I was hesitant to score TMAs for the BASIS project digitally, I usually score glass slides with a PhD student recording the results. Using Slide Score was much faster and easier. I appreciated the option to see my answers on top of the cores to quickly review the slide before moving to the next one.
This is the way TMAs should be scored.

We have used Slide Score to collaboratively stratify patients in a clinical trial. It has worked flawlessly so far, the 4 of us have always been able to reach a consensus within 24 hours. Support was helpful and fast - when one of us needed a tool to measure area it was added within 2 days. And Slide Score works great on my iPad!

Slide Score is an intuitive user-friendly digital pathology tool for translational research purposes.
We have used the Slide Score API to automatically upload scanned slides from our (in-house developed) lab management tool, the ‘Application and Request Tool’.
Without any trouble we can add slides to the relevant studies, give researches or pathologists the appropriate access and receive the scoring results. They are automatically uploaded to our database and if applicable to the datawarehouse.
Slide Score supports the complete organization of our digital slide logistics like sharing, scoring, TMA grid manipulation etc resulting in improved management of the translational research digital pathology process.
We fully recommend the use of Slide Score in daily digital pathology setting.
