title: Detection of cystic fibrosis heterozygotes using the zeta potential reduction method.
abstract: Parotid saliva samples from cystic fibrosis homozygotes, heterozygotes and normal individuals were tested by the zeta potential technique for secretion factor in a double-blind experiment. There was no overlap between zeta potential reduction of the control group and the cystic fibrosis test groups, indicating that the zeta potential test may be detecting a unique component in saliva of cystic fibrosis genotypes.
