Megaloblastic megakaryocytes may be seen with abnormally large and polylobated nuclei, sometimes with detached lobes and absent cytoplasmic granulation. Lack of a validated B12 absorption test hampers accurate diagnosis of pernicious anemia as the cause of B12 deficiency and clinical investigations related to all causes of B12 malabsorption.92 One possible test that shows promise, the Cobasorb test, is based on the measurement of the change in holoTC following oral administration of nonradiolabeled cobalamin.82,93,94 An alternative approach has been described using accelerator mass spectrometry to quantify 14C in the blood following an orally administered dose of [14C]-cyanocobalamin.95, In absence of any test for B12 absorption, definitive diagnosis of pernicious anemia is problematic and depends on the demonstration of circulating antibodies to intrinsic factor and gastric parietal cells.

For diagnostic purposes, the so-called blocking type, directed against the B12 binding site, is measured, as this type not only is highly specific for pernicious anemia but also is the species present in 70% of patients.96 Antibodies to parietal cells, although present in 90% of patients with pernicious anemia, are less specific, as they can occur in simple atrophic gastritis and in autoimmune thyroid disease.97.
