While microfilarial testing is not a primary diagnostic tool for heartworms, it does help to get a better overall picture of what is being dealt with. Heartworm preventatives take care of heartworms at immature stages, so in a patient with preventatives, microfilaria may not be present.
On the other hand, sometimes a heartworm test may not be conclusive. In these instances, an adjunct microfilaria screening can help with a confirmation, as the presence of microfilaria shows positive presence of adult heartworms.
Given the relative ease of the test, looking at blood under a microscope, this can be a quick and very cost efficient way to confirm heartworms in a questionable patient.
