Each week, I asked Sullivan Nicolaides Pathology to collect four tubes of my blood, and distribute them, as follows:
- One tube for in-house analysis of serum B12
- One tube for in-house analysis of total homocysteine (tHcy)
- One tube for send out to QHPS
- One tube for send out to Mater Pathology
A copy of the following diagram, illustrating the procedure, was provided with each request form following the loss of the samples for 17 July and 14 August.
