Indeterminant Interferon-γ Release Assays in Refugee Children with Splenomegaly, Uganda, 2020-2023.

We observed a novel association between splenomegaly and indeterminate interferon-γ release assays in refugee children 5-14 years of age in Uganda. Those demonstrating splenomegaly were 4 times more likely to have indeterminate results. Among refugee children 2-4 years of age, >10% had indeterminate results even without splenomegaly.
