The origin of ferritin reference intervals: a systematic review.

Iron deficiency is a highly prevalent condition, which contributes to unnecessary morbidity, mortality, and health inequity. A serum ferritin concentration of less than 30 μg/L has a high specificity and sensitivity for diagnosing iron deficiency in adults, but the laboratory reported lower limit of normal (LLN) is typically lower. These LLNs might not be rooted in rigorous scientific evidence and might be contributing to structural underdiagnosis of iron deficiency.

Defining ferritin clinical decision limits to improve diagnosis and treatment of iron deficiency: A modified Delphi study.

Background: Iron deficiency is highly prevalent worldwide and is an issue of health inequity. Despite its high prevalence, uncertainty on the clinical applicability and evidence-base of iron-related lab test cut-offs remains. In particular, current ferritin decision limits for the diagnosis of iron deficiency may not be clinically appropriate nor scientifically grounded.

Effectiveness of Community Treatment Order in Patients with a First Episode of Psychosis: A Mirror-Image Study.

Objective: Poor adherence to antipsychotic medications is strongly associated with psychotic relapses and hospitalizations. This may hinder patients' ability to function, particularly in a first episode of psychosis (FEP). Poor adherence to treatment may be due to poor insight that can alter the capacity to consent to care, including pharmacotherapy.
