5. 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. Absorbance of the standard = 0.075; Concentration of the standard = 10.54mmol/L Absorbance = 0.83 mmol/L Convert your answer to mmol/L or S.I. using the conversion factor for glucose which is 0.055 Please show your computation.

A 38-year old man was admitted with a 3-day history of severe diarrhea with some nausea and vomiting. During this period his only intake was water. He was weak, unable to stand and when recumbent his pulse was 106/minute and blood pressure was 110/50 mmHg. On admission, his biochemistry results were: Analyte Result Reference range Na+ 129 135-145 mmol/l K+ 2.9 3.5-5.0 mmol/l Cl- 85 95-105 mmol/l HCO-3 18 21-28 mmol/l Urea 19 2.5-8.0 mmol/l Creatinine 160 40-130 mmol/l   2.
