Hi, just wondering if anyone has had their Active B12 tested via this hospital please?
My tub has arrived today ( presuming my doctor supplies the yellow top serum tube) and it says before shipping it is recommended specimens be removed from the clot. serum may be shipped ambient ( maximum 16 hours in transit) at + 2-8C ( wet ice) -stable for up to three days or frozen (dry ice).
Am a bit confused about this, so thought I'd ask on here before having to contCt the hospital again on Monday.
Thanks very much...
