This control solution is to be used with your glucose meter to make sure it is accurate. The way to do this is to use a drop of the control just like you'd use a droplet of your blood, and compare the meter reading to the value the solution actually is. BUT the solution does not tell you what the value is. It's supposed to be printed on the label, it's not. That info is nowhere to find on the internet. Buy a control solution that you know what your meter should read for, or it's a complete loss of time and money. Read more

I'm diabetic and use a lot of test strips. About once a week, I open a new container of 50, and need to test them. This solution works fine but went out of date in about 6 months, much faster than it was used up.Big picture - I'm disappointed Bayer makes me pay for solution and then use up 2% of my test strips (not cheap!) to test whether they did their job right, then sells it with a near-term expiration date.Bayer should at least put the expiration date in the ads.

I tested this solution on (3) different meters (different brands) and all three came out incorrect. On the product bottle it says “control level 2” and according to my test strips the range should be mid-high 200’s to 300’s. I put the solution on and on all three monitors (all different brands of test strips) the metered amount came up as low 100’s to below 100. That’s more of a level 1 solution. The product expiration is 2021 so it’s not expired. Not sure what this stuff is they are selling. Good luck!!! Read more

Before you buy, make sure that your monitor needs coding. My monitor is no coding, and returns are not accepted. Waste of money. Read more

These items expire in August!!! It should have been at least a year before expiring!!! What a rip off... and of course there is no return on these items! Read more

I ordered this July 8, 2021. Expires in 7 months. I wouldn’t mind paying twice as much. If it had the one year expiration date that is supposed to have. This things tend to go bad a month or two before the expiration date on the bottle. So this one is probably going to be good for another 5 months. Read more

I am giving this only 2 stars because I received the product in March and it expires in August. I will never be able to use two bottles in 4 months. What a waste. Read more

A necessary item if you are a diabetic and have to measure your blood glucose level. This is the "calibrating" fluid. Put it on a test strip and you should get a standard reading. If not, your meter is out of whack. Please NOTE: This is for the Bayer products that use the Contour NEXT products. NOT simply Contour. The Contour is an earlier generation product and the two are incompatible. I highly recommend this control solution. Read more
