title: Infrared irradiance from phototherapy units and the effect on osmolality of serum and urine in term infants.
abstract: The osmolality of urine increased in 10 term infants receiving phototherapy. Phototherapy units made locally were likely to emit more infrared radiation than a unit available commercially, but both types led to falsely increased incubator thermometer readings. Interposing a 6-mm acrylic sheet prevents these effects.
