Blood Glucose Meter

Review: FreeStyle Insulinx Blood Glucose Meter

September 17, 2018 by Frank 2 Comments

This week, I’m on a mission to deplete my remaining supply of FreeStyle Lite test strips. My calculations tell me that they should be depleted by early Thursday. The one piece of motivation that’s getting me through these final days is the mental promise of a new FreeStyle Libre sensor at the end of it. As part of this final hurrah, I thought I’d take the opportunity to celebrate the ‘life’ of my FreeStyle Insulinx meter over the past two and a half years.

I was first given an Insulinx back in 2015 after I had reconnected with my diabetes educator to discuss insulin pumping. This was a meter with a built in bolus calculator that would help me to become familiar with counting carbohydrates, which is what I’d eventually have to do on an insulin pump.

I had been using the same blood glucose meter since the day I was diagnosed. I didn’t know too much about diabetes back then, or some of the more ‘modern’ options that were on the market. Or the fact that ‘free’ meters were so easy to come across, because companies actually make money from the test strips!

The Insulinx was my first ‘modern’ glucose meter. I loved the test strips that were conveniently stored in capped vials, rather than being wrapped in foil. The USB cable, which meant that I was able to upload the data to my computer for review. There was a backlight for testing in the dark. It also used a much smaller sample of blood, and gave you an additional 60 seconds to apply more blood. No more annoying strip fill errors!

As much as I welcomed these modern features, I didn’t really make much use of the bolus calculator function. Mostly because I wasn’t motivated to count carbs and log insulin doses at the time.

Fast forward to today where I’ve tried many more meters and am generally more switched on to what my blood glucose levels are doing, the FreeStyle Insulinx simply does not meet my needs anymore.

The ‘Lite’ test strips may require a smaller sample of blood (0.3uL), however I feel that it’s easier for any sweat or moisture on my fingers to affect the blood glucose reading. I’ve been trying to combat this by extracting a larger drop of blood from my finger and making more of an effort to wash my hands prior to testing. I also don’t like not being able to physically ‘see’ the blood going onto the strip like other meters do.

The bolus calculator on the Insulinx isn’t as comprehensive as the one you might find on a pump or smartphone apps such as RapidCalc. Little things like being able to adjust carb ratios while I’m on my feet at work are a big deal for me. During pump breaks and even while using the YpsoPump, I haven’t even considered the bolus calculator that’s contained inside my Insulinx.

All of these gripes aside, I simply haven’t found the results to be as consistent or as trustworthy as my AccuChek Guide. Just last week I had something like a 12.7, a 10.1 and then an 11.6 in a row with clean fingers. Alternatively my AccuChek Guide has chalked up impressive consistency, even when throwing some grubby work fingers into the mix!

Due to its bolus calculating capabilities, the FreeStyle Insulinx is only available from a healthcare professional. If you’re using a FreeStyle Libre, the same bolus calculator is also built into the reader. Just make sure to ask for the code to unlock the bolus calculator.

I’m mindful that I’m a huge adopter of diabetes technology. Perhaps that’s why I’ve gravitated towards wireless systems such as Contour Next One or AccuChek Guide that will sync readings to my iPhone via Bluetooth for instant review.

For people who do want something simple and may not have the latest whiz-bang smartphone, this could be the perfect option for you.

Review: AccuChek Guide Blood Glucose Meter

May 21, 2018 by Frank 1 Comment

The AccuChek Guide has by far become my new favourite blood glucose meter in recent months.

I first received this meter from my friend Tammy of Diabetes: Forever and Always, before also picking up another one from the trade hall at the ADS-ADEA conference last year. There was, of course, no expectation that I would write or even use the meter itself.

The Guide has been around for a fair while, with it’s first claim to fame being the “spill proof” capped test strip vials.

Strips can also be easily accessed by simply sliding them out of their place, without having to stick your fingers in there and fumble around for one.

While this meter does use a slightly larger blood sample (0.6uL) compared to my FreeStyle Insulinx (0.3uL) and OneTouch Verio IQ (0.4uL), the accuracy more than makes up for it. Past meters have shown big variances from two consecutive readings, aren’t consistent with other meters, or the readings simply don’t match up with my feelings,. Even on grubby working hands, I have found the Guide’s accuracy to be the most consistent and superior.

I also like that I can see the blood go onto the strip, compared to my previous FreeStyle Lite strips which had me guessing whether it was blood or sweat had gone onto the strips.

My biggest gripe, as with other meters, is the strip fill errors. If I don’t get enough blood on the test strip on the first go, which often happens when I’m quickly trying to check during a red light on my way home, I have no choice but to start over with a fresh strip. Alternatively, both my Optium Xceed (does that meter still exist?) and the FreeStyle Insulinx gave me an additional 60 seconds to apply more blood.

One thing that disappoints me most is that every meter in the AccuChek family uses a different line of test strips. In comparison, the FreeStyle family only has two kinds of strips (to my knowledge). This definitely limits my enthusiasm to trial other meters, and does prove inconvenient when trying to stockpile test strips for spare or travel meters.

The guide comes with AccuChek’s FastClix lancing device, which is pretty damn amazing. Each cartridge change contains six lancets, meaning that I can change my lancet six times by simply sliding the little white knob. Unfortunately, this still does not motivate me to change my lancet any more often! There are also 11 depth settings, making the finger pricking experience pretty comfortable.

By far, my favourite feature of this meter is its Bluetooth connectivity to the AccuChek Connect smartphone app. Every time I check my blood sugar, the reading is wirelessly transferred to the app on my smartphone. The app makes it so convenient for me to review my blood glucose data, without the hassle of having to force myself to sit and upload each meter to my computer with its corresponding USB cable.

When you test your blood sugar as often as I do, you’ll get a nice graph of patterns and time in range, which has been really helpful to me while I’ve been adjusting to my pump break.

The app also has a built in bolus calculator that can be accessed with a single use code from a healthcare professional, however this feature has been recalled in Australia for some time. I’m currently using RapidCalc for bolus calculations on my iPhone while I’m on my pump break, but I would love to integrate my insulin dosing into the Connect app as well.

The biggest tradeoff to the additional features is a faster drain on the meter’s standard coin cell battery. I might get 2 months of battery life from checking my blood sugar 10 times per day on my main meter, alternating between a spare and a FreeStyle Libre as well.

The AccuChek Guide is an amazing, amazing meter that has all the bells and whistles for 21st century diabetes management. It definitely helps keep me feeling excited and motivated in managing my diabetes.

Bells and whistles aside, however, the biggest sell for me is that it’s a meter that I can trust.

It’s definitely worth asking your diabetes educator for one on your next visit.
