  Samples must be taken in a tube containing perchloric acid (PCA).

  NuTH requests: contact the metabolic lab (or specimen reception out-of-hours) for a tube.  Tubes are available on some GNCH wards.  They must be stored upright at 4^oC.

  Ensure patient details are hand-written on the tube.  Do not attach a label to the tube.

  External laboratories: contact the metabolic laboratory for a sample collection protocol.
