I have been diagnosted with low b12 (185) in 2009, since I had no macrocytose, my GP refused any further investigastions.
Recently I decided to continue the battle alone; I have :
slight anemia (11-12 Hg) ;normal MCV
Low iron and ferritine ;normal B9.
antibodies anti parietal cell weak positive.
Slight non-atrophic gastritis .
Partial duodenal atrophy
Biopsies showed rare HPylori bacteria,but blood Antibodies negative,stool test negative !!!!
What could it be? any similar case ??
