Dry Swab RT-PCR Method for Covid Detection Approved By ICMR

Dry swab-direct RT-PCR, developed by CSIR’s constituent lab Centre for Cellular and Molecular Biology (CCMB), Hyderabad, for scaling up coronavirus detection, has now been approved by the Indian Council of Medical Research.

This method developed by CSIR-CCMB is a simple variation of the existing gold standard RT-PCR method and can easily scale up the testing by two to three-fold with no new investment of resources.

CSIR-CCMB has been testing samples for coronavirus since April 2020. Working closely with the healthcare workersTelangana's identified some of the key issues that slow the testing process. In response to it, the researchers here developed the dry swab RNA-extraction free testing method for Covid-19.

More specifically, the dry swab-direct RT-PCR method involves collecting and transporting the nasal swab in a dry state (instead of using the viral transport medium VTM), which makes the transportation and handling of the samples easy and less prone to spillage and spread of infection.

Significantly, the modified method of CSIR-CCMB has also been independently corroborated by multiple premier institutes and hospitals such as the Centre for DNA Fingerprinting and Diagnostics (CDFD), IISER-Berhampur, CSIR-Neeri, GMCH-Nagpur, Genepath based in Pune, IGGMSH and MAFSU, Nagpur and also Apollo Hospitals, Hyderabad.
