Conclusions

The objective of the tHcy experiment was to investigate the quality of total homocysteine assays performed by these laboratories:

  • Sullivan Nicolaides Pathology (SNP)
  • Queensland Health Pathology Service (QHPS)
  • NSW Biochemical Genetics Service at The Children's Hospital Westmead (CHW)
  • Pacific Laboratory Medicine Service (PALMS)
  • Royal Prince Alfred Hospital Pathology (RPAH

This followed the discovery of very significant differences between laboratories during the serum vitamin B12 experiment.

The original serum B12 experiment is described in THE SERUM VITAMIN B12 INVESTIGATION.
