Not sure if you still have the machines to do this test again but maybe they both would be more accurate if you wipe your fingers with an alcohol wipe?
Hi Dr. Brewer. After reading some articles and also the failure of Theranos company's blood test, I think one import point is that we could not squeeze the blood out before testing since the squeezing might dilute the finger blood by squeezing more cell cytosol than blood and adding too much cell debris and noises, the same reason why Theranos company cannot give out accurate blood test result by single drop finger blood. I did try by my self with my freestyle lite glucometer and found out that a larger amount of blood drop gives a higher reading while a tiny amount of blood from squeezing always reads around 20 less.
I use the Freestyle Precision Neo and have used a Contour Next a few times, but stopped because the Contour Next was reading 20 to 25 points higher than the Freestyle. When I feel that my Blood Sugar is low I will use both meters and the Contour Next will always read about much higher which makes me think that the Freestyle is not accurate because of low readings.
I bought a WalMart glucose meter and compared to my old AccuCheck machine which is pretty accurate; however, insurance dropped Accucheck test strips. The cheap Walmart meters had high variations as much as 30 - 35 points from the Aviva test strips (which are more expensive). Aviva said 90. The wal-mart brand tested 115. Big difference. However, NO glucose meter is 100% accurate and those numbers will change every second even taking it from the same stick. Since the sugars are brittle I tend to trust the more expensive test strips -- you get what you pay for. Since insurance will no longer carry Aviva I switched to Freestyle.
Nice video, I was scanning my sensor before with reader. For the last few months, I have been using Nightrider cgm with my Libre which helps me to monitor glucose readings on phone screen without needing to scan. it's great!
You checked it a few minutes ago and got completely different readings on both meters. Since your blood would not have changed that much in a few minutes, they are both basically worthless. Also, you can get a control solution to check them and then have some idea of what they should be reading.
So i guess you should always use a 25point margin of error.thats very disapointing because its a big diference and can turn a good reading into a bad one and its not as accurate as they lead you to believe
Nice video, I use Libre and Blucon and love them to control my blood glucose values. The alarms are nice and are loud enough to wake me up. You can adjust your BG ranges to whatever you want. The best part of blucon is I can calibrate it for higher accuracy!

Nice video, I diagnosed with T1 and use the FreeStyle Libre sensor with Blucon transmitter, I track blood glucose readings on watch and phone constantly and the phone beeps at night when the glucose is out of range.

