What does Workup do?
Workup runs AI-powered cardiac measurement (VHS/VLAS) from a photo of a canine thoracic radiograph, predicts feline urine specific gravity from bloodwork (currently in pilot), 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 — feline USG screening is currently in pilot. The algorithm is under real-world evaluation for detecting otherwise normal bloodwork patterns that may indicate impaired kidney function in cats. Use it as a screening prompt to flag cats that need urinalysis, not as a replacement for urinalysis. A multi-site validation study is being planned with an academic veterinary medicine partner. 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. The model is trained on feline data only — it is intended for use in cats. A canine version is in development. 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?
Workup includes a 30-day free trial with full access to every feature — VHS/VLAS, USG Predictor, calculators, and PDF handouts. After the trial, pick the plan that fits: $2.99/week, $9.99/month, or $99.99/year (about $8.33/month, billed annually). Your trial begins when you start your subscription in the app — no charge until day 31. Cancel anytime in your App Store or Google Play subscription settings.
Do you offer team or enterprise pricing?
Yes. For veterinary teams and multi-DVM hospital groups, Workup Enterprise adds cross-site visibility, identity-based access control, and a contract behind every AI-assisted decision — priced to your group’s size and setup. We don’t publish a seat price; pricing is sized to your deployment. See the Workup for teams page (workup.vet/teams/) or contact us for enterprise pricing.
Does Workup store my radiographs?
Images used for VHS/VLAS scans are sent to our inference backend for processing and are retained for up to 24 hours, after which they are automatically deleted. The 24-hour window allows our team to investigate scan-quality issues if you flag a result. 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.
