Molecular virology is the study of viruses at the level of nucleic acids and proteins. A number of methodologies are currently available in LabQuest for viral diagnosis and basic research, ranging from immunological methods, such as ELISA, to molecular methods, such as PCR-based diagnosis. The Applied Biosystems QuantStudio™ 5 RT-PCR is utilized by Lab Quest, which enables improved data accuracy and sensitivity for a broad range of genomic applications such as COVID-19 testing, HBV DNA, HCV RNA, and HLA-B27 DNA, HPV DNA screening, and so on.
