Required section · Section 6 of 6
What the framework supports and what it cannot settle
ARC is primary, interpreted with the degree of anemia and the declared same-specimen timing. MCV, RDW, and positively observed morphology organize a focused differential without diagnosing a cause.
Low ferritin and TSAT support restricted iron availability; completed iron studies shift the next action to the remaining question, not a duplicate iron domain. When timing, stability, or needed context is missing, state that limitation rather than force a classification.
