Question
  1. Using this formula Cu = Au    x    Cstd  / Astd

                                Where:  C = concentration

                                                 A = absorbance

                                                 U = unknown/sample

                                                 STD = standard

Compute for the glucose concentration of the patient’s sample.

(Note:   The standard reading in the video is quite very high, so I am going to give you a value for the standard which you can use for your computation)

Given:

Absorbance of the standard = 0.075

Concentration of the standard is mentioned in the video. = 10.54 mmol/L

Absorbance of unknown is in the video. = 0.083

Convert your answer to mmol/L or S.I. using the conversion factor for glucose which is 0.055
