Conclusions

Gross Errors in Results

  • Two labs out of three gave very significantly erroneous results for homocysteine

Errors in Documentation

  • One lab supplied documentation with dates that did not match the samples
  • One lab gave many incorrect sample dates in pathology reports

Citing Grossly Erroneous "Normal" Range

  • Three labs cite a normal maximum very significantly above the safe level for homocysteine

Refusal to Release Results

  • One lab refused to release the Series 1a results because I will not give them an assurance that I will not identify their lab if I publish the results

Incorrect Handling of Samples

  • One lab sent out three samples frozen in SST tubes, against the tube manufacturer's advice, invalidating the results.

Loss or Destruction of Blood Samples

  • One lab "lost" two blood samples
  • One lab "lost" 29 blood samples
  • One lab deliberately destroyed at least four blood samples

Response to Complaints

  • One lab responded to my complaints with a threat of legal action
  • Two labs strongly defended that lab
  • No lab offered to investigate my complaints
