Guest guest Posted October 14, 2007 Report Share Posted October 14, 2007 Is the Porphyrins test the same as the fractionated porphyrins test? I actually shook the specimen vigorously in the tube to mix the preservative in!!! This was not a 24 hour urine collection but the first in the morning sample. Went to the Paris lab. Did I just botch up my test results? Thanks. Quote Link to comment Share on other sites More sharing options...
