Hi. Some hematologists do these tests routinely, others don't. They are specifically ordered separate to the CBC and biochemistry.
If the copper level is low it can cause BMB appearances similar or even identical to MDS particularly RARS. High zinc levels can cause low copper levels. Similarly low B12 can cause anaemia but I'm not sure about the sideroblasts with B12 deficiency.
My ringed sideroblasts were 78% when my low copper level was discovered. The last BMB I had, after copper infusions, the sideroblasts had dropped but were still well above normal.
Hope this helps.
Regards
