How Long Are Test Strips Good After You Open The Bottle?
Posted: March, 2012 If you landed on this page, I suggest you go to the beginning to see what affects the accuracy of test strips. In an effort to know how long after you open a test strip bottle they can be used, I called 6 major manufacturers of Glucose Meters. I asked each of them how long their strips are good, after the bottle is first opened. Assuming your are closing the bottle after each use and storing the bottle per the manufacturers directions, here are the results. All the customer service representatives were very helpful and I had no problem getting my questions answered1. OneTouch® - Good for 6 months after you first open the bottle or until the expiration date, which ever comes first. Accu-Chek® - Good to the expiration date on the bottle. The strips have an 18 month life span and it is estimated that once they arrive at the retailer they have 14 to 16 months left. FreeStyle® - Good until the expiration date on the bottle. Bayer® - Good until the expiration date on the bottle. Agamatrix® - Good for 90 days (three months) after you first open the bottle or until the expiration date, which ever comes first. Nipro Diagnostics®- Good for 120 days (4 months) after you first open the bottle or until the expiration date, which ever comes first. I find it interesting that Agamatrix®, manufacture of the WaveSense™ technology only last 90 days while the Accu-Chek® last up to 16 months. I find it somewhat odd that Abbott and Bayer do not establish a shorter expiration date based on the first opening the of the bottle while all the other strip manufactures do establish a time restriction. I am told that both Agamatrix® and OneTouch® test strips are available in a 25 count bottle. I like that idea. If I learn of any others who provide a less than 50 count Continue reading >>

Do Test Strips & Diabetic Supplies Really Expire?
As I mentioned, I’ve been searching for an article on pharmaceutical expiration dates for a week. But finding an objective piece in a sea of editorials (including my own posts on the subject) was very frustrating. This morning, I stumbled onto an article titled Do Medications Really Expire? It’s from a 2003 Psycho-pharmacology column in Medscape (Thomas A. M. Kramer, MD). The article’s findings are worth reading… I just want to clarify one point. Insulin is one of the exceptions to the rule. Do not use expired insulin! Okay, here’s another excerpt followed by a link to the whole story: “Manufacturers put expiration dates on for marketing, rather than scientific, reasons,” said Mr. Flaherty, a pharmacist at the FDA until his retirement in 1999. “It’s not profitable for them to have products on a shelf for 10 years. They want turnover.” That they do. Here’s a clip and the rest of the story: “One of the largest studies ever conducted that supports the above points about ‘expired drug’ labeling was done by the US military 15 years ago, according to a feature story in the Wall Street Journal (March 29, 2000), reported by Laurie P. Cohen. The military was sitting on a $1 billion stockpile of drugs and facing the daunting process of destroying and replacing its supply every 2 to 3 years, so it began a testing program to see if it could extend the life of its inventory. The testing, conducted by the US Food and Drug Administration (FDA), ultimately covered more than 100 drugs, prescription and over-the-counter. The results showed that about 90% of them were safe and effective as far as 15 years past their original expiration date.” Continue reading >>
Can People With Diabetes Use Expired Blood Glucose Test Strips?
There has long been the debate of whether people with diabetes can use expired test strips. So, can you? Rather than simply answering yes or no, it is important to first understand what exactly a test strip is, and why the argument over expiration first came to pass. The key aspect is enzymes. Enzymes, which are proteins made by cells in all living organisms, coat the end of the strip, which is made of plastic. These enzymes are either glucose oxidase or glucose dehydrogenase. The enzyme reacts with the glucose in a person’s blood and converts it into an electrical current. Upon the electricity being sent through the strip, the glucose concentration is presented by the blood glucose meter.  Here’s the thing, though. Enzymes break down over time. The activity of enzymes can decrease following exposure to humidity or extreme temperatures. This can alter the accuracy of glucose readings long before a scheduled expiration date. Subsequently, errors can begin to appear with rogue readings of either a high or low nature. Because the enzymes break down, manufacturers therefore place an expiration date on the strips. This is a necessity for manufacturers. Even if they are confident the strips will display accurate readings for x amount of time, one faulty test strip could lead to a diabetic patient making a management decision that could cost them their lives. The dates may differ depending on how the strips are made. The use of different enzymes can provide greater accuracy with a shorter life or vice versa. Some companies may go for the cheapest alternatives. The accuracy of expiration dates No-one is expected to believe that an expiration date scheduled for a Wednesday will enable to you test accurately on Tuesday, and then not again the day after. However, anecdotal e Continue reading >>

In order to understand whether or not you should be using an expired test strip, it can be useful to understand how they work. The basic explanation is this — a liquid-attracting layer moves your blood into the little window on the strip, which is known as the “chemistry strip.” This strip is made up of an enzyme and what’s known as a mediator. The enzyme attaches itself to the glucose in your blood and pulls off sugar electrons. The mediator then passes the enzyme through the circuit to get you your reading. The enzyme is “living,” which is how a diabetic test strip is able to expire in the first place. Eventually, the enzyme will “die,” or break down. And then it will not be able to attach to the glucose in your blood or pull off the sugar electrons. But when exactly do Continue reading >>
