A thorough history and physical examination are vital to detect many of the conditions associated with a feline leukemia virus infection. A diagnosis of feline leukemia can be confirmed by several different kinds of tests. However, a quick blood test called an ELISA, performed by the veterinarian, can detect the presence of the virus.
Cats that test positive for feline leukemia should have baseline blood work done to see if the virus is causing diseases of the organ systems. A chemistry panel will help detect diseases of organs such as the kidney and liver. Also, a complete blood count, or CBC, will determine the number of red blood cells, white blood cells and platelets. The virus can reduce significantly the bone marrow's production of these vital cells.
X-rays of the chest and abdomen often are taken to detect the presence of cancer.
