Hi Sharon,

Try Clinpath, they are part of the Sonic Healthcare group who I worked for for 9 years before becoming a full time Mummy. They have 2 collection centres in Adelaide city, one in Wakefield St and one in South Terrace. There should be no probs with getting a same day turn around for HCG, E2and P4, they are all done on an automatic analyser so only take a few hours. See if you can get your path request marked urgent or priority 1 so the blood doesn't get caught up in specimen reception with all the routine work going through.

Good luck!
