      Do you know how to test for ketones? Please share more in the comments.
      I test when I have unexpected, or stubbornly high blood glucose that just won't go down. I also test when I feel sick. Testing, for me, involves putting urine on a strip, either by peeing directly or dipping the strip into urine. I may use about 2 or 3 strips in a year. When I test positive, I increase my insulin dosage to a "sick day" level, which can be anywhere from 125% dosage to 400%. I usually start with small increases in dosage, and work my way up until my blood glucose levels even out.

      I have a blood ketone monitor. It works just like a glucometer.

      Perhaps only the poets who love alliteration could love the phrase, “killer ketones.” The ungodly pain experienced is your body eating and devouring itself. 🥵 Ketones are relentless killers. Do not give the bad guys a chance.

      Hi, Marty. Does your specialist have a source for that claim? It makes little sense that ketones would rise faster than BG since the metabolic pathway is much slower. If there's a source, however, I'd look further into the claim. FWIW, I've been a Type 1 for over 50 years; I can't remember the last time I tested for ketones. I possess no ketone testing strips.

      It covers both. I prefer to have the the nasal version as I think it would be easier for someone else to administer.

      Do you have a non-expired glucagon prescription?
      I’ve been T1D for 60 years. As a child my mother didn’t like needles or injections so she just fed me when low. In college, explained use to dorm mates and classmates would’ve been a waste of time. Now married, my wife assumed the role of my mother and doesn’t like using needles on me either. I don’t have glucagon.

      Do you have a non-expired glucagon prescription?
      Yes, always have one or two nasal glucagon kits (Baqsimi) at home in easy to reach locations (ie at bedside and special container in living area) and always keep one with me when I go out ( along with glucose tabs or other simple carbs for treating LBS.). I apparently required injectable glucagon several times as a child and needed injectable glucagon only twice as an adult, both more than 15 years ago . More recently I needed my husband to give me Baqsimi after eating a difficult to dose for, high fat meal. The experience was terrifying so I don’t go anywhere without it now.

      I actually have 2 non-expired prescriptions. One for Baqsimi and one for Gvoke. I have not filled either of them because they’re $500-600 each.

      Same here. Been as low as 19 (struggling with a vacuum cleaner bag and refused to let it win) but was still able to swallow food. I did used the “red needle” as my husband refers to it once when I went low but was scheduled for surgery and couldn’t eat or drink anything. Only once in 26 years. Fortunate.

    If you use an automated insulin delivery system (e.g., Tandem with Control-IQ, Omnipod 5, Medtronic pumps with Auto Mode, etc.), how did your A1c change in the first 3 months of use?

    Do you dispose of used needles, syringes, lancets, and other sharps in a dedicated sharps container? For this question, "sharps container” includes heavy-duty plastic containers such as an empty laundry detergent bottle or plastic coffee container.

      Time-in-range is important, but since I think many of us want to be in a tighter range than 70-180, time-in-range is only so helpful. Actually looking at our actual numbers in reference to how high or low we go is more important than being “in-range”.

      My concern with time in range is that I could be in range 90% but my average could be 170 which to me is way too high. With my previous, Medtronic, pump I was averaging 131 over 90 days, now with control Iq I am averaging 151. Control Iq is not all it is made out to be.

      I said, “A little important.” As Derek West said, I could be in range 90% of the time, and still be running too high. I look at my Tiime In Range, but give it value when compared to my A1C, and the numbers of high’s, 180+, and low’s, 70-. My Time in Ranges average in the mid 80%’s. I would like to get them a little higher percentage.

      I put Time in range as extremely important. Since my CGM allows it to be adjusted, I set mine to be 75-150. 180 is just too high.

      TIR is as important, if not more than, A1C. You can can be all over the map, spending more time high and low than in range and still have an excellent A1C. Before cgm, I was running 35% low, 35% high, and only 30% in range (70-180). A1Cs were always high 5s-low 6s.

      I feel that it complements the A1c numbers. I have a friend with great A1c results, but was in range less than half the time. He is on a better path now that he can look at the range and not just the average. Most of us who have the option make changes to the range being measured.
      Libre also has a “daily pattern” view that summarizes the time lines for several days. This makes it easier for me to spot a new trend, which might not have been obvious by scrolling back through lists or readings.

      The benifit ot TIR is you can see daily or 2 day results. I use it to see how I respond to different or new situations. My responses are all over. I document responses so I can fine tune my response. More carbs, less carbs. More activity less activity.

      I never took note of TIR until Tandem introduced the “bolus by phone” feature, which forced me to download the t:connect app, which has the TIR metric on it. However, I find the “range” to be too large to be useful. You could ride at 180 consistently and have “100% TIR”, which is not ideal for me.

        I upload my Tandem X2 with Dexcom integration every month. And I print out the reports. I agree that the range is too broad, so I run reports using the default range (60-180) and then run it again for my personal preference (60-130).

      It’s very important, more than 6 month A1c’s, but other lab results are also considered before making any changes.

      As others have pointed out, A1C is an **average**, which means you can have a great number that obscures how much you’ve been roller-coastering to end up there. TIR, with the stats for time above and time below says a lot more about how you’re actually doing. And you can set those parameter values manually in Dexcom if you want to tighten them up.

      Worth noting that TIR stats only **exist** because of CGM tech. A1C average was all there was in the bad old days, though you could kinda-sorta get an idea if you were finger-sticking 8 times a day. It’s definitely something all T1s–and T2s for that matter–using CGMs should be attentive to it.

      Normal blood glucose for human beings is 83. Standard deviation from that number tells you how consistent your control is. A TIR based on the notion that it is acceptable to get to 180 is hazardous to our health.

      I prefer time in range as a measure of T1D management over A1C because I can look at it daily or over specific time ranges and set better targets for myself. Without it, variability is hard to assess.

      Essential in tandem with other metrics. No one metric alone is enough to manage BG well. It would be nice to set my own goals for time-in-range though. I’d like tighter control but I have Control IQ.

      My A1C has not improved with the TIR available to me. The best way I have found for the last 47 years is by doing a paper chart, with a week’s worth of BG. ‘s on one page. I then see whether the high sugars are consistently right after lunch or right before supper or at night or whatever, and that can determine whether I need to adjust my basal (or, formerly, long acting insulin) or my bolus (or, formerly, short acting insulin). I keep a year’s worth, so I can tell whether the changes are due to the season of the year as well, or whatever. My sugars have gradually gone up with stress for 6 months before the weddings of two of my children, for example. I now know that on wedding day they will plummet precipitously.

      TIR is absolutely essential for T1D management. I also use the STDDEV to determine wide swings in BGs. A1C, for me, is inaccurate as I have wide swings in BG (being brittle T1D and Type A personality). The lows distort the A1C. TIR + StdDev shows a more accurate pictures.
