For those of you that progesterone test, the results are usually back the following day aren't they?  My question is about testing over a weekend.  Obviously the Thursday's blood sample will come back Friday and Friday's blood sample I presume will come back Monday, would that be right?

They are open on Saturday so sample sent on Friday (as long as it gets there for Saturday), you will get the results on Saturday :).

Idexx lab phone you the day they test the blood. Does your vet do a courier service or are you able to take the blood to a lab yourself? The Friday/Monday scenario might be too late for some bitches.

Oh that's brill!  Much better than I thought as I was worrying about those days in between. Thanks Noora!

I have had the blood taken on a Friday and sent it off myself immediately (always have a morning appointment) and received the results on a Saturday.
