Interference of Thiouracil in the Ferric Chloride-Sulfuric Acid Cholesterol Reaction

[摘要] Thiouracil, previously recommended as a preservative to be added to serum for butanol-extractable iodine determinations, inhibits the ferric chloride-sulfuric acid color reaction for cholesterol. The color inhibition may be eliminated by shaking the serum for about 5 min. with solid silver iodate prior to cholesterol analysis.
