AI-assisted screening tool that reduces the time, effort, and cost of gram analyses.
Bacteriology Gram Analysis
Our Bacteriology gram analysis solution classifies and counts the following objects (for a full list see below):
Challenges & solutions
Direct microscopic examination of gram-stained slides has several disadvantages, including the cost and time it takes to perform the analysis via microscope, technician fatigue, distraction, and operator bias.
With our bacteriology gram analysis solution, labs can reduce the time and effort it takes to perform gram analyses and obtain greater inter- and intra-operator consistency and accuracy, using a more ergonomic computer monitor.
How it works
Slides are prepared using a standard smear technique, then treated with a gram stain (safranin or fuchsin are both acceptable) and coverslipped for scanning.
Technicians load slides into the chosen scanner. Slides are then scanned and the resulting images are automatically uploaded to the Techcyte platform for Ai analysis.
We accept any good-quality 80x image from a compatible scanner (for a list of compatible scanners, see below). Scanning takes around 1.5 minutes.
Our AI algorithm uses a convolutional neural network to identify differentiating features and determine which combinations indicate a certain bacteria or other diagnostically significant objects. It then places them into the most likely classification for technologist review.
This algorithm is deterministic, making the same classification every time it is shown the same image. The whole process takes just minutes.
Results are presented in a web-based interface where technologists can efficiently confirm the presence of bacteria and other objects of interest and, if required, their prevalence.
They can also add notes or request an additional consult. Final results of the analysis are then sent to their LIS.
