We are currently unable to source Cobalt57 labelled vitamin B12 to carry out our RIA B12 assay, as our supplier has not been able to receive any Co57 from Russia where it is produced.
From today, our Dunedin laboratory will not be able to carry out B12 testing. We will instead subcontract this testing so you may notice a slight delay with reporting.
We are trying to find an alternative source for the tracer and are also validating a new B12 assay. We aim to complete the method validation this week, and will resume in-house testing at that time.
We apologise for any delay with results, and thank you for your patience and understanding. If you have any questions, please just contact your local laboratory or Territory Manager.
