| Abstract: | Serum folate and vitamin B12 were measured in 171 healthy children under 14 years of age, 30 normal adults and 30 samples of normal cord blood. All the 171 children had been supplied with adequate folic acid and vitamin B12 before measurements. The results -were: 1. The lower limits of normal serum folate values were 6.1 nmol/L under 4 years, 8.4 nmol/L at age of 4-14 years and 5.0 nmol/L in adults. 2. The lower limits of normal serum vitamin B12 values were 459 pmol/L under 1 year and 107 pmol/L at age of 1 year to adults. |
