Major criteria include petechiae respiratory insufficiency and central nervous system depression not fully explained by hypoxemia.

Minor criteria encompass tachycardia fever retinal changes jaundice renal dysfunction anemia thrombocytopenia elevated ESR and fat macroglobulinemia. A diagnosis is supported when at least one major criterion is present together with a minimum of four minor criteria.
