Conclusions

The important points to note, about homocysteine levels for Sample A and Sample B, from these Westmead results are:

  • Both samples showed significantly different trend
  • After an initial fall, Sample A increased to remain consistently above the limits
  • Sample B showed much less distinct initial increase that Sample A
  • Sample B reached a peak later than Sample A
  • Sample B fell rapidly after re-commencing oral B12
  • Last four A samples were destroyed by Mater Pathology.

The important points to note, about MMA levels for Sample A and Sample B, from these Westmead results are:

  • Both samples showed identical trend
  • Increased to remain consistently above the limits
  • Reached a peak, then leveled off
  • Fell rapidly after re-commencing oral B12 on 13 November 2006