I'm ready to throw away my Onetouch meters, they always test 10 to 20mg high against my Freestyle Libre CGM and even verified it with the Neo Precision Test strip which is Hospital grade. The problem is the strips, not the meter. Since the newer strip don't require calibrating - which means all strips are manufactured calibrated at 25. This means that they don't bother to calibrate each batch to simplify the manufacturing process.
I had professional lab work done at Lifelabs yesterday. Also took the opportunity to compare fasting blood glucose readings of 3 glucometers I own, Freestlye Lite, Accu-chek Aviva, and GE100, against Lifelabs fasting blood glucose reading. Immediately after the blood draw at the lab, I tested with the 3 glucometers while sitting in my car. Here are the results. Lifelabs: 99, GE100: 90, Accu-chek Aviva: 83, Freestyle Lite: 77. I was astonished and dismayed, especially with the difference between the Freestyle reading of 77 compared to Lifelabs of 99. I have used Lifelabs for 3 years. Results have been fairly consistent. And, I had checked Freestyle Lite with the control solution provided. What do you think, Dr. Brewer? Thank you.
Thanks Doc, nice review, quick and to the point. I have recently obtained GE100 meter and strips without insurance. $9 for the meter, and $8 for 50 strips. A Bargain and running them side by side. I test several times a day, at least 8, and of course there are variations. Some 5 to 10%. Freestyle strips cost around $1.89 per and around $0.40 per with insurance. Whilst FreeStyle lite is indeed the smallest meter I have owned and I like its ease of use and low blood droplet. I am not happy with the cost of the strips. I think I can get used to the GE100 meter. I can also live with the difference, after all what is important is trend. Non of these at home devices are "accurate", Accuracy is a loaded term. Most meters are +/- 10 to 20% from run to run. Even Freestyle lite.
After my fiasco with the iHealth Align, I tried again to find an acceptable meter with cheaper test strips and picked the GE100. It was developed by General Electric in conjunction with Bionime. The Bionime GS550 was tested in a study against 2 other meters and it turned out to be accurate enough, so based on Bionime's reputation I decided to order the GE100 a few days ago. From what you are saying, the variations seem acceptable. Looking forward to its arrival. Thank you for your comments.
@@lilystonne4108 I conducted a very detailed GR&R test on three devices, GE100, Bayer Contour and Freestyle lite. GE100 (aka Bionime) came on top. I am more than happy to share the spreadsheet. But not quite sure how to. I will find a way. and paste a link here.
Although I am happy to learn that someone else has found the GE100 to be the most accurate in a comparison, I must admit that I am disappointed with the Freestyle Lite. Since I am trying to lower my blood sugar by eating low carb, and the Freestyle Lite has always given the lowest readings when compared to another, I liked it very much. Also since many reputable persons have recommended it, I trusted it the most. Now, I am not so sure. Thank you ds9quark, for replying. Yes, I hope that you can find a way to reveal the results of your experiment.
Thank you for your help as I have not been diagnosed as a diabetic but I am watching what the results are after eating certain foods. My mom was diabetic so I may have the genes in me?
Do not buy the iHealth Align glucose meter. I was looking for a meter that uses cheaper test strips than my Accu-chek Aviva. Although it had mixed reviews on Amazon, the test strips were half the price. I discovered that the readings on the iHealth Align were 10 to 25 points higher than the Accuchek. So the question was, which was more accurate one? Following your recommendation, I bought the Freestyle Lite. The readings were more in line with the Accu-chek. I wanted to use up the iHealth strips, so I continued with it. Just now, I tested post dinner and got a reading of 148, after eating a low carb meal. Using blood from the same prick, I immediately tested with the Freestyle Lite and got a reading of 106. Man! That's a difference of 42 points!!! I packed up the useless iHealth device and threw it into a drawer. How can they get away with selling such a piece of junk! 😡
Thanks so much for sharing that. Yes, we want to see trends. But that level of error makes it very difficult. Thanks for verifying- and again, sharing the results. Please share the videos, too, so others can benefit.
I have both testing meters. When I test with the FreeStyle Lite meter, my glucose test reading is always LOWER than... when I test with the One Touch Ultra meter.

Thanks for sharing that. I think the microdrop, blood spot tests are closer than you might think.
It’s not a Contour, it’s a OneTouch

I think Consumer Reports latest report on glucometers would be the best source of what is the most accurate glucometer...at least its unbiased
You checked it a few minutes ago and got completely different readings on both meters. Since your blood would not have changed that much in a few minutes, they are both basically worthless. Also, you can get a control solution to check them and then have some idea of what they should be reading.
Yes. These are not lab grade. People don't think about that. They tend to think these are far more objective than they are. Thanks.
So i guess you should always use a 25point margin of error.thats very disapointing because its a big diference and can turn a good reading into a bad one and its not as accurate as they lead you to believe

After fasting for 16 hr check your blood sugar with different brands.

Hi Doc. Which is better and accurate freestyle freedom lite or freestyle lite? Thanks for answering it.
is there a difference?
Doctor what you are using is one touch ultra 2. It is not contour
Thank you for your help as I have not been diagnosed as a diabetic but I am watching what the results are after eating certain foods. My mom was diabetic so I may have the genes in me?

Most of the time people want CHEAP... Cheap is not necessarily the best choice when it comes to important health evaluations such as glucose levels.
I have both testing meters.
When I test with the FreeStyle Lite meter, my glucose test reading is always LOWER than... when I test with the One Touch Ultra meter.
Lady Day Do the lab work same time then see the actual results
It is lower than one touch but it may be the correct reading
If eat two hours before and had 100. Blood count
Please if I just eat a two hours before takeing my blood sugar and it was 100 was I suppose to a lot longer after eating
sir I i want to buy a precise glucometre for my mother. which one should I buy contour plus one or freestyle lite?does both have accurate results?
Contour is not good.
@@PrevMedHealth sir but google search says that it's accuracy is 100 percent.and also it is said that it is on 1st number.what do you say ?
nice i used freestyle i can't set it up for my life
Walmart ReliOn is worthless reads up to 30% higher than my back up GE100 meter which is now 2 years old with a new battery. They should be banned!
I don’t understand the quality systems for these things.
