Single Nucleotide Polymorphisms (SNPs)<<Return to Laboratory
Accredited by the Standards Council of Canada to Laboratory no. 594 - CAN-P-4E (ISO/IEC 17025).
Molecular typing of Yersinia pestis strains to determine genetic variations between members of a species.
Pure bacterial culture.
Pure bacterial culture – plate or swab.
Store bacterial cultures refrigerated until shipped for testing
Shipping of specimens shall be done by a TDG certified individual in accordance with TDG regulations. For additional information regarding classification of specimens for the purposes of shipping, consult either Part 2 Appendix 3 of the TDG Regulations or section 3.6.2 of the IATA Dangerous Goods Regulations as applicable.

Confirmed Yersinia pestis infection.
Completed Bioforensics Assay Development and Diagnostics requisition including sender name, address and telephone number. Patient name or identifier (referring lab #), date of birth, suspected exposure, test(s) requested, clinical history. Type of specimen and date collected. If possible, include the antibiotics administered and travel history.
The SNP pattern will be determined through PCR, looking for single base pair mutations at a specific locus which usually consists of two alleles.
14 calendar days for a final result.
