimen B).

Sputum smear microscopy is an integral part of the National TB Elimination Programme's (NTEP’s) diagnostic services and can majorly impact the success of the programme.

It is essential to have a credible and well-established quality assurance system to assess the performance of the microscopy service.

NTEP has implemented a multi-level quality assurance network system of sputum smear microscopy in the country consisting of: 

1. Internal Quality Control (IQC)
2. External Quality Assessment (EQA)
3. Quality Improvement (QI)

• Designated Microscopy Centres (DMCs) are the most peripheral laboratory under the National TB Elimination Programme (NTEP) network. Therefore, it is very important for the DMCs to maintain an adequate stock of all consumables.
• A paper-based stock register is maintained at the DMC and submitted as a part of the ‘Monthly report on programme management, logistics and microscopy’.
