Deciphering the reasons for milky-white blood donor plasma.

Donors who eat a fatty meal before donating blood are known to have an increased level of plasma triglyceride concentrations for several hours. This may contribute to "milky-white" appearance of their plasma samples. We herein report the case of a blood donor who gave a history of the intake of a fatty meal, on the night prior to donation. This was affirmed by his serum lipid concentration done on the following day and on repeating the same subsequently after two weeks of donation respectively.
