Hi Anyone had these done? Posted on PA forum but no responses. Hoping to find somewhere a bit cheaper than BH and Medichecks if that's possible. Otherwise would be interested to hear who you used and whether result was helpful to you. This is not for me, it's for my husband. He has had a lowish B12 result and we have done an active B12 which was fine but lowish again. Just want to get all the tests done that can be affected by supplementing before we try that. Thank you.
