What is hypERglycaemia?
- when blood glucose conc increases and stays high
- kidneys can not reabsorb all the glucose so some is excreted in urine.
What is hyPOglycaemia?
When too much insulin injected produces a dangerous drop in blood glucose levels
Causes of Type 2 diabetes

What experiment is used to determine the concentration of glucose solution?
ColOrimetry
How do determine the concentration of glucose in a urine sample? (colorimetry)
- Do a serial dillution of different conc of the urine.5 test tubes)
- Add Quantitative Benedicts reagent is added to see if it contains glucose
- from blue solution it goes colourless
- it is placed a colorimeter
- used to measure the light absorbance
- make a calibration curve with results-concentration of glucose(x) and absorbance (y)
