Abstract:
Objective To explore the application value of the detection of vitamin B12 (VitB12 ) ,folic acid (FA) and four iron met-abolic indexes including serum ferritin (SF) ,transferring (TF) and total iron binding capacity (TIBC) and serum iron (SI) in the diagnosis and differential diagnosis of anemia .Methods 126 patients with anemia and 30 healthy controls were enrolled from Janu-ary to May 2013 and determined serum VitB12 ,FA ,SF ,TF ,TIBC and SI levels for conducting the comparison with each other . Meanwhile ,the patients with anemia were extracted bone marrow to carry out ferric stain and morphological test ,their detection re-sults and the results of above-mentioned serological markers determination were performed the comparison of the diagnostic accord-ance rate .Results The serum levels of various iron metabolism-related indexes had significant differences between the anemia group and the healthy control group (P<0 .05) ,and various different kinds of anemia had their comparatively specific serological characteristics .In 126 cases of anemia ,the diagnostic accordance rate of the bone marrow examination was 82 .5% ,which was sig-nificant higher than that of the serological examination(69 .8% )(χ2 =5 .600 ,P=0 .018);nevertheless ,in 23 cases anemia unable to determine the diagnosis by bone marrow examination ,the diagnostic accordance rate of the serological examination was 82 .6% (19/23);the inconsistent rate of the two examinations was 25 .4% (32/126) .Conclusion The bone marrow examination and the sero-logical examination have different emphasis points for the anemia diagnosis and have their own advantages ,which cannot replace each other .Their combination use has certain clinical value in the differential diagnosis between iron deficiency anemia (IDA) with anemia of chronic disease complicated with iron deficiency (ACD/ID) ,myelodysplastic syndromes (MDS) ,megaloblastic anemia (M A ) and mixed cellular anemia .
