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

As I mentioned in my previous post, Chet, it depends on what you want to do with it.  If you are measuring protein, you probably won't have a problem it you separate the serum and clot.

One interesting thing with CSF.  If the person has microorganisms in the CSF, the organisms will eat the sugar and give you a little lower value.  The bodies will stack up and give you a little higher protein level.  Anyway, that is what we followed several decades ago.  Maybe things have changed.

Hapsters,
  One more question regarding the blood/serum sample that I have.  If refrigerated, how
long is it good for? (poor grammar).  I realize the cells will start lysing after a while but the
serum.....?????

  Thanks in advance,

Chet Harbut
