ASH Announces 24 Institutions Selected for Duffy Status Health Equity Project
Institutions across the United States will participate in a project to establish new blood reference ranges for Duffy status
(WASHINGTON, May 15, 2024) 鈥 The 白小姐三肖三期必出一期开奖 (ASH) announces that 24 health and hospital systems have been selected to participate in the Absolute Neutrophil Count (ANC) by Duffy Status Project, which will redefine pediatric and adult ANC reference ranges by Duffy status and address a critical health equity concern. The project is funded by the Doris Duke Foundation as part of its Racial Equity in Clinical Equations initiative.
The Duffy-null phenotype is commonly found among people with African and Middle Eastern genetic ancestry, affecting approximately two of three people in the United States with this ancestral background. People with the Duffy-null phenotype may have a lower ANC, or white blood cell counts, which is used to determine risk of infection. While those with Duffy-null Associated Neutrophil Count (DANC) are not at increased risk of infection, they are often labeled as having neutropenia, a low white blood cell count that can lead to unnecessary, expensive, painful, and invasive testing.
Currently, ANC ranges considered healthy are primarily based on data from individuals of European and Asian descent and do not account for Duffy status. The exclusion of ANC reference ranges that include the phenotype can perpetuate systemic racism and lead to delayed or discontinued chemotherapy and medication, clinical trial exclusion, and unnecessary medical procedures.
鈥淭his is a critical health equity issue that we need to address, and I鈥檓 proud that ASH and these esteemed health care institutions are working together to educate health care professionals, clinical trialists, and the public about the implications of DANC,鈥 said Mohandas Narla, DSc, ASH president, and distinguished scientist at New York Blood Center Enterprises. 鈥淩ace and ethnicity are not biological facts and are only used as a proxy for this research because this phenotype is most commonly found among those with African and Middle Eastern genetic ancestry. Beyond the implications of this effort for hematology, we are excited to be part of the larger Doris Duke Foundation initiative to re-examine if uses of race in clinical algorithms are grounded in current evidence.鈥
鈥淭oo often, differences in scientific observations about a biological phenomenon are attributed to race, with potentially detrimental consequences to patients,鈥 said Sindy Escobar Alvarez, PhD, program director for medical research at the Doris Duke Foundation. 鈥淭esting for Duffy status recognizes that race is a poor predictor of low neutrophil counts that can lead to overdiagnosis of neutropenia in Black patients and preclude Duffy-null individuals from participating in important clinical studies.鈥
The project will examine ANC of pediatric patients based on Duffy status along a range of age brackets, as well as adult patients aged 18 and older. Project sites will capture 200 de-identified samples from each pediatric age bracket to establish new reference ranges. Institutions will reconsider adult reference ranges specific to their organization. The results of this work will have broad implications across health care systems.
ASH-awarded Duffy Project Institutions:鈥
- Atrium Health Carolinas Medical Center

- Boston Medical Center
- Children鈥檚 Hospital of Philadelphia
- Children鈥檚 National Hospital
- Icahn School of Medicine at Mount Sinai
- Johns Hopkins University

The ANC by Duffy Status Project is supported by the Doris Duke Foundation. This work is in addition to ASH鈥檚 application to the National Center for Health Statistics鈥 ICD-10-CM Coordination and Maintenance Committee to establish new ICD-10 Z codes 鈥 the system by which health data such as diagnoses are recorded in electronic health records 鈥 for Duffy phenotype status. New Z codes will enable more accurate documentation, prevent unnecessary testing, and augment research. These new codes, included in the FY 2025 Hospital Inpatient Prospective Payment System proposed rule, are expected to be available for use starting October 1, 2024.
