Question: 3 patient samples were run against a 5.0 mmol/L glucose standard using a hexokinase method measured at 340 nm. The standard was run in duplicate. A blank was run. A control was run. The following results were obtained: Identification Standard 1 Standard 2 Control Patient 1 Patient 2 Patient 3 Absorbance 0.312 0.306 0.400 0.301 0.701 1.624 1. Calculate the difference from the mean (estimation of precision) of your 2 standards. 2. If the method requires the standards to be within 10% are the standards acceptable? 3. Calculate the value of your control based on the mean of the absorbances of your standards. 4. If the range for your control is 5.2-6.8 mmol/L is your control acceptable? 5. Calculate the values for the three patient samples. Report the acceptable values. The linearity of the method is 2.0-20.0 mmol/L.
