Re: [HAPS-L] Longevity of blood/serum sample

["James S. Miller" <jamessm@xxxxxxxxxx>]

        I've kept defibrinated and anti-coagulated blood for 4-5 weeks, 
and still had plenty of intact RBCs.  I don't know what biochemical changes 
might have occurred, but the RBCs look normal.  After 1-2 weeks the plasma 
gradually gets redder as RBCs lyse and release hemoglobin, but there are 
still lots left after 4-5 weeks.  Eventually the whole thing will kind of clot.
        If there's any kind of bacterial or yeast contamination in the 
blood, it can go bad much faster.
