• Serum IgE levels and the radioallergosorbent test measurements (RAST) for cow's milk proteins were determined in 75 consecutive children with recurrent abdominal pain (RAP) of undetermined cause and 50 consecutive controls of similar age and sex without evidence of RAP, allergy, or parasitic infestation. No significant difference in serum IgE levels and RAST (cow's milk protein) results was demonstrated in children with and without RAP.
