    • -Timed (ten minute window)
    • -ASAP: inpatient has 2 hour Turn around time (TAT) outpatient has one business day
  63. Why protect some specimen from light

  74. glycolytic acton is
    a process of red blood cells in vitro ad using glucose and other analytes form the liquid portion of the blood with time
  75. to prevent glycolytic action SST was invented.
    throxotropic gel migrates during centerfugation to block serum from cells. Serum separation tubes (SST) must sit for 30 minutes before centerfugation then centerfuge for 10-15 more minutes. bad for emergency situations where results are needed immediately
  76. PST bennefits
    plasma separation tubes only require centerfugation fast TAT 5-15 minutes instead of 45 or more as in SST.
