Sera analyzed for the detection of antibodies to F. tularensis.
Human serum sample. Minimum volume required – 1.0 mL. Hyperlipemic, hemolysed or contaminated sera may yield erroneous results.

Appropriate clinical symptoms and suspected exposure to animals infected with F. tularensis.
Please list all clinical symptoms appropriate to the suspected area of infection detailed by submission of a completed Bioforensics Assay Development and Diagnostics requisition form and clearly specify organism testing request on the requisition form. Append all relevant clinical background information and testing performed.
Specimens may be subject to rejection if they are not the appropriate sample type, have insufficient volume, or are not accompanied by relevant patient information.
THIS TEST IS PERFORMED FOR INVESTIGATIONAL OR RESEARCH PURPOSES ONLY
In-house microagglutination test (MAT). This is a semi-quantitative test for the detection to F. tularensis, where a single serum titre of ≥128 is considered positive. A four-fold or greater increase in titre between two serum samples drawn a minimum of 4 weeks apart is considered presumptive evidence of a recent or current infection with F. tularensis.
30 calendar days. Please note that during times when large numbers of samples are received or if tests must be repeated the turnaround time may be longer.
