Dr. Umesh KrishnaFounder & Developer
Designed by a Pathologist.
Built for modern laboratories.
I’m Dr. Umesh Krishna, a practicing pathologist. HemaSync began as a personal project to make the manual differential counting I perform regularly faster, more consistent, and less tedious, while keeping interpretation and decision-making firmly in the hands of the pathologist.
I began developing HemaSync as an independent project because useful laboratory tools should not be limited to institutions that can afford expensive proprietary systems. It is my contribution to the community of pathologists, trainees, and laboratory professionals I am part of—created in response to real workflow challenges encountered in everyday practice.
HemaSync is built around a human-first principle: AI assists; professional judgment remains with the pathologist.

Product answers
A few clear answers.
Product
What is HemaSync?
HemaSync is a digital hematology workflow tool for recording manual differential counts and organizing case work. It supports peripheral blood and bone marrow workflows, with optional voice input and AI-assisted insight. The professional examining the specimen identifies the cells.
Who is HemaSync for?
HemaSync is designed for pathologists, pathology trainees, and laboratory professionals who perform or review manual differential counts. It supports their workflow and does not replace training, laboratory protocols, or independent professional judgment.
What does HemaSync do?
It lets a user record and track identified blood or marrow cells toward a selected count target, organize case details, and optionally use voice entry or AI-assisted analysis. Cell identification and clinical interpretation remain with the healthcare professional.
Is HemaSync a hematology differential cell counter?
Yes. HemaSync is a digital cell-counting tool for manual hematology differentials. The user examines the specimen and selects the cell type; HemaSync records the count and helps organize the workflow. It does not automatically identify cells from an image.
Counting, voice, and AI
What is manual differential counting?
Manual differential counting is identifying and tallying cells while examining a specimen. HemaSync records the observations and tracks progress toward a selected count target; the person examining the specimen identifies each cell.
Can HemaSync be used for peripheral blood differential counting?
Yes. HemaSync supports manual differential counting for peripheral blood smears. The user records the cells they identify and reviews the resulting count in the specimen and clinical context.
Can HemaSync be used for bone marrow differential counting?
Yes. HemaSync supports manual differential counting for bone marrow examinations. It records and organizes the user's observations; it does not determine cell identity or replace morphological assessment.
Does HemaSync support voice-assisted counting?
Yes. Voice input provides a hands-free way to record supported cell types while examining a specimen. Review the on-screen count to confirm each spoken entry was captured correctly.
Does HemaSync provide AI-assisted analysis?
Yes. Optional AI Analysis can generate a structured interpretation from a manual differential count. Its output may be incomplete or incorrect and should be checked against the smear, patient context, and applicable laboratory standards.
Does HemaSync AI replace a pathologist?
No. HemaSync and its optional AI features support workflow; they do not replace a pathologist or other qualified healthcare professional. Cell identification, interpretation, follow-up testing, and diagnostic decisions remain with the professional responsible for the case. See the medical disclaimer.
Which count targets does HemaSync offer?
HemaSync offers 100-, 200-, and 500-cell targets, plus a free-count option. The user selects a target to suit the examination and laboratory workflow; the software does not recommend a clinically appropriate count size.
How do HemaSync AI credits work?
AI-assisted insights use credits. A free monthly allowance and paid credit top-ups are currently described in the product. Check the app for current allowance and purchase terms. Manual counting does not require AI credits.
