What does Workup do?

Workup runs AI-powered cardiac measurement (VHS/VLAS) from a photo of a thoracic radiograph, predicts urine specific gravity from bloodwork (public beta), and bundles seven clinical calculators — CRI, fluid therapy, chemo BSA, transfusion, RER, HHS, Pro-Sal. Results can be exported as client-friendly PDF handouts.

How accurate is the VHS/VLAS measurement?

The underlying AI was trained on veterinary radiographs with input from practicing veterinarians. Accuracy is characterized in our preprint (bioRxiv 10.1101/2025.11.13.688321): https://www.biorxiv.org/content/10.1101/2025.11.13.688321v2. Every result in the app shows both the score and a quality tier (Good / Fair / Low) derived from landmark confidence. Treat low-tier results as "needs manual review." You can edit landmarks manually on the result screen at any time.

What breeds are supported for VHS reference?

21 breeds with published normal VHS ranges, plus a generic "dog" fallback. The result screen shows whether the measured VHS is within, above, or below the breed-specific normal range. Complete breed list available inside the app under Tools → Breed VHS Reference.

Is the USG Predictor ready for clinical decisions?

No — USG screening is in public beta. The algorithm is under real-world evaluation for detecting otherwise normal bloodwork patterns that may indicate impaired kidney function. Use it as a screening prompt, not a replacement for urinalysis. Contributing feedback at radanalyzer.com/contact/ helps improve the model.

What bloodwork values does the USG Predictor need?

Five values: patient age (years), BUN, creatinine, hemoglobin, and absolute lymphocytes. Species-agnostic (trained across dogs and cats). The result shows how much each input pushed the prediction toward higher or lower USG, so you can sanity-check the model against the clinical picture.

How much does Workup cost?

Free tier gives 3 uses per month of any AI algorithm (VHS/VLAS or USG Predictor), plus unlimited use of the seven clinical calculators and breed reference. Pro unlocks unlimited VHS/VLAS + USG Predictor use, unlimited scan history, and PDF handout exports. Clinics can purchase a seat license that shares Pro across the whole team — verified via work email, no per-seat checkout.

Does Workup store my radiographs?

Images used for VHS/VLAS scans are sent to our inference backend for processing and are not retained beyond the session. Scan results (score, landmarks, metadata) are stored on-device and optionally in your account for history review. See our privacy policy for full details.

Why does Workup need camera and photo permissions?

Camera access is required for live radiograph capture. Photo library access is required if you want to analyze an existing radiograph image instead of capturing one live. Both can be revoked at any time via your device settings; the rest of the app still works.

I found a bug or have feedback.

Email tomas.reyes@radanalyzer.com or use the contact form. Please include your device model, iOS/Android version, and a short description. If the issue happened during a scan, note the approximate time so we can correlate with server logs.

Can I use Workup offline?

Clinical calculators work fully offline. VHS/VLAS scans and USG predictions require a network connection for inference. If you lose connectivity mid-scan, the app surfaces a clear offline banner and lets you retry when reconnected.
