  • Once you’ve received the kit and materials you are ready to go; you can collect patient samples and ship them to ImpriMed via FedEx overnight. We are open 6-days a week to accept samples (Monday through Saturday).

What patient samples are required for ImpriMed services?

  • For canine lymphoma, please provide a fine need aspirate (FNA) sample and a blood sample for each patient.
  • For canine leukemia, only a blood sample is required.

How do I collect an FNA sample?

 ImpriMed steps for FNA collection – Please watch the video here or read on

  1. Disinfect the skin with alcohol (70%) at the planned needle puncture site.
  2. Insert a 20-gauge needle (without syringe) into an enlarged lymph node and perform 15 - 20 aspirations using an aggressive “woodpecker style” technique. Stop aspirating when the aspirate appears in the hub of the needle.
  3. Attach the needle to a 5 - 10 mL syringe (with at least 1 ml of air). Tilt the collection tube upside down and inject the aspirated material directly into the medium.
  4. Allow a small amount of fluid (~1/4 mL) to flush back into the needle, then gently reinject into a fluid medium to flush out the needle.
  5. Repeat the procedure multiple times to ensure all the aspirate is transferred into the media tube. We need at least 10 million cells to conduct the drug response predictions, so if you need to aspirate from other affected nodes please do so. There are no additional costs for additional nodes or tubes. Typically, 2 FNA tubes of adequate cellularity are required to reach 10 million cells. If a blood vessel was lacerated during the procedure and the collection tube becomes significantly bloody, please select a different biopsy site and repeat the procedure. Store any FNA tubes in the fridge immediately after the biopsy. DO NOT freeze samples or the transport media.
  • We also accept fresh lymph node tissue and spleen samples (within 24 hours of collection).

How many cells are needed for each type of service?

The cell counts required for each assay are below:

  • Personalized Prediction Profile or Drug Response Predictions: 10 million
  • Immunoprofile: 1 million
  • Flow cytometry: 700,000
  • PARR: 300,000

What does flow cytometry tell me about my patient’s specimen?²

  • 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:

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.³

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.
  • If you believe the ImpriMed Personalized Prediction Profile may help you to identify the most effective treatments for a patient, be sure to notify the pet parents that this service is an option for them.
  • One of the huge benefits of AI-led diagnostics like ImpriMed is the ability to be constantly developing and improving based on the feedback of existing cases. This prospective approach to the evolution of the assay improves the accuracy and therefore the applicability for all patients. Because of this philosophy to constantly improve the service; we try to reach out to our clients a few months after a test is run to gather basic data on how the test performed. We have developed a simple standardized form to make this as easy as possible and we appreciate your support in advance. If you have any concerns over the test, this ensures we can address them to help improve the service you are able to offer your clients.
