Fecal Ova & Parasite Detection

AI-assisted screening tool that reduces technologist average read time from 5 minutes to under 30 seconds.

Overview

Our Human Fecal Ova & Parasite (O&P) Detection solution is a revolutionary screening tool that is being developed to help medical technologists read fecal slides more efficiently and accurately using our AI-based algorithm, lab-optimized workflow, and LIS integration.
For Research Use Only in the U.S.
CE-IVDD marked in Europe

Our O&P solution will classify and count the following objects (for a full list see below):

Decoration Icon check Parasite cysts
Decoration Icon check Parasite trophozoites
Decoration Icon check Red blood cells
Decoration Icon check White blood cells
Decoration Icon check Yeast

Challenges & Solutions

Up to 95% of O&P cases are negative. Reading them requires skilled technologists that can be difficult to find and retain. It’s monotonous, and peering eight hours a day through a microscope can cause repetitive stress injuries.

Our solution helps technologists quickly eliminate negative samples using a computer monitor, allowing them to focus more on the positive cases.

How it works

4-step process:

Prepare slides

Lab tech preps slides using an Apacor Mini or Midi Parasep to concentrate the sample, then follow a standard Trichrome or Modified Acid Fast CDC staining protocol. Slides are then coverslipped for scanning.

Scan slides

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. Our Trichrome and modified acid fast (MAF) O&P fecal tests accept any good-quality 80x image from a compatible scanner (for a list of compatible scanners, see below). Our wet mount iodine solution is under development and will accept 40x images.

Process images

Our AI algorithm uses a convolutional neural network to identify differentiating features and determine which combinations indicate a certain ova, parasites, 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.

Review results

A technologist logs into Techcyte on any web-enabled device and reviews available samples, confirming presence of objects of interest and, if required, their prevalence. They can also add notes or request an additional consult.

Positive samples are manually reviewed by a technologist who confirms the assessment on the microscope and confirms results in their LIS.
