Final answer:
In pernicious anemia, parietal cell antibodies would be elevated, indicating the autoimmune cause of the B12 deficiency. Serum B12 would actually be low, MCHC could be elevated, and neuropathic symptoms are a potential manifestation of the condition.
Step-by-step explanation:
The condition known as pernicious anemia is characterized by the inability of the body to absorb vitamin B12 due to the lack of intrinsic factor produced by the stomach lining. The elevated level of parietal cell antibodies would be indicative of pernicious anemia.
These antibodies attack the cells that create intrinsic factor, leading to B12 deficiency. Conversely, serum B12 levels would typically be low, given that the condition involves poor B12 absorption. Instead, MCHC (mean corpuscular hemoglobin concentration) may be elevated due to the larger size of red blood cells in this type of anemia, and neuropathic symptoms may also be present due to the neurological impact of B12 deficiency.
