Is the VDI-TK test reliable for testing feline intestinal lymphoma? Is there a high likelihood of false-positive or false negative result from the test? Thank you for answering the question. Pet's info: Cat | Siamese | Male | neutered | 8 lbs

Dr. Strydom, DVM · Accepted Answer

The VDI-TK test has a sensitivity of 0.78 and a specificity of 0.91 (High Positive Specificity >0.98) A highly sensitive test means that there are few false negative results, and thus fewer cases of disease are missed. The specificity of a test is its ability to designate an individual who does not have a disease as negative. A highly specific test means that there are few false positive results. Based on that, I would say that it is a reliable testing method for feline lymphoma.
