I'll follow your link and see what comes up.
However, being a lazy person, do I need (yet) to monitor all those other levels you speak of?
Another (growing) concern about ketosis, or not knowing when it occurs, is danger of hypoglycemia. Not that in itself can be a danger except it can happen without warning which may happen at some critical juncture.
I test myself 4 times a day, and when I take an average across all 4 sets of readings, I get a result that is close to my HbA1c. The 4 readings I take a (a) fasting (FBGL) before breakfast, (b) Pre-meal (just before my major meal (c) 2 hour PP (2 hours after eating to see how the sugar and simple carbs have spiked me and (d) 4hr PP (4 hours after eating to see how proteins and fats have affected me. This is also generally how I will remain for most of the night due to the way my meds work)
Recently, to save strips for dealing with hypo's, I have dropped the FBGL since it is now fairly static.
This testing regime allows me to see how my meals affect me, and allows me to tweak ny medication and foods.
I also use 2 meters in parallel in each test, and this gives me confidence in how true my meters are. It can detect a false reading or a misread, it can detect the inevitable change when changing to a new batch of test strips, and recently it detected when one of my meters started reading high due to a flattish battery.
You can organise how you want to test. There are no fixed rules. I discussed my regme with my GP and the DSN, and they agreed to fund one of my two meters. I self fund the other.
As regards hypo's, most people get indications when their bgl drops too low. For me it is visual disturbances, and crabby demeanour (see my Avatar). There is a very good hypo awareness course online and free . Go to DCUK main menu and look for it. I completed it and on the very same day I bought some glucotabs in Boots, and promptly had my first ever hypo.
While hypo can occur even in 'normals' it is only really a concern if you are on either insulin or a drug like Gliclazide. Metformin alone is much less likely to give any serious concern. As a T2 on orals, which I assume you are, then even if one occurs, it is unlikely to be a major event, and the body is very good at finding ways to protect us. The night before last I had a reading of 3.6, which is technically in hypo land, but I had a cracker, went to bed, and woke up with reading of over 5.8 I have only once had to use a glucotab to deal with a hypo condition, and that was only bcause the DVLA insist that my bgl is over 5.0 before I attempt to drive, and I had an emergency that needed me behind the wheel
