Back in February I wrote about some of my experiences with “Living with an actual closed loop“. Time has ticked by, it’s now been 4 months since my last bolus, and I’ve just come back from a meeting with my endocrinologist. To re-cap: I have my AndroidAPS setup tuned fairly well (and using Fiasp in …
The HbA1c blood test is one that most people with diabetes are familiar with, at least to some extent. It measures the proportion of haemoglobin in our blood that has bonded with glucose, and is regarded as an indicator of your average BG levels over the preceding 3 months. “What’s your HbA1c?” is a question …
Standard Deviation, Time in Range, HbA1c, etc. Do they correlate in any way? Sure they give us information about how our blood glucose levels have been tracking over the previous few months. But most of us only look at the latest figures. I showed my own latest data in yesterday’s “What’s normal?” post. In preparing for my latest endocrinologist …
So another quarter has rolled around, and another blood test has been done. Here’s an analysis of my last 90 days of CGM data. This goes back to mid-December 2019 (so includes Christmas/NY). Compared with lab HbA1c Each day is different, but the above data is an average over the last 90 days. For the …
As I posted recently, my CGM data has been estimating my HbA1c will be 5.2% (which it was: 33 mmol/mol). However while Sugarmate also calculated an estimated HbA1c of 5.2%, its “GMI” value was 5.8%. I’ve always struggled to comprehend what GMI is meant to indicate. What is GMI? It turns out that “GMI” (Glucose Management …
There has been a lot of talk about TIR (Time in Range) and SD (Standard Deviation) being more useful measures of glycaemia than HbA1c. Looking back at my own experience I can see an issue relevant to this. I should reiterate: HbA1c only indicates what your average BG was. It says nothing about how wild …
