When do you carry out the test?
The test should be taken on an empty stomach, which means that you should not eat or drink anything for at least twelve hours before taking the test. If possible, take the test during the day or in a room with good lighting, so that you can better assess the colour variations in the test results.
Blood glucose levels are generally affected by various forms of medication, alcohol, diet, stress, elevated blood pressure, smoking, etc.
The following factors may influence the test results:
Physical factors: too high (>55%) or low (<35%) haematocrit levels, too high a concentration of lipids in the blood, hyperglycaemic-hyperosmolaric conditions, and glutathione of red blood cells.
Treatment: novaminsulfon and ascorbic acid in concentrations >0.4g /L and alpha-methyl dopa >0.2g/L, plus dialysis.
Usage errors: a small sample size (< 5–10µl), and an inadequate swiping technique.
Never take any medical decisions without consulting your doctor. This test is not reusable.
