Occult Heartworm - OH

Sample Details: 1 mL serum or 1 mL EDTA or heparin plasma
Cost/Fee: $17.00
This test is validated for use in domestic or wild dogs and cats only. Other animals may be tested by this method, but reactivity in other species is not clearly defined. This test method can be used to detect Dirofilaria immitis five to six months after infection in dogs, and seven to eight months after infection in cats. Because of the nature of this disease in cats, veterinarians may want to consider including feline heartworm antibody testing for a more accurate assessment of a cat’s true infection status. If a Knott's heartworm test (microfilarial detection) is also desired, EDTA or heparin whole blood (1.0 mL) is needed. Please clearly indicate each test as unique test requests.
