Serologic diagnosis has proven effective,particularly in ocular larval migrans (OLM).Aqueous humor elevated antibody titer specific for Toxocara spp. ,in comparison to serum levels,is considered diagnostic.Although serologic analysis can be useful,it is important to note that antibody titers may vary,depending on the location of the infection.A serum titer of 1:8 is considered significant for OLM;1:32 is significant for visceral (tissue)larval migrans (VLM).
