Fusion Parasitology Suite
Overview
The Techcyte Wet Mount Iodine solution is an AI-assisted screening tool designed to help medical technologists locate, count, and pre-classify parasites from iodine-stained fecal slides with greater accuracy and efficiency.
For Research Use Only
The solution will classify and count the following objects (for a full list see below):
Parasite cysts
Parasite trophozoites
Helminths
Challenges & Solutions
Laboratory technologists analyzing wet mount iodine-stained slides for parasites face a difficult task. Most of the samples are negative, it takes a high amount of specialized training, and looking through a microscope all day can be laborious.
The Techcyte solution digitizes the samples and uses AI-powered analysis to enhance diagnostic accuracy, streamline the reporting process, and improve the working conditions of the medical technologists performing the reads.
How it works
4-step process:
Prepare slides
Lab techs prepare the slides using a fecal concentration device. The Apacor Mini or Midi Parasep are recommended. A specialized mounting media is added to the slide to lengthen slide life to two hours and improve the visibility of the parasites. Slides are then coverslipped for scanning.
Scan slides
Technicians load slides into a supported scanner. The scanner scans the slide and produces a high-quality 40x image, which is automatically uploaded to the Techcyte platform for AI analysis.
Process images
The AI algorithm uses a convolutional neural network to find ova, parasites, and other diagnostically significant objects. It classifies and presents them for technologist review. The scanning and processing only takes a few minutes.
Review results
Technologists log into Techcyte on a web browser and review the scanned images, confirming the presence of objects of interest and, if required, their prevalence and size. They can also add notes or request an additional consultation.
Positive samples are manually reviewed by technologists who confirm the assessment on the microscope and report their results in their LIS.

Transforming the practice of pathology
Overview
The Techcyte Trichrome solution is an assisted screening tool designed to help medical technologists read fecal slides more efficiently and accurately using an AI-based algorithm and workflow.
For Research Use Only in the U.S.

The solution will classify, count and present the following objects for confirmation by a technologist (for a full list, see below):
Parasite cysts
Parasite trophozoites
Red blood cells
White blood cells
Yeast
Challenges & Solutions
Studies show that up to 98% of Trichrome-stained slides are negative 1.Reading them requires skilled technologists who can be difficult to find and retain. It’s difficult and monotonous, and looking eight hours a day through a microscope can cause repetitive stress injuries.
The solution is designed to help technologists quickly eliminate negative samples using a web browser on a computer monitor, allowing them to focus on the positive cases.
How it works
4-step process:
Prepare slides
Scan slides
Technicians load slides into a compatible scanner. Slides are scanned and the resulting images are automatically uploaded to the Techcyte platform for AI analysis. The Trichrome solution uses 40x images from compatible scanners. (for a list of compatible scanners, see below).
Process images
The AI algorithm uses a convolutional neural network to find ova, parasites, and other diagnostically significant objects. It classifies and presents them for technologist review. The scanning and processing only takes a few minutes.
Review results

Overview
The Techcyte Modified Acid Fast solution is designed to help medical technologists read modified acid fast stained microscope slides more efficiently and accurately using an AI-based algorithm and workflow.
For Research Use Only in the U.S.
The solution will classify, count and present the following objects:
Cryptosporidium sp. oocysts
Cyclospora cayetanensis oocysts
Yeast
Challenges & Solutions
Cryptosporidium and Cyclospora are challenging to detect with routine stains like trichrome or wet mount iodine due to their small size and low prevalence. Coupled with a global shortage of skilled microscopy experts, these difficulties strain resources, reduce efficiency, and increase the risk of diagnostic inconsistencies.
The Techcyte solution leverages AI-powered analysis, automated workflows, and advanced digital imaging to enhance diagnostic accuracy, streamline processes, and alleviate resource constraints in laboratories. Additionally, it seamlessly complements our Trichrome and Wet Mount Iodine solutions.
