Diagnosis

If you think you or your child may have toxocariasis, you should see your health care provider to discuss the possibility of infection and, if necessary, to be examined. Toxocariasis can be difficult to diagnose because the symptoms of toxocariasis are similar to the symptoms of other infections. A blood test is available that looks for evidence of infection with Toxocara larvae. In addition to the blood test, diagnosis of toxocariasis includes identifying the presence of typical clinical signs of VT or OT and a history of exposure to cats and dogs.
