[Comparative determination of microalbuminuria using radioimmunoassay and kinetic nephelometry in children and adolescent with and without Type-I diabetes mellitus (IDDM)].
In 73 healthy (group I) and 32 children and juveniles with insulin dependent diabetes mellitus (IDDM, group II) urinary albumin excretion is determined by radioimmunoassay (RIA) and kinetic nephelometry. Intention of the study is to examine, if the kinetic nephelometry is--as observed in adults--a suitable method also in children and juveniles to detect microalbuminuria (greater than 30 mg/d). In both groups albumin excretion is observed in every urine sample when measured by RIA. Because of it's higher threshold kinetic nephelometry detects albumin excretion only in a part of the urine samples. The correlation between the two methods is very high (r = 0.905, p less than 0.001, n = 174). So kinetic nephelometry is not suitable to determine reference values. But as a faster and possibly more specific method than RIA nephelometry is a very effective way for a screening of microalbuminuria also in children and juveniles.
