It is used in evaluation of individuals with phenotypes associated with mild cystic fibrosis, congenital bilateral absence of the vas deferens (CBAVD), idiopathic pancreatitis, bronchiectasis; to confirm CBAVD diagnosis in infertile males; and to determine poly‑T status in individuals positive for the R117H mutation.
