  • Wuhan strain will continue to arise, yet not all viral variants generated through mutation of the virus are important or have immediate public health relevance. (who.int)
  • Viral supression allows for immunologic improvement (as measured by CD4 counts), prevents the selection of drug-resistance mutation, and decreases HIV transmission to others. (medscape.com)
  • The FluoroType ® SARS-CoV-2 varID Q also provides a viral load result according to WHO standard (IU/ml), as well as CP values and easy interpretation of mutations. (bruker.com)
  • A QoI-LAMP assay was also developed to detect the G143A mutation in cytochrome b associated with QoI-resistance in C. beticola. (usda.gov)
  • Current applications include replacing tissue testing when that is difficult or fails, re-testing as disease progresses on treatment, and earlier detection of drug resistance. (nature.com)
  • Several techniques are currently available to detect cfDNA, including highly sensitive PCR (polymerase chain reaction) assays and next-generation sequencing (NGS). (nature.com)
