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.
