The Client

CellNass is an innovative, national archive management service for hospitals and laboratories from CellPath Ltd.  Originally intended for archiving cellular pathology blocks and slides, it has expanded to cover multiple materials, such as blood spot cards, transfusion records, documents and more. CellNass now provides a complete archive management solution, ideal for hospitals and laboratories with limited or expensive-to-run onsite storage space.

The Project

We were approached by CellPath to design and build comprehensive archiving, tracking and invoicing software for the material held on site at their climate-controlled facility. Rapid expansion of the company had caused them to outgrow the system they were using at the time, and they recognised that a bespoke piece of software would simplify their workflow, bringing greater control over the archive, easier management and complete trace-ability of archived material.

Aptly named ‘CellTrak’ the software we created provides CellNass with a complete packing and tracking solution, integrating bar code scanners, printers and mobile devices into the warehouse workflow.


Items can be located at any stage of the archiving process - from hospital pickup, through to packing and storing in the warehouse, to recalls from hospitals and disposal every sample is tracked. Archives are grouped by year, followed by their unique packing box reference allowing access to all items listed at that location.

Individual hospitals have been given their own web front-end, allowing them to search for cellular samples, and request those samples to be returned to them. These requests were sent directly to the warehouse management team, who receive detailed location instructions on mobile devices. A web interface enables hospitals to access the tools they need to get a better sight of the material they have archived at CellNass, as well as providing them with the ability to order sample retrievals and disposals.

Each customer is given full administrative control of their own online archive database, with the super user being able to control access to any number of colleagues. Each CellTrak customer also has access to their personal ‘Duty of Care’ section, where they can easily access all relevant documents for their archive. For example, if a customer is being audited, they can quickly obtain the necessary documentation to provide full evidence that their materials are being stored in a safe and secure environment, and that it can be quickly located and recalled at any time.


CellNass management staff are also given a complete overview of the business process, with user activity, stock levels, packing rate and efficiency data in real time.

The number of palettes filled by each packer can even be monitored, with the bar code system greatly improving the efficiency of the packing staff. Over time, we developed increasingly sophisticated control over the palettes and their contents, with recalls, part-recalls and repatriated material all managed within the software, enabling CellNass to make sure that every box in the archive is full to capacity. 

We also created an invoicing system, which tracks the volume of a customers archive, calculates the costs for each hospital, and creates appropriate invoices. This simplified the administration of the billing process significantly.

The results

The Result

Packing efficiency improved by over 50% after just a month of using the new system and we continue to work with CellNass to create on-going enhancement and new features on a daily basis.

The company has grown significantly since we first started working with them. From a single warehouse, they now have three facilities full to capacity, with a fourth currently under construction - every item is archived and tracked using the CellTrak system; an achievement that would have been impossible without our uniquely bespoke software - the only software of its kind in the world specialising in biological samples.
