What do I make of this? I took a fasting test today and it read 8.3. Alarmed, as I have never known it to be over 7.6 and even then only occasionally, I took it a second time and it was 5.8. Is the meter at fault I wonder [it's a codefree]? As I have an annual review for hypertension coming up very soon and they always ask for blood tests for that and include the HbA1c plus a cholesterol test, I feel somewhat apprehensive. Any ideas as to why I should have these totally different readings?
