[ocular toxocariasis] Any established ELISA Lab

[Huh Sun]

Recently there was clinically suspected ocular toxocariasis in my 
University Hospital. I did ELISA with positive result. However, it was 
done with normal serum.  In Korea, there is still no case report of 
visceral larva migrans.  Therefore, I would like to request ELISA with 
positive serum. If any one or any Lab can do ELISA for toxocariasis, 
please let me know it. 

More detailed info is in below address.
