| Abstract: | The correlations between the deoxyuridine-suppressed value and some conventional haematological parameters (Hb concentration, red cell count, MCV, total white cell count, red cell folate level and serum vitamin B12 level) have been investigated in 40 patients with megaloblastic haemopoiesis due to folate or vitamin B12. deficiency. The only statistically significant correlations found were (a) an inverse correlation between the deoxyuridine-suppressed value and the Hb level or red cell count in both the folate- and vitamin B12-deficient groups and (b) a direct correlation between the deoxyuridine-suppressed value and MCV in the vitamin B12-deficient group. The results indicated that the deoxyuridine-suppressed value was a better index of the magnitude of the disturbance in red cell production induced by folate or vitamin B12 deficiency than either the red cell folate or serum vitamin B12 levels. |
