My recent B12 result was:

Vitamin B12 Binding Capacity 151 pg/mL Range: 650 - 1340 pg/mL

I don't know what this means. Never heard of "binding capacity." Been taking Jarrow B12 on an empty stomach. Big doses (1,000-10,000 mcg). My last B12 was nice and high, near 1000 if I recall. Puzzled. Am I all of a sudden not absorbing B12? My doctor is concerned because I am mildly anemic, as follows:

WBC 7.6 Thousand/uL 3.8 - 10.8 Thousand/uL
RBC 3.71 Million/uL 4.20 - 5.80 Million/uL
Hemoglobin 11.9 g/dL 13.2 - 17.1 g/dL
Hematocrit 35.2 % 38.5 - 50.0 %


Not doing too well today because I just had (unrelated) surgery on my arm. I'd be grateful if someone could explain. Thanks.
