Hi, Rima. Thank you for your question to the forum.
While the ranges for a diagnosis of diabetes vary depending on whether the test is done
as a fasting or random glucose (the presence or absence of symptoms will also aid
the diagnostic process), importantly there can be a difference in results between
blood taken from a finger prick and that taken via a formal blood test
(with blood taken from the arm).
Care also needs to be taken in interpreting finger prick blood glucose levels as sticky
fingers or dirty hands can affect the result. It’s also important to make sure that the
test strips are in date and meter calibrated properly, as this will also affect the
accuracy of the reading.
Frequent urination and fatigue can be indicative of diabetes; however there are
other potential diabetes-related signs. These include excessive thirst, and weight change.
A correct diagnosis is essential. At this stage we would suggest that you discuss
your concerns with your General Practitioner.
