my blood results have always come back in the afternoon the blood was drawn.
one exception was my first appointment for the CF blood draws, those took a day.
blood type, HIV, Hep and other hormone levels were all the same afternoon called back to me ( as long as i had blood drawn before 1030am, their drop off is 11) .
It may have to do with the clinic though. give your office a call to see how long they normally take. the office im at seems to label everything as Stat and i think their blood lab is just down the hall from the fertility clinic
