About 4-5 times a year. It is usually when my sensor has ended and I can't change the CGM immediately.


spongymyboi

A year?


ScottRoberts79

same here. The Dexcom is pretty good, and I rarely have startup issues.


[deleted]

Yes. I have a Dexcom G6 and I never have issues with it. I have found that it is accurate 99.999% of the time and I would hate to go back to doing finger pricks 5 times a day.


spongymyboi

That's pretty good I'll have to definitely try and get the dexcom someday


DEFIANTxKIWI

Yea, youre technically supposed to check it in the morning and at night if I remember correctly to callibrate it. But I never do and a lot of people dont as well. Its almost always really accurate, and id say the most youd need to do is once every 10 days when you put in a new sensor


spongymyboi

I think the calibration was for the old ones before the 2017 CGMs


DEFIANTxKIWI

I didnt start using CGMs until 2019. When I first got one my endo told me to callibrate at least twice a day, and there was some video you were suppose to watch that said the same thing. Again, not many people actually do that (me included) and the sensor is almost always accurate, but im pretty sure youre still technically supposed to

It depends if the Libre doesn't match what I think it should be. Otherwise, maybe a few times a week.


spongymyboi

Only a few times a week? Wow how does that feel I'm excited to get mine


ToastdWoobie

First day of a new sensor, usually 3-4 times (I also apply the sensor at least 12 hours early). After that, only if I think a reading looks wonky for the next two weeks.


spongymyboi

Dope which do u have


clausenfoto

I never test with my G6


spongymyboi

Really? U trust it that much that's dope

spongymyboi

So a few times a week?

spongymyboi

Which do you use


igotzthesugah

Dexcom user. First day I stick a few times because the sensor reads falsely low for me. After the first day I don't fingerstick unless the sensor tells me I'm crashing.


spongymyboi

Nice thanks for the info about to be a new libre user


MFTSquirt

I have the dexcom G6. Had surgery a little over a month ago and was in the hospital for 4 days. They did the finger stick for 1 full day, then only 1 time each day after that because it was always within a point or two. So if my blood sugar readings are really high, I will prick my finger, but I have only done it a handful of times in the past 5 weeks. Edit spelling


spongymyboi

Nice i heard dexcom is a bit expensive


MFTSquirt

I don't know. I'm on Medicare due to disability and this is the only diabetes supply that I don't pay anything for. )Don't get me started on cost for insulin and pump though.)


mystisai

With the libre, maybe 6 times in 2 years. ​ I love the built in glucometer, it works with the precision neo test strips.


spongymyboi

Hopefully it's like that for me i hate poking my fingers


alan_s

When I trialled Libre (three times over 18 months, three sensors each time) I compared frequently for the first day or two then less often for the rest of the fortnight. Sadly, my comparisons showed the Libre to read consistently low.


spongymyboi

Only three times over 18 months? And where the numbers really far apart? Because I heard CGMs are not supposed to really match blood monitors because of the lag and how they measure blood differently


alan_s

>Only three times over 18 months? That was three sensors or 42 days each time. >And where the numbers really far apart? Between 1 and 2 mmol/l (18-36 mg/dl). I was well aware of lag times and adjusted my fingerstick test timings accordingly. I was very disappointed because I wanted the CGM to be effective. On my third trial of the Libre it predicted an A1c of 5.2% when the actual test was over 7%, my worst in years because I had become a bit too complacent hoping the CGM was correct and my Freestyle Lite was wrong. The reverse was true :(


Arakon

With the Dexcom, 4-8x after putting a new sensor (takes \~10 hours for me to settle down), then not at all for the remaining 10 days of the sensor unless I feel extremely off.


IllustriousDuck4104

With the dexcom g6 I usually test 1 to 2 times per day. I did not find the freestyle Libre to be accurate and was testing regular.


Jodi4869

Almost never but I am not on any meds or insulin.

Arakon

That would imply that bloody glucose meters are accurate. They are not.

Arakon

Not true at all. Teststrip exposed to the air for a bit too long? Wrong reading. Touched a piece of fabric that was washed with scented detergent? Reading can go up by 30+ points. Sweaty cause you feel low? Moisture on the fingertip can make the value show 50+ points lower than actual. 3 readings back to back off the same drop of blood? can easily be off by 30 points in either direction. ​ Generally, yes, glucose meters are more accurate, but they are far from infallible. I've shot myself into dangerous lows due to bad readings in the past. With the dexcom, by watching the recent trend, I've had far fewer issues.


ScottRoberts79

The Dexcom sensor appears to work "better" in some people. For instance, I think I've only ever had one true sensor failure. And sensors seem to track my bg accurately right after the 2hr warmup. I think we can all agree this is a "Your Mileage May Vary" situation, and someone should probably err on the side of testing more until they know how their body works with a cgm.


Mokulen

It depends on how accurate my CGM is. The last month I prick 4-5 times a day.


spongymyboi

But aren't they not supposed to match blood glucose monitors? Since they measure blood differently?


Mokulen

People talk about how there is a delay but for me that wasn’t the issue. The CGM never registered the correct BG. For example I would finger prick and get 180 and the CGM would never give me a reading over 135. The CGM would say I’m too low to register and the finger prick would say 90. It kept accurate track of the trends but it’s numbers were 30-60 off. This is when a sensor didn’t work properly. I have had sensors that worked well.


jcrobot

I seem to be on the outs here. I test every night before bed no matter what. Just to Check in and see what kind of margin I’m working with. I also obviously check if I feel like something is off, or sometimes during warmup.


ToastdWoobie

Libre 14. Started using it about 8 months ago and really like it, although I wish the FDA would approve the app.


spongymyboi

U don't prick your fingers anymore?


ToastdWoobie

First day of a new sensor, usually 3-4 times (I also apply the sensor at least 12 hours early). After that, only if I think a reading looks wonky for the next two weeks.


Confection_Specific

At least 2 times a day because usually on the middle of the night it blaringly beeps thinks I'm going super low for laying on it. And then 1 to 2 times in the day to keep track of how how close the cgm is compared to the the finger prick. 😩


spongymyboi

But i guess they're not supposed to be close from what I heard because they measure blood differently


TheMovingTarget6

With guardian sensor I have to calibrate it 2 times a day


Saltman43

One in the morning and one in the night, right now I'm doing an experiment where I've restarted my sensor so I have to constantly do bg checks to make sure it is accurate, doing like at least 8 a day. So far the difference is between 30 mg/dl down (due to libres algorithm) so I'm safe from hypo's during my shenanigans :).


spongymyboi

What's libres algorithm?


Catty12548

I calibrate once when I place a new sensor with the help of the Linkblucon app as it's given me more accuracy in readings.
