- A cholesterol screening has reported Toms blood serum contains 50mg/dal HDL and 180 mg/dal LDL and a total cholesterol of 255. What is the LDL/HDL ratio? Is this value considered in the healthy range?In the experiment performed for the determination of cholesterol, the function of the calibration curve obtained using 25-400mg/dL standard cholesterol solutions was determined as y= 0.0009x. If the absorbance of the serum sample is determined as 0.28, what is the amount of cholesterol in the sample, in mg/L?a) What are the methods used for cholesterol determination? Explain the basis of the method you used in your experiment by writing.b) In the experiment conducted for the determination of cholesterol, the function of the calibration curve obtained using standard cholesterol solutions of 25-400mg/dl was determined as y= 0.0009x.Since the absorbance of the serum sample was determined as 0.28, how many mg/L is the amount of cholesterol in the sample

What are the implications of using a turbid serum sample?Given that the normal range for serum protein is about 7 g/100ml and albumin is about 4 g/100ml, what clinical conclusions can you draw from the following samples A-C? If samples are not normal, what protein fraction is increased/decreased and with what disease is this protein pattern likely to be associated? Sample A: total protein = 14 g/100mlalbumin= 8 g/100 ml Sample B:total protein = 5.8 g/100ml albumin = 4 g/100 ml Sample C:total protein = 3.5 g/100mlalbumin = 2g/100 mlA dosage of 3 mcg/kg/min has been ordered for an 87.4 kg adult.

- The amount of calcium in physiologic fluids can be determined by a complexometric titration with EDTA. In one such analysis, a 0.100-mL sample of blood serum was made basic by adding 2 drops of NaOH and titrated with 0.001 M EDTA, requiring 0.238 mL to reach the end point. Report the concentration of calcium in the sample as miligrams of Ca per 100 mL. (Ca = 40.078 amu).From the following data, find the % (w/w) cream of tartar (KHC4H406, MM=188): Wt of sample = 1.4160 g NaOH titrant used = 20.87 mL HCI used for back titration = 1.27 mL 1.00 mL HCI 1.12 mL NaOH 1.00 mL HCI A 0.01930 g CaCO3 89.08% (w/w) 87.12% (w/w) O 47.75% (w/w) O 95.59% (W/w)The order is for Coumadin 7.5mg po daily.
