Green colored plasma discovered in a male blood donor: A cause for concern?

Abstract

The normal color of plasma is yellow, which is owing to the presence of factors such as bilirubin, hemoglobin, carotenoids, and iron transferrin. We recently came across an interesting case of greenish colored plasma in our blood bank. An extensive literature survey revealed that our conspicuous finding was not an isolated one and that similar such rare incidents have been reported in the past, on a sporadic basis. Several diverse reasons have been attributed to the peculiar greenish color like the presence of high ceruloplasmin levels, Pseudomonas aeruginosa infection and so on, but they were ruled out in our case. We thus, report our finding of greenish colored plasma in an otherwise healthy donor because of the rarity of its occurrence and also, to allay any sense of fear or alarm that an encounter may raise in the blood bank staff.
