Conclusions

The objective of THE MMA EXPERIMENT was to investigate the quality of methylmalonic acid assays performed by these laboratories:

  • Mater Pathology
  • Queensland Health Pathology Service (QHPS)
  • NSW Biochemical Genetics Service at The Children's Hospital Westmead (CHW)

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.
