Antech Diagnostics has determined that EDTA plasma (LTT) can falsely increase cortisol concentrations by as much as 30%. Serum is the specimen of choice for cortisol testing. LTTs are not acceptable samples for cortisol testing.

An increased volume of rabies testing is resulting in longer turnaround times from the Rabies Diagnostic Laboratory at Kansas State University.

FAVN (Fluorescent Antibody Virus Neutralization)
This test is required for pets being exported to Hawaii and many other countries, including all of Europe. This test can take 4-6 weeks for completion of the assay and processing of paperwork. Test Code S17108.

RFFIT (Rapid Fluorescent Focus Inhibition Test)
This test is required by Australia, New Zealand, and some other countries. This test also is used to assess rabies virus vaccine titers, in special circumstances. It can take 2-4 weeks to complete the testing. Test Code S16685.

Samples submitted for rabies testing for export purposes must be accompanied by a completed FAVN or RFFIT form, which are available from Antech Diagnostics. The pet's microchip ID number must be written on the FAVN or RFFIT form. Please contact Client Services if you require these forms or have questions regarding rabies testing.

For blood lead measurement, the test requires a LTT that must be at least ½ full.
