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.

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/

How long does the media last before expiring? How long is the medium good for?

The media has a 3 month shelf life. You can check the tube and look for its expiration date as well.

Do you test "rescue" drugs as well?

Yes, many of the 13 anticancer drugs we provide predictions for are used for rescue therapy. The drugs we test against are: L-Asparaginase, Mitoxantrone, Vincristine, Vinblastine, Doxorubicin, Tanovea, Chlorambucil, Mechlorethamine, Lomustine, Prednisone, Cyclophosphamide, Melphalan, and Dexamethasone.

What is included in the ImpriMed Immunoprofile service?

The ImpriMed Immunoprofile service includes both our Flow Cytometry and PARR reports. These comprehensive results can be used to detect the presence of lymphoma or leukemia and determine the disease subtype.

Can the blood sample be frozen or refrigerated before shipping?
