If the concentration of a standard, the absorbance of that standard and the absorbance of an unknown solution are known, the concentration of the substance in plasma (unknown) can be calculated. Calculate the concentration of cholesterol from a fasting sample of my blood given that a 20 microliter sample of my plasma in 2.0 ml reagent gave an absorbance reading of 0.39, while a 20 microliter standard with a concentration of 200 mg/dl in 2.0 ml of reagent gave an absorbance reading of 0.49. Calculate my cholesterol concentration and tell me if it is in the normal range cited by Fox. Group of answer choices
