Serial Blood Count Study

Description

The objective of the Serial Blood Count Study is to determine the utility of home monitoring of white blood cell (WBC) and absolute neutrophil counts (ANC) to diagnose cyclic neutropenia and distinguish between cyclic and severe congenital neutropenia (SCN). A new home monitoring device called Athelas One was granted an FDA 510K Class 2 clearance for evaluation of white blood count (WBC) and absolute neutrophil count (ANC). The investigators believe this device provides a unique and extremely valuable opportunity to for diagnosis of these diseases.
