Specimen Requirement |
The sweat test is offered only to patients at an appropriate criterion: to increase the likelihood of collecting an adequate sweat specimen, sweart chloride testing can be evaluated in asymptomatic newborns with a positive newborn screen result or positive prenatal genetic test when the infant is at least ten days old, greater than 36 weeks gestation, and weighs >2kg. Sweat chloride testing should be performed as soon as possible at or after 10 days of age life, ideally by four weeks of age. Sweat collections acquired in newborns >3.5kg (versus >2kg) improve specimen acceptability rates by 25% and should be considered when assessing the risk of a quality not sufficient (QNS) collection versus the need to obtain diagnostic information. Sweat minimum volume: 50 uL |
