If the proportion of red blood cells
(haemotocrit level) is very high (over 55%)
or very low (under 30%), this could distort
the test results.
•
Studies have shown that electromagnetic
fields can affect the test results.
Do not perform tests in the immediate
vicinity of devices that could emit strong
electromagnetic radiation (e.g. microwaves
or other active mobile wireless devices).

the results seem unusual, it can be useful to be familiar
with the symptoms of high and low blood glucose.

you show symptoms of high blood glucose, consult
your doctor without delay.
