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.

I have a patient with likely lymphoma/leukemia. For a blood sample, can I just submit an EDTA blood tube or do I still use the ImpriMed tubes (and if so, how many tubes and is an additional EDTA blood tube still needed with that)?

If the patient is suspected of leukemia, blood collected in the EDTA tube should be fine. If it is lymphoma, we might need FNA from the affected organ/lymph node. We can suggest FNA in ImpriMed media tube (1) and 2ml of blood sample in an EDTA tube.

How do vets report back the outcomes to feed back into the AI model? Is this something that can be easily done via the Vet portal?

We usually send you an email asking for patient records about 3-6 months after you receive the final ImpriMed report. Once we receive the record, we input the data into the AI Models, it is not yet something that can be submitted on the Vet Portal.

Yes, probably the patient would be taking some form of drug treatment when we look at the progression-free survival graph. Basically, the patients were not treatment free at the time.
