title: Plasma discolouration due to sun-tanning aids.
abstract: The ingestion of the new sun-tan capsules 'Orobronze' containing the carotenoid derivative canthaxanthin discolours plasma orange. This is noticeable in the plasma of blood donations received 4 days after starting the capsules and continues for a further 4 weeks after finishing the course. This cause of plasma discolouration should be recognised as it was found to mask haemolysis within a plasma sample.
