Specimen Container

Sterile container
Virus swab

Specimen Requirement

Respiratory specimens are the best specimens. Nasopharyngeal aspirate is the specimen of choice (WHO). Other acceptable specimens include nasopharyngeal swabs, throat swabs, BAL and ETTA. At KKH, NP swab is preferred. Procedure for NP swab collection:
1. Use a Red cap virus swab tube.
2. Insert the flexible shafted swab into the nostril and back into the nasopharynx.
3. Leave swab for a few seconds to absorb secretions and withdraw with a rotating motion.
4. Sample the second nostril similarly.

Specimen Storage / Transport

• All specimens must be transported to the laboratory within 24 hours of collection, otherwise store at 40oC.
• Double-bag the specimen. Do not send by pneumatic tube.
• Please call the Molecular Microbiology Lab at 6394 1382 before sending the specimen to pre-empt the laboratory.
• Indicate on Virology Form: "NP swab (PCR) for H5N1" and write "ALERT: Suspect Avian Flu" on the form. Stamp ‘ISO’ on the form.
• Accompanying specimens for respiratory IF should be similarly stamped "ALERT: Suspect Avian Flu" and ‘ISO’ on the form.
