• Increased rapidly after commencing oral B12 on 2 November 2005
• Fell rapidly to 323 pmol/L, after ceasing oral B12 on 10 February 2006
• Continued to fall at much slower rate
• Never fell below SNP normal range
• Increased rapidly after re-commencing oral B12 on 13 November 2006

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.
