Request an SI Genetic Test Kit

Order an SI Genetic Test in High-Risk Patients:

  • Genetic Sucrase Deficiency will exist in a subset of patients with low sucrase activity regardless of lactase results1
  • Determine whether genetic etiology may be a factor1
  • When sucrase activity is < 25 μM/min/g
  • If disaccharidase assay results are not available for patients with long-term chronic diarrhea and/or abdominal pain and other common GI disorders have been excluded
  • A positive genetic test supports the diagnosis of GSID. The test evaluates for the presence of 37 known pathogenic variants. A negative test result demonstrates the absence of one or more of these variants. However, other unidentified pathogenic variants may exist, so a negative test is not conclusive for absence of the disease.

  • SI Genetic Test Request Form and Patient Application & Consent Form
  • Collection devices to obtain the genetic samples via swabbing of the inside of the cheek
