Hi @Alexdj & welcome to the forumHello I’ve been diagnosed with type 2 about 2months ago trying to control it with diet and exercise as my body wouldn’t agree with the metformin tablets what is the best way for me to test my blood to see if I’m going in the right direction
ThankyouWelcome. I couldn't get on with metformin, and ditched them after a couple of weeks. That was my decision - not my doctor's. Regarding testing, test just before eating, and again two hours later. The rise in your blood glucose shouldn't be higher than 2 mmol/L and should be less than 8.5 mmol/L. I hope that helps.
I also started just with Metformin 1a day eventually built it up to 4Welcome. I couldn't get on with metformin, and ditched them after a couple of weeks. That was my decision - not my doctor's.

Hi @Alexdj for me I found the old ways are the best.what is the best way for me to test my blood to see if I’m going in the right direction

Thankyou very helpfulHi.
In addition to what folks have said above, in my experience getting a grip of two different but complementary reasons for blood testing is useful.
The long-term "how am I doing" information comes from the HbA1c tests that the GP surgery will run (usually every six months initially). This gives an estimate (not an average) of what your BG has been over the last three months or so, although it's heavily skewed towards the last month. This test works by counting the numbers of a type of haemoglobin molecule in your red blood cells that have had a glucose molecule attached. As red blood cells live around three months or so, this gives an estimate of what your glucose levels have been doing in that time.
You can't do HbA1c tests at home, although you can pay for additional tests privately. I've never seen the need to do this. The test does have some margin of error (I've had personal experience of one HbA1c test being extremely wrong) but this should be comparatively rare.
Fingerprick tests, the sort you do yourself with a meter, are (again in my experience) most useful for testing the impact of various foods, activities, and situations on your blood glucose levels. This will show you what raises and lowers BG in the short term. Normally for testing around food, you take a baseline test immediately before eating, and then test again after two hours. You are not testing to see "how high you go". What you're really testing is how effective your insulin response was in dealing with the carb and resulting glucose in what ever you ate. That's why the ideal is that after two hours the second reading is back down to within 2mmol/l of the baseline. It will almost certainly have gone much higher in the interim, which is normal and to be expected. The peak is usually somewhere around 40-45 minutes after eating.
As an example, a small milky coffee on an empty stomach will take me from low 5s to 9.6 within 40 minutes, but I'm back to low 5s by one hour. This shows that my system is efficent at digesting the lactose in the milk (it probably helps it being hot) and also efficient enough to clear the relatively small amount of extra glucose out of my bloodstream within minutes. My system won't clear a more substantial glucose load within 2 hours, so I normally avoid eating carbs in that sort of quantity.
CGMs are really good at showing you what happens when you're not testing - eg when you're asleep, or driving, or whatever. My BG will rise and fall all the time not because of food, but because our livers are constantly making and adding glucose to the system to replace what's being used up by muscles and brain. There's little we can do to directly control what the liver gets up to, but it's good to be aware that while food is the biggest influence on BG levels, the liver is a player as well.
Best of luck.
