Our HF Systems scan human fecal (HF) microscope slides and analyze them using our HF algorithm. The algorithm presents predicted images for target organisms.
Fecal Ova & Parasite Detection
Overview
Our revolutionary Human Fecal Trichrome (HFT) algorithm finds, counts, and pre-classifies human fecal parasites from a digital image, including parasite cysts, parasite trophozoites, red blood cells, white blood cells and yeast from a digital image produced by a high-definition digital slide scanner.
This cutting-edge technology helps lower labor costs by reducing technician read time from 3-5 minutes to under 30 seconds per slide while improving accuracy and consistency.
It is the first AI-based Trichrome screening tool, AI-based MAF screening tool, and wet-mount iodine screening tool on the market today.
Challenge & Solution
Techcyte helps laboratories perform faster Ova and Parasite (O&P) stool examinations by eliminating negative samples and identifying ova and parasites in stool.
How it Works
Techs prep slides following the current CDC guidelines to concentrate the sample, then a standard trichrome or Modified Acid Fast CDC staining protocol.
Techs loads slides into the chosen scanner. Images are then scanned and automatically uploaded to the Techcyte cloud for processing. Processing time varies according to the number of slides.
Our AI algorithm analyzes the uploaded images, locating, classifying, and listing parasites in order confidence in a user interface designed for efficient review.
A technologist logs into Techcyte on any web-enabled device and reviews samples assigned to them, confirming presence of objects of interest and, if required, their prevalence. They can also add notes.
Positive samples are manually reviewed by a technologist who confirms the assessment on the microscope and logs results into their LIS.
See below list for a full overview of the organisms our technology is capable of identifying:
Trichrome
- Blastocystis sp.
- Giardia duodenalis
- Combined D.frag, Ib, E.nana troph
- Dientamoeba fragilis
- Endolimax nana
- Iodamoeba buetschlii
- Entamoeba hartmanni
- Entamoeba sp.
- Entamoeba coli
- Entamoeba polecki
- Entamoeba histolytica-complex (4 other morphologically similar species)
- Chilomastix mesnili
- Cyclospora cayetanensis (advisory)
- White Blood Cells
- Red Blood Cells
Modified Acid Fast (MAF)
- Cryptosporidium sp. oocysts
- Cyclospora cayetanensis oocysts
Benefits
Improved working conditions: Performing direct microscopic exams requires technicians to be highly alert for long periods of time. Our AI-assisted solution reduces technician stress and fatigue throughout their day.
5x more sensitive: We are five times more sensitive than manual examination. As an example, the Trichrome solution has a sensitivity rate of 98.9% and a slide-level specificity rate of 98.1%.
Improved consistency: AI has no daily cycle of fatigue, susceptibility to distraction, or confirmation bias from samples or prep/stain variation, and avoids issues with low prevalence samples.
Higher added value from technicians: We help lab techs be able to spend more time analyzing more difficult cases or increase throughput.
From negative to positive contribution margins: Our solution helps labs improve their contribution margins for fecal O&P testing.
