Using the RDL as the detection threshold (Figure S1 Panel H),
Table 2 shows that over 60% of APF+ individuals had detectable
levels of IgG to OV antigen in their urine. A lower proportion
(38%) of individuals who were OV+ and APF2 (matched controls)
had detectable levels of urine IgG to OV antigen. All eight (n= 8)
of the CCA patients who had urine samples had detectable levels
of IgG to OV in their urine.
