[VINASVI] INFLUENZA A SHELL V. + CULTURE
Nasopharyngeal wash+NP instructions:
1. Draw up 1-2 mL of sterile saline into a 3-5 mL syringe.
2. Remove the needle from the syringe and put on a butterfly
with a large tubing. Cut the tubing to a length of 2-3".
3. Place the tubing in the nasopharyngeal passage. Inject the
saline rapidly and draw back rapidly.
4. Inject saline and nasal material into the viral transport
medium. (If viral transport medium is not available, the NP
wash may be added to 1.O mL of trypticase soy broth or
sterile saline.)
5. After or before doing the wash, use a Dacron NP swab to do a
good epithelial cell scraping of the nasopharyngeal area.
Place and cut or break the swab into the same vial as the
wash. (Immunofluorescent testing is done on the epithelial
cells. The combination of both the wash and nasopharyngeal
scraping are essential to obtain enough cells to perform
the test.)
