    Remark

  • Only a positive result is conclusive.
  • Reasons for negative results:
      • - It is not a urothelial (transitional cell) carcinoma.
      - The carcinoma does not have copy number alterations/BRAF mutation.
      - There were no or not enough relevant cells present in the sample.
      - There is severe (secondary) inflammation.
  • Testing for CNAs is not suitable for prostate cancer.
  • The test cannot be used for cats.
