    • The present invention provides an aqueous cholesterol standard solution with a definite content of cholesterol, wherein it contains a detergent mixture of 10 to 90% of cholic acid and 90 to 10% of desoxycholic acid or of appropriate salts or derivatives of these acids.The present invention also provides a process for the preparation of this aqueous cholesterol standard solution, wherein a detergent mixture of cholic acid and desoxycholic acid or of appropriate salts and derivatives of these acids is dissolved in distilled water or in 0.9% aqueous sodium chloride solution, an appropriate preservation agent and/or a buffer effective in the pH range of from 7 to 9 optionally added thereto, and a definite, precisely defined amount of cholesterol is dissolved in the solution thus obtained, while stirring and warming to 40.degree. to 60.degree. C.
