Requisitions and Kit Ordering

Test Frequency and Turnaround Time (TAT)

The adenovirus testing by electron microscopy (EM) is performed daily Monday to Friday. 

Turnaround time for EM is up to 3 days from receipt by PHO laboratory.

Samples tested by virus culture are observed for a minimum of 10 days prior to reporting a negative culture result; samples that are positive can be observed at any point during this period.

Turnaround time for virus culture is up to 12 days from receipt by PHO laboratory.

TAT will vary during the winter months.

Test Methods

Adenovirus specimens are tested by electron microscopy and traditional virus culture. (Most viruses responsible for gastroenteritis in the winter do not grow in cell culture. Therefore, virus culture is only performed from April 15th to December 14th). Electron microscopy is done year round.
