I want to know the procedure followed in labs after receiving the specimen in VTM. Should we centrifuge the VTM & directly use the VTM for testing or any other media is added to VTM & the processed further for testing?
If specimen received in VTM then no need to add any other medium. But if you collected nasal swab then you need to add VTM. Rest protocol is simple...spin (10-12K 10 min)....take out everything in collection vial and do the lab testing. Basically make sure you are giving sufficient time to elute everything from swab or applicator. You can find detail protocol in WHO reference publications...
Contact to Dr Shailesh pawar, Scientist NIV Pune, he is regularly testing via hemagglutination assay, propagation of virus in MDCK cell, RT-PCR method etc...
