Double blind study of vitamin E compared to placebo in the prevention of anemia in the low birth weight infant during the 7th week of life: therapeutic study

Sephadex G-25 (Kernlute test) yields satisfactory results for the identification of infants at risk for BE and for estimation of the bilirubin binding capacity of the serum. In the presence of more than 2 mg/100 ml of conjugated bilirubin, the interpretation of the Sephadex G-25 test requires caution. Gel filtration through Sephadex LH-20 and chloroform elution of the free unconjugated bilirubin not bound to albumin seems to be a useful tool for eliminating interference by conjugated bilirubin, which is not chloroform-extractable.
