Methemalbumin

**Definition:** A 1:1 molar complex of heme or hematin and albumin formed after the dissociation of methemoglobin into heme or hematin and globin in plasma. This complex, which imparts a coffee-brown color to plasma, occurs in hemolytic and hemorrhagic disorders. Its presence in plasma is used as a test to differentiate between hemorrhagic and edematous pancreatitis.
