This article describes hematologic, nutritional, allergic/asthmatic conditions, lead screening, and management of these among immigrants and refugees. Some of these conditions present more frequently or differently in the newcomer population. Early identification and treatment are key to improving health outcomes. Screening and treatment suggested in this article are based on current guidelines and are intended for primary care providers who are caring for refugee and immigrant patients, especially within a medical home. Special considerations include level of education, instruction, demonstration, and cultural humility.
