Clinical chemical methods for the routine assessment of the vitamin status in human populations. Part I: The fat-soluble vitamins A and E, and beta-carotene.
Reliable HPLC methods for the routine determination of vitamin A (only retinol, not the ester) of beta-carotene and of vitamin E in plasma are described. The results found in 150 blood donors are reported; the correlation of the concentrations of vitamin A with retinol-binding protein and of vitamin E with beta-lipoproteins are calculated.
