Requisition Forms
Reference Details
Susceptibility testing to Amantidine for Influenza A virus.
- Influenza
Viral isolate, minimum volume 0.5 mL required, if no additional testing requested.
N/A
Keep samples refrigerated until shipped for testing. Ship on dry ice.
Shipping of specimens shall be done by a TDG certified individual in accordance with TDG regulations. For additional information regarding classification of specimens for the purposes of shipping, consult either Part 2 Appendix 3 of the TDG Regulations or section 3.6.2 of the IATA Dangerous Goods Regulations as applicable.
Suspected or confirmed influenza infection.
Completed requisition (current Drug Susceptibility Testing for Influenza Virus requisition form). The sender's lab name, address, and telephone number must be included for samples to be processed. Also include identifier (sender lab number), patient date of birth, patient gender, type of specimen, and date collected. Under additional information, please include if possible/applicable: passage history, patient travel history, extent of influenza activity, and date of collection relative to antiviral use.
N/A
Influenza isolate susceptibility to antivirals is determined by sequence analysis. For sequence analysis, specific regions of the viral genome are amplified by PCR and sequenced; comparison of the sequence data with known wild-type sequences reveals the presence of any mutations known to cause resistance to the antiviral.
