What are the sample requirements for the DQa test at RFU ?
20-30mls of blood collected in lavender top (EDTA additive) tubes mixed well before posting (tubes rolled end over end about 10 times). Not refrigerated/frozen. You can have the blood drawn at TDL (on Wimpole St, two doors from Dr Gorgy). You can arrange to get a post pack from Dr Gorgy/TDL and have the blood drawn at your GP (or local hospital) on Monday/Tuesday afternoon and then post it back to TDL special delivery before 9am so that they add it to their fedex pick up on Tuesday/Wednesday in time to get it to Chicago within 48 hours. However, I believe as the sample does not depend on the cells being alive, the duration of transit time to Chicago should be less critical than for other Chicago tests.
