Karyotype real metaphase spreads in your browser

Work the way a cytogenetic technologist does. Every case starts as a G-banded metaphase spread: drag each chromosome into its place in the karyogram, rotate it upright and zoom in when the bands are hard to read.

  • Drag, rotate and zoom every chromosome
  • Ideograms and reference images one click away while you work
  • Save your progress and pick the case up later

Instant scoring

Know exactly which chromosomes you got right

Check your score whenever you are ready. Every placement is marked correct, partially correct or incorrect, so you see at once which pairs you confused and can fix them while the case is still in front of you.

  • Correct, partial and incorrect counts for the whole case
  • Each chromosome highlighted where it went wrong
  • Try again until the karyogram is right

Case library

120+ cases with clinically relevant ISCNs

Practice on the abnormalities you will meet in the lab. The library covers constitutional, prenatal and cancer-related karyotypes, from common trisomies to translocations, and every case comes with its ISCN result.

  • Complete G-banded metaphase spreads, not cropped examples
  • Numerical and structural abnormalities
  • ISCN notation for every case
Block & learning tests

Build identification speed, then test what you know

Block tests are rapid-fire chromosome identification challenges that train you to recognize each chromosome by its banding pattern and shape. Learning tests assess your knowledge in a structured way, and your scores are kept across attempts.

  • Rapid chromosome identification drills
  • Structured learning tests
  • Scores tracked across attempts
Reference materials

Ideograms and references beside every case

Check a banding pattern without leaving the case. Ideograms, banding references and chromosome-specific resources are built into the workbench, and educators can add reference images to each case that guide without giving the answer away.

  • Ideograms for every chromosome
  • Banding pattern references
  • Case reference images from your educator
Learn at your own pace

Practice anywhere, on your own schedule

Karyotutor runs in any modern browser, so you can practice at the bench, at home or between rotations. There are no deadlines: work through the fundamentals or push into harder cases whenever you are ready, and use the free Learning Hub to read up along the way.

  • Nothing to install, no plug-ins
  • Save and resume any case
  • Free guides and worked cases in the Learning Hub

Frequently Asked Questions

Do I need to install anything?

No. Karyotutor runs in any modern web browser on Windows, macOS or Linux. There is no software or plug-in to install.

What cases are included?

More than 120 cases covering constitutional, prenatal and cancer-related abnormalities. Each case is a complete G-banded metaphase spread with its clinically relevant ISCN result.

Is there a free trial?

Yes. You can create a free account with no card required. The trial includes a set of trial cases so you can try the workbench, scoring and reference tools before you upgrade.

Can Karyotutor help me prepare for cytogenetics certification?

Karyotutor gives you the volume of hands-on karyotyping practice that certification preparation needs. It is an independent training tool and is not affiliated with any certifying body. Our free cytogenetics certification prep guide covers what to study.

Can instructors assign cases and track trainees?

Yes. Educators can create classrooms, assign case batches and tests, review each trainee's completed karyotypes and see per-chromosome results across attempts. See Karyotutor for educators.

Can we use our own laboratory's cases?

Yes. Institutions can import their own metaphase images and cases so trainees practice on material from their own lab, alongside the existing case library.
