Submission and Collection Notes
If you suspect a case of Smallpox or non Molluscum Cotagiosum/Poxvirus - Consult immediately with the Medical Microbiologist at Public Health Ontario Laboratory and your local Public Health Unit.
Sample can be collected as a dry swab or added to a minimum volume of viral transport media, avoid excessive dilution of the sample.
Sample submitted on a glass slide is not suitable for testing.
Storage and Transport
Label the specimen with the patient’s full name, date of collection and one other unique identifier such as the patient’s date of birth or Health Card Number.
Place the specimen container in the biohazard bag and seal the bag; insert the completed requisition in the pocket on the outside of the sealed biohazard bag. To maintain optimal viability of the virus, specimens should be stored at 2-8°C following collection and transported to PHO on ice packs within 72 hours of collection. If longer storage/transit time is anticipated, specimens should be frozen at -70°C or lower and transported on dry ice. Fresh Biopsies should be transported on dry ice.
Special Instructions
Complete all fields of the PHO General Test Requisition Form: include the requesting healthcare provider's CPSO#, complete mailing address, telephone, and fax number, and the patient’s full name, date of birth, Health Card Number (must match the specimen label). Failure to do so may result in rejection or testing delay.
Test Frequency and Turnaround Time (TAT)
Turnaround time is approximately 14 days from receipt at NML.
