A febrile patient with known or suspected sJia must be considered for<unk><unk>  if: * Ferritin >684 ng/ml and any 2 of the following: * Hemoglobin <90g/L (in infants <4 weeks: <100g/L) * Platelets <100 x 109/L * Neutrophils <1.0 x 109/L * Fasting triglycerides ≥3.0 mmol/L (i.e., ≥ 265 mg/dl) * Fibrinogen ≤1.5 g/L In addition, other specific markers of<unk><unk>  (e.g. soluble CD163), and lymphocyte<unk>  (e.g. soluble IL-2 receptor) can be helpful. NK cell function analysis may show depressed NK function, or, flow cytometry may show a depressed NK cell population.
