Levels within therapeutic range: Treatment is likely effective with low toxicity risk
Elevated levels: Increased risk of toxicity; may require dose adjustment or Leucovorin rescue
Subtherapeutic levels: May indicate ineffective treatment or non-adherence
Consult a healthcare provider for personalized interpretation based on patient history and symptoms
