  • Page 14: System Description

    Section 1: Introduction 1.3 System Description Nanoduct is a complete, integrated system for inducing and analyzing sweat for cystic fibrosis (CF) diagnosis—all while attached to the patient. This reduces the possibility of intrinsic error and enables pristine samples to be obtained from neonates and analyzed in situ.
  • Page 15: Pilogel Iontophoretic Discs

    Section 1: Introduction Pilogel Iontophoretic Discs Pilogel discs are small (surface area 2.5 cm ) iontophoretic discs that are inserted into the electrode assemblies before iontophoresis. Designed especially for neonates, these discs have a pilocarpine concentration of 1.5% for optimum stimulation of the sweat gland, which also reduces the iontophoresis time to approximately 2.5 minutes.
  • Page 16: Induction/Analysis Module

    Section 1: Introduction Induction/Analysis Module The battery-operated electronic induction/analysis module controls the Nanoduct system. The module performs six separate functions: 1. Provides a timed and controlled current for iontophoretic sweat stimulation. 2. Measures electrical conductivity of the excreted sweat during the analysis phase.

  • Page 37: Interpreting The Sweat Test

    Section 3: Sweat Induction and Analysis 3.2 Interpreting the Sweat Test Units of Conductivity Electrical conductivity–essentially an electrical measurement–should properly be measured in siemens/cm. However, we use conductivity to indirectly measure electrolyte concentration. Since medical professionals are more familiar with standard chemical units (such as mmol/L) for concentration, the siemens/cm units have not been used for conductivity values in the practice of clinical chemistry, to prevent confusion.
  • Page 38: Diagnostic Ranges

    Section 3: Sweat Induction and Analysis The induction/analysis module is therefore programmed to make an average conductivity assessment by noting the time at which the first conductivity result is displayed, allowing a time lapse of 3 minutes and then commencing a 5-minute averaging period, after which the mean value is displayed. Diagnostic Ranges Using the data displayed in Fig 1, which show both sweat rate and conductivity variation with time after stimulation, the Nanoduct averaged value (over period C)

  • Page 61 Appendix H: Supplemental Information Cystic Fibrosis: A Brief Description of the Disease Cystic fibrosis of the pancreas (or mucoviscidosis) is due to one of the many known ‘inborn errors of metabolism’ that are fundamentally the result of aberrations in the structure of the genetic material. It is classed as lethal because of the very poor prognosis afforded to sufferers.
  • Page 62 Appendix H: Supplemental Information While the iontophoretic transport of pilocarpine into the glands has remained the universally preferred method of sweat stimulation to this day, the need for a simpler method of collection and analysis spawned the development of alternative procedures during the late 60’s and early 70’s. Principally among these were the cup-collection systems, which used electrical conductivity for analysis, and the direct skin chloride electrode system.
  • Page 63 Appendix H: Supplemental Information Development of the Nanoduct Neonatal Sweat Collection System During almost twenty years of successful deployment of the Macroduct Sweat-Chek System it began to be realized that a truly neonatal sweat test was needed, one that preserved the error-free anaerobic handling of the sweat sample employed in Macroduct, yet at the same time was particularly designed to meet the special requirements of the newborn infant during the first two weeks of life.
