  • Provided very significantly erroneous results for vitamin B12 and homocysteine.
  • Cite a very significantly low "normal" range for vitamin B12.

Queensland Health Pathology Service:

  • Provided significantly erroneous results for methylmalonic acid.
  • Took up to 36 days to produce results when tests are performed weekly.
  • Their reports did not contain any comment about the excessive methylmalonic acid levels.

Pacific Laboratory Medicine Services - Royal North Shore Hospital:

  • Provided very significantly erroneous results for homocysteine for Series 1.
  • Provided reports with many incorrect sample dates.
  • Refused to release the second Series 1a results because I refused to give them an assurance that I will not identify their lab if I publish the results.
