OncoK9™ Information for Veterinarians

Below is a selection of common questions and answers. To view the complete OncoK9 knowledgebase, please visit our Veterinary Support website.

A Cancer Signal Detected result indicates that cancer-associated genomic alterations were detected in the sample. This significantly increases the likelihood that cancer is present but does not confirm the presence of cancer. This result should not be used as the sole basis for making important decisions such as treatment of euthanasia. A full clinical evaluation must be performed to establish a definitive diagnosis.

Each case is different, and followup diagnostic workup is at the discretion of the veterinarian. A cancer-focused clinical evaluation is advised, with a thorough physical exam (including oral and rectal exam), thoracic and abdominal imaging, and sampling of any masses or enlarged lymph nodes found on exam or workup. Advanced imaging such as CT, MRI, or PET may also be indicated in specific cases.

If the clinical evaluation does not result in a cancer diagnosis, this could mean that the selected confirmatory tests did not identify the cancer, or that the test result was a false positive. Advanced or confirmatory diagnostics, such as ultrasound, CT, or tissue sampling of any masses or enlarged lymph nodes, if not already performed, are advised. Further evaluation and/or monitoring of this patient should be considered. A retest with OncoK9 may be offered; we encourage clinicians in this situation to contact our team for support and to discuss eligibility.

OncoK9 is a multi-cancer early detection test meaning it detects multiple classes of genomic alterations associated with a wide variety of cancers. You can view a list here of cancer types that OncoK9 has been shown to detect, in the validation study.

No. OncoK9 is indicated for use in domestic canids only (pet dogs). Dogs and cats have unique genomes. OncoK9 has been uniquely designed to only work in dogs. In the future, we hope to be able to extend this technology to cats.

It is not necessary to do anything special to prepare the sample for shipment in relation to climate temperatures. Simply folow the standard procedures and use the shipping supplies provided in the OncoK9 test kit. Please keep the sample indoors until it is handed off to FedEx®. Do not set it out for the courier to pick up.

It is winter and the temperature is below 65°F/18°C.
It is summer and the temperature is above 77°F/25°C.

Sedatives and/or anesthetics are not expected to impact the OncoK9 test. If the pet is scheduled to have surgery and samples are to be collected in the peri-operative time period, note that it is acceptable to collect samples are collected after the pet is intubated and anesthetized; however please ensure that the samples are collected before any surgical incision has been made, as this may release large amounts of cell-free DNA into circulation, which could impair the test’s performance.

Yes, we can send a replacement. Please do not use any expired components. Please reach out to your PetDx Customer Success Manager, or contact a member of our support team at: , or call 833-464-7297. You can also visit our Support Portal and submit a ticket with the details at: support.petdx.com. We will send you replacement kits and determine if the kits you have on hand need to be shipped back to us.

The test is looking for cell-free DNA fragments that are present at very low concentrations in plasma. OncoK9 requires a 14-17mL blood volume in order to obtain sufficient cell-free DNA from a sample to meet our stringent quality control requirements.

OncoK9 looks for cancer-associated genomic alterations in a sample. If these are found, a Cancer Signal Detected report is issued. Samples in which no cancer-associated genomic alterations are identified are reported as Cancer Signal Not Detected. The test does not provide a definitive cancer diagnosis, and it should never be used as the sole basis for making important decisions such as treatment or euthanasia. A full clinical evaluation should be performed to establish a definitive diagnosis. Similarly, this test does not provide information about a patient’s genetic risk for developing cancer or other clinical conditions in the future. The results only indicate the detection or non-detection of cancer signal in the patient’s blood at the present time.

Cancer signal prediction has been validated for lymphoma, and research is ongoing to add cancer signal prediction for more cancer types. Results obtained when testing cancers other than lymphoma with OncoK9 are presently limited to reporting the presence or absence of cancer-associated genomic alterations — a “cancer signal”. A veterinarian can use the provided information to guide their next steps.
