Submission and Collection Notes
Complete all fields of the requisition form.
Confirm that the correct information is listed on the requisition as per the Acceptance/Rejection Criteria section above.
For serology, PHO prefers centrifuged SST for serological testing. Generally, only one full 5 mL SST is sufficient for testing a combination of up to six infectious disease serology markers. If a full tube cannot be drawn and more than six markers are requested, submit two tubes. Refer to Serology Testing – Laboratory Specimen Collection and Submission Instructions for more information.
Label the specimen container(s) with the patient’s first and last name, date of collection, and one other unique identifier such as the patient’s date of birth or Health Card Number. For additional information see: Criteria for Acceptance of Patient Specimens. Failure to provide this information may result in test cancellation or testing delay.
CSF antibodies may be detectable in patients with encephalitis, and ocular fluid antibodies may be detectable in patients with ocular infection, but these are not validated specimen types for antibody testing and require approval. If needed, contact PHO’s customer service for information.
