Question 1

What is the DeepScan CFD® biomarker and how does it work?

Accepted Answer

The DeepScan CFD® biomarker measures circulating cell-free DNA (cfDNA) levels in blood released from damaged or dying cells, and it reveals elevated levels that correlate directly with cell destruction in the body. This provides veterinarians with critical insights into disease severity, hidden conditions, and treatment effectiveness.

Question 2

How does the CFD® biomarker differ from regular blood tests?

Accepted Answer

Traditional blood tests measure cell function and organ chemistry but often don't detect early-stage disease. CFD® focuses on cfDNA released when cells die or are damaged, surfacing cell destruction earlier in many cases.

Question 3

Which dog breeds benefit most from CFD® biomarker?

Accepted Answer

All dogs over 6 years old benefit from CFD® biomarker, but especially cancer-prone breeds like Labrador Retrievers, German Shepherds, Golden Retrievers, Boxers, and Bernese Mountain Dogs.

Question 4

How reliable is the CFD® biomarker?

Accepted Answer

CFD® is a quantitative biomarker validated on over 5,000 samples. Each score is compared against a personalised reference range accounting for breed, age, sex, and neutering status. In clinical studies, the majority of dogs with confirmed cancer had CFD® scores outside the reference range. Results are interpreted in clinical context rather than as a yes/no answer.

Question 5

Is the CFD® biomarker non-invasive?

Accepted Answer

Yes. CFD® biomarker is completely non-invasive and painless. It works by taking a simple blood sample taken from the dog's front or back leg—the same routine draw as other blood work, without tissue biopsies or imaging.

Question 6

How often should CFD® be measured?

Accepted Answer

The recommended frequency is annually during health checkups. For high-risk breeds or follow-up monitoring, your veterinarian may suggest more frequent sampling, such as every 6 months.

Question 7

How long does sample processing take?

Accepted Answer

Sample processing in the laboratory takes 3-5 business days. Results are sent by email and are also available in the web service.

Question 8

What should be done after high-risk results?

Accepted Answer

For high-risk cases, follow-up investigations are recommended: imaging (ultrasound, X-ray), additional blood tests, and possibly biopsy. Results should always be interpreted in the context of the clinical picture.
