• There are no laboratory findings associated with the diagnosis of melanoma. Measurement of serum LDH may be considered for follow-up among patients who have been diagnosed with stage IB-IV melanoma.^[1]

• For patients with stage IB-IV melanoma, measurement of serum LDH may be considered every 6-12 months.^[1]
