What does PARR tell me about my patient’s specimen?

PARR, which stands for PCR for Antigen Receptor Rearrangements, is used to discriminate between lymphoma/leukemia and reactive/inflammatory conditions when cytology is equivocal. Our canine PARR assay detects the expansion of B-cell cancer clones by amplifying the VJ region of the immunoglobulin heavy chain gene (IgH) and detects the expansion of T-cell cancer clones by amplifying a region in the T-cell receptor gamma chain gene.

Can the blood sample be frozen or refrigerated before shipping?

The blood sample can be refrigerated before shipping. Please DO NOT freeze the blood sample.

Would we need to set up a Vet Portal for each doctor or just our hospital?

If you would like to set up accounts for the hospital, please send us a list of doctors' names and email addresses as well as any support staff who would need access to the Vet Portal. Each doctor can also register independently on the Vet Portal. Please note the report will be sent to the ordering veterinarian's email, not to all hospital accounts.

We have a case coming in today we would really like to submit but don’t have transport media tubes; is there any other method we could do in order to submit a sample, such as aspirating and placing it in tube with serum?

Please use serum and saline that you would normally do when you send to other reference laboratories.

I have a leukemia patient. Can you run an assay on blood?

Yes, we do run assays on blood for a leukemia patient. Please send us at least 2 mL of whole blood in an EDTA tube.

Is it wise to eliminate a certain chemotherapy drug based on the test results or should there be other factors that need to be considered in this decision?

We do not recommend using ImpriMed's predictions to rule out treatment options. The company's artificial intelligence is optimized to give high positive predictive value to help you find drugs with the highest likelihood of producing positive clinical outcomes. For the bests results, our predictions should be used in conjunction with expert knowledge from a skilled oncologist.
