Colloquially, many know GTIN as a barcode, but technically, GTIN is the number found beneath the barcode symbol itself, and can therefore also be used for other technologies such as 2D barcodes and RFID tags.
With the GS1 Clinical Trial Application Standard, you get a global and harmonised way of identifying investigational products in clinical trials.
This makes the supply chain more efficient and everyday processes simpler for both manufacturers and end users.
Correct identification of investigational products is crucial in clinical trials—both for patient safety and for the smooth handling of the products.
The GS1 Clinical Trial Application Standard er en global GS1-standard, der sikrer korrekt identifikation og mærkning med scanbare stregkoder af forsøgsprodukter. Standarden er udviklet med repræsentanter fra virksomheder og kliniske forsøgssteder med fokus på at gøre arbejdet for sponsorer og investigatorer nemmere.
The standard also includes a necessary guideline on how to efficiently exchange electronic data (EDI) about the investigational product. EDI ensures that your orders are processed automatically—saving time and resources while avoiding data entry errors.

Standards are already widely used for commercially marketed products. All products entering the supply chain are labelled with a 2D barcode and the product’s globally unique identification number. When all manufacturers follow the same standard, processes become consistent, easier to manage, and simpler for end users to handle.
Harmonising and applying the GS1 standard to clinical trial products can bring many benefits. It is a global standard that can be used worldwide.
Here you can see a clinical trial product labelled with a GS1-datamatrix.

Identification of investigational products is important, and GS1 has developed a global standard in collaboration with industry and clinicians that can be used to identify clinical trial products.
Watch this short video on the identification of investigational products, which explains how the standard was developed and the benefits it provides.
Manual registrations are time-consuming and increase the risk of errors.
With electronic data interchange (EDI), you achieve automation, allowing orders to be processed automatically and eliminating the need for manual data entry.
See for yourself how electronic data exchange in clinical trials can create value for you in this short video.
