Generic vs Brand Name Test Strips: Are They Really as Accurate?

If you've ever stood in the pharmacy aisle staring at two boxes of test strips — one a familiar brand name and one a much cheaper generic — you've probably wondered: does it really matter which one I choose? The good news is that you're not alone, and this is one of the most common questions people with diabetes ask. Let's break it down in plain language so you can make a confident, informed decision for your health.

What Are Generic Test Strips, Exactly?

Generic test strips are blood glucose strips made by manufacturers other than the big brand names like OneTouch or Accu-Chek. They're designed to work with either their own branded meters or, in some cases, compatible meters from other companies. Think of them like store-brand cereal — same basic function, different label and price tag.

• Made by third-party manufacturers, not the original brand

• Often significantly lower in cost per strip

• Must meet FDA clearance standards to be sold in the US

• Designed for use with specific compatible meters

• Available through pharmacies, online retailers, and suppliers like MDS Diabetes

The Big Question: How Is Generic Brand Name Test Strip Accuracy Measured?

The FDA requires all blood glucose test strips — generic or brand name — to meet the same accuracy standards under ISO 15197:2013. This means results must fall within 15% of a lab reference value at least 95% of the time. So on paper, generics are held to the same bar as the brands you already know and trust.

• FDA clearance is required before any strip can be sold legally

• ISO 15197:2013 is the global accuracy standard for glucose strips

• Both generic and brand name strips must pass the same testing

• Accuracy can also be affected by storage conditions and technique

• Always check that your strips are FDA-cleared, regardless of brand

Where Generic Strips Can Shine

For many people, generic test strips perform beautifully in everyday use — especially when you're testing multiple times a day and costs add up fast. Choosing a quality generic can mean you test more consistently without worrying about the expense, which is actually great for your overall diabetes management.

• Lower cost encourages more frequent testing

• Wide availability online and through suppliers

• Some generics are made in the same facilities as name brands

• Great option for those without insurance coverage

• MDS Diabetes carries a carefully selected range of affordable test strips

When Brand Name Strips Might Be the Better Fit

There are situations where sticking with a brand name strip makes practical sense, especially if your doctor or diabetes educator has calibrated your management plan around a specific meter and strip combination. Insurance plans may also only cover certain brands, so it's worth checking your benefits before making a switch.

• Your insurance may only reimburse specific brand name strips

• Some meters are only compatible with their own brand's strips

• Certain clinical conditions may require tighter accuracy margins

• Your healthcare provider may have a strong preference

• Continuity matters — switching strips mid-routine can cause confusion

Tips for Getting the Most Accurate Results — No Matter Which Strip You Use

Here's a little secret: the brand on the box matters less than how you use and store your strips. Even the most expensive test strip can give you a bad reading if it's expired, stored in a hot car, or used with wet fingers. Good habits are your best accuracy tool.

• Always check the expiration date before testing

• Store strips at room temperature, away from humidity and heat

• Wash and dry your hands thoroughly before each test

• Use the correct amount of blood — not too little, not too much

• Keep the vial tightly closed after removing a strip

How to Choose the Right Test Strips for You

The best test strip is the one you'll actually use consistently and that fits your budget, your meter, and your lifestyle. Start by confirming which meter you have, then look for strips that are FDA-cleared and compatible. When in doubt, your pharmacist or diabetes care team can help point you in the right direction.
