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 test be used on cats and other animals?

At this time, we only offer commercial services to canine lymphoma patients. However, we are conducting research into feline lymphoma so if you would like to submit a sample please sign up here if you are interested in feline services.

How can I help to advance precision medicine?

The more samples ImpriMed processes and the more clinical outcomes we receive from our customers, the more accurately our AI models are able to determine which drugs will work best for your patients. (Click to read more)

What is a drug sensitivity test?

A drug sensitivity test is a lab test that measures how easily cells are killed by a drug.When you order a Personalized Prediction Profile, ImpriMed uses a proprietary high-throughput ex vivo drug sensitivity testing platform to analyze your patient’s live cells. For our canine leukemia and lymphoma service, we expose the cells to 13 different drugs commonly used to treat these diseases: L-Asparaginase, Mitoxantrone, Vincristine, Vinblastine, Doxorubicin, Rabacfosadine (Tanovea®), Chlorambucil, Mechlorethamine, Lomustine, Prednisolone (activated Prednisone), Mafosfamide (activated Cyclophosphamide), Melphalan, and Dexamethasone.-

What does flow cytometry tell me about my patient’s specimen?

ImpriMed’s flow cytometry report provides comprehensive information about the specimen’s immunophenotype. B-cell and T-cell immunophenotypes are useful in determining lymphoma/leukemia subtype and prognosis. In addition, our panel of ten antigens can also be used in the diagnosis of T-zonal lymphoma, acute leukemia, and other diseases. Antigens levels reported are: CD21, CD79a, CD3, CD4, CD8, CD5, CD45, CD34, CD14, and MHC class II. For more information, see: https://pubmed.ncbi.nlm.nih.gov/26953614/
