The FreeStyle series of blood glucose meters from Abbott are essentially the same meter with a few distinct differences. The FreeStyle Freedom Lite® is larger and the Freedom Lite® has a few lights built in. If you push the light button on the FreeStyle Lite®, a backlight comes on to backlight the display. If you have a test strip inserted, a light shines toward the test strip end so you can see your testing site better. Those are the major differences between the two.
Lets talk about what they have in common. They both use the same FreeStyle Lite® Test Strip. Both meters provide a 7, 14 and 30 day blood glucose average. They both have a serial USB data port to export data to the CoPilot Health Management Desktop Software. They are both easy to use but they are slippery at times. I have used the FreeStyle Freedom Lite® for about a year. I have nothing bad to say except the darn thing has slipped out of my hand many times. Now people drop things, that is a fact of life, but shouldn't a device which is more than likely going to have more elderly people using than not have some rubber sides. Something to allow the user to get a good grip. I am not elderly, but during a low blood sugar episode last year I could not keep the meter in my hand. OK, At that point I guess I did not need a meter to tell me to drink some orange juice, but still. I think both meters are very good for Alternate Site Testing, in fact I think they are the best glucose meters for Alternate Site Testing.
The FreeStyle Lite® test strips need only a .3 micro liter drop of blood. In over 300 test I had zero errors. That is very impressive. If you do not get a large enough sample, you can re-prick and get more blood within 60 seconds of the first attempt. I think this is the only test strip with that feature. If you are someone who hates wasting strips these meters are for you. The Clarke Error Grid show the accuracy of the FreeStyle test strips when compared to a lab glucose test.
A recent hematocrit interference study to test the ability of blood glucose meters to correct for a range of Hematocrit levels concluded that the FreeStyle Freedom Lite failed to to accurately meet their standards.

A nerdy glucose meter must allow for "alternate testing locations". This means no finger pricks. Nerds need their finger tips pain free to keyboard and swipe.
A nerdy meter must allow for data transfer to a computer or website for in-depth analysis and review. How a meter connects to a computer is also important.
The last part is optional based on the prior features, but it is really nice when a meter can record data other than date and time of a glucose reading.
A DIABETIC woman from Northampton has been presented with a medal to mark 70 years of coping with the condition.
When Grace Jarnell was diagnosed with Type 1 diabetes while aged 12 in 1942, treatment was so basic she had to heat her own samples at home over a Bunsen burner to see if she needed insulin.
Now, more than 100,000 injections later, she has defied the worst fears of doctors and been awarded a medal in recognition of seven decades of coping with the condition.
Drinking two glasses of water before each meal may help people lose weight, a new study has found. Obese dieters who drank two glasses before breakfast, lunch, and dinner lost five pounds more than their dieting peers over the course of three months. Experts say it could be that the water helps fill people up more quickly, thus ensuring they eat less.
