Serum immunoconglutinin levels in healthy subjects, malaria nephrosis and other conditions.

Serum immunoconglutinin (I-K) levels were estimated and compared in 189 normal school children, ninety blood donors, eight-seven nephrotic children, twenty-eight nephrotic adults, twenty-five falciparum malaria children and 126 miscellaneous patients. Low levels (1/32 or less) were recorded in 75.1% of normal school children and 68.9% of blood donors. Similarly 95.4% of nephrotic children and 71.4% of nephrotic adults had low titres. The trend was the same in other disease groups in which 88.0% of falciparum malaria children and 65.1% miscellaneous patients had low titres. The relevance of the I-K levels obtained in the study groups is discussed.
