SD CodeFree Glucose Monitor Kit - Blood Sugar Monitor with 500 Memory, Test Strips & Lancets - Diabetes Testing Kit for Blood Sugar Test - mmol/L UK Standard

Despite the negative reviews about this product I am very pleased and bought another one for my mother, because the test strip for this meter are the cheapest on the market . First I want to commend Home Health (UK) Ltd as a good and correct seller. They were very fast and accurate. In terms of electronics engineer, I can say that the SD Codefree Blood Glucose Monitor is a quality and designed to be easy to use. I'm sure those users who define the product as inaccurate, do not know how to measure properly. This is a simple electrical resistance meter. Blood glucose changes the resistance of the active surface of the test strip. From experience, I found that, if you follow some simple rules, the results will be accurate and repeatable, and they are:1. Use the test strips before the expiration date2. Keep the test strips properly as described in the instructions3. Hands should be washed and dried before measuring4.Do not touch with fingers contact and active surface of the test strip when you put it to the meter. Hold the test strip in the middle.5.You don't need of big blood drop, because excess amount of blood additionally changes the resistance of the test strip and the readings are high.6.Do not dip the test strip in the blood drop. This is a big mistake.The window of the test strip by capillary method draws the blood and should be fully.Immediately after the window of the test strip is has been blood filled, the test strip must be removed from the blood drop. The best case is when the droplet is just as much as is necessary to fill the window, but you need of experience to be achieved that . If the window of the test strip is not full up, the readings will be lower .Despite of all ,you need to know that all blood glucose meters have max error 20%. When the real blood glucose is low ,the error is small . In the most cases, the measurements are accurate, if the rules are have been followed. If you have any doubts you may calculate within what limits is your real blood sugar by this way: If we have measured 5mmol / l and we have a doubt that it is very low then the maximum possible value is 5x1, 2 = 6 mmol / l. If you have any doubts that is very high then the minimum possible value is 5/1, 2 = 4,17 mmol / l. The real value is in the range [4.17 to 6]mmol/l. If you want to have max accurate you may to average at least 3 measurements. I hope I was helpful.

This glucose meter is really good value, particularly if you are buying your own test strips, as they are very much less expensive than for other meters, a third the price of some. Sadly some medical practices now restrict test strips, particularly for type II patients not on insulin.This may not be the most accurate meter, though it seems pretty good, but if you need to regularly check your blood glucose, perhaps several times a day, particularly if you are paying for the strips, this is certainly good enough to keep track of things.I was having great difficulty with my glucose levels until I read, "Blood Sugar 101: What They Don't Tell You About Diabetes". So I realised I needed to go onto a lower carbohydrate diet and check my glucose just before and about 2hours after each meal, to ensure it was under control, preferably no more than 8 mmol/l. Hence I am using a lot more test strips than I am allowed, at least 6 a day, but it is a great help and with this meter and I can now afford the test strips. The result has been very successful in improving my glucose levels and putting off the need for insulin.I have found the lancing device that comes with this meter is perfectly adequate and about the same as any other, although I use other lancets that I already have, so I don't know why some have a problem with this one.If you want the USB connecting lead to your computer and the program to save, analyse and display your readings, this is not yet available trough Amazon, but can be obtained directly from Home Health (UK) Ltd, for about £23, who also sell the meter on Amazon. Just Google Home Health (UK) Ltd, click on Glucose Monitor and scroll down to "SD Codefree Diabetes Management Software Cable". From there you can order the cable and download the program to your computer.If you are having difficulty reading the small User Guide, then from Home Health, or directly from SD Biosensors, you can download a PDF copy of the guide and read it enlarged on the screen, or print an enlarged copy of the pages you need. There will similarly be a PDF copy of a handbook for the computer program, though that is currently being updated and should also soon be available through Home Health, or SD Biosensors.I don't yet have the cable and have not yet tried out the program, but will update on that later. I initially had a problem loading the program and obtaining the cable, so contacted SD Biosensors in Korea, who sorted out the problems for me.In the mean time this meter has been a great help in controlling my diabetes.
