Association between CBC parameters and serum vitamin B12
The association between vitamin B12 and CBC parameters was analyzed using Pearson’s correlation where our results revealed that there was a statistically significant correlation between Hb level and vitamin B12 level as shown in table 6. In addition, a statistically significant correlation was observed between RBC and vitamin B12 level (r= 0.311,P <0.001). Pearson product-moment showed there was a statistically significant positive correlation between serum B12 and PCV (R=0.192, P =0.021), B12 serum and PLT (R=0.193, P =0.025) while no statistically significant correlation was found with MCV (R= - 0.080, P =0.354) as illustrated in table 6.
