Viapath is a company that have been offering the Active B12 test for many years and they are hoping to make the Active B12 and MMA tests more widely available for patients through a cost effective and easy to use channel.
Viapath is gathering patient feedback and insights to help them adapt and improve their tests via a short (5-10 minute) survey and would like to hear of your experience of getting, or not getting a diagnosis.
Do you live in the UK and have a few minutes to spare? Then please participate in this valuable project.
The survey is now closed. Thank you very much to all respondents, your help is much appreciated!
