Fecal Ova & Parasite Detection

Our HF Systems scan human fecal (HF) microscope slides and analyze them using our HF algorithm. The algorithm presents predicted images for target organisms.

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 on the market today. Additionally, the HFT algorithm is CE marked in the EU. The fecal algorithms are for investigation use only and not for diagnostic use in the US. Their performance has not been validated within the US.

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

How it Works

Our Trichrome O&P Fecal tests analyze any good-quality 80x image. Slides are prepared using a standard trichrome or modified acid fast prep. Our modified acid fast (MAF) and wet mount iodine solution are under development and will analyze 80x and 40x images, respectively.
We support the 3DHistech and the Hamamatsu S360 scanners for Trichrome, and the 3DHistech scanner for MAF. Our wet mount iodine solution plans to support the Hamamatsu S360, the Grundium OCUS 40, and the Motic EasyScan Pro1 scanners.

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 Trichrome algorithm analyzes the uploaded images, locating, classifying, and listing parasites in order of confidence in a user interface designed for efficient review. Our MAF and Iodine Wet Mount algorithms are being developed to do the same.

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:


  • 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) – under development

  • Cryptosporidium sp. oocysts
  • Cyclospora cayetanensis oocysts

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%, which was validated while obtaining CE marking in the EU.

*These claims have not been examined by the FDA. These results are from a single study in a US based reference lab.

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 Trichrome O&P testing.
