vet-translator

Decode veterinary visit notes, discharge summaries, and lab panels (CBC, chemistry, urinalysis) into plain language: what each value means, which results are actually abnormal for the animal's species/breed/age, flag concerning trends across visits, and generate a question list for the next appointment. Use when the user shares vet notes or bloodwork for a pet and asks what it means, whether results are normal, or wants trends tracked over time.

Vet visit summaries are written in clinical shorthand for other clinicians — "Hx s/p OVH, BUN 34↑, USG 1.020, r/o early CKD, recheck SDMA in 4-6 wks". Owners nod, pay, go home, and google each term at midnight. vet-translator decodes those notes and lab panels into plain language, evaluates each value against species-specific (and where relevant breed/age-aware) reference ranges, separates "actually abnormal and worth watching" from "normal for this animal", tracks trends across visits, and writes the question list for the next appointment.

Overview

The core of the skill is a veterinary reference-range engine (scripts/vet_translator.py):

• Abbreviation decoder — 120+ veterinary shorthand terms (s/p, Hx, r/o, DVM-ese like "BAR", "MM pink/moist", "BCS 7/9") mapped to plain-language explanations
• Lab panel evaluator — CBC, chemistry, and urinalysis markers with canine/feline reference ranges; flags low / normal / high / critical for the animal's species, and breeds with known physiological quirks (sighthounds run high creatinine; greyhounds run low platelets and high WBC; sled dogs differ too)
• Trend tracker — feed it multiple visits' results for the same patient; it computes direction of change and flags values that are normal but drifting (early kidney decline hides as "still in range but up 40% from last year")
• IRIS CKD staging — creatinine + SDMA + UPC + blood pressure → chronic kidney disease stage for cats and dogs, the single most common geriatric finding
• Appointment question generator — turns findings into a prioritized question list ("Ask: should we recheck SDMA in 4 weeks given the trend?")

Medical disclaimer: this skill explains and organizes; it does not diagnose or replace the attending veterinarian. Every output states this.

When to Use

• User pastes/photos vet discharge notes and asks "what does this mean?"
• User shares bloodwork results and asks whether values are normal
• A pet has a chronic condition (CKD, hyperthyroidism, diabetes, arthritis) and the user wants to track values across visits
• Preparing for a follow-up appointment: "what should I ask about?"
• Comparing a second opinion's labwork against the first clinic's

Don't use for: emergency triage (pet is visibly sick → vet NOW, not a lab decoder), prescribing, dosage calculations for prescription drugs, or contradicting the attending vet's diagnosis.

How It Works

1. Extract — take the user's text (typed or OCR'd from photos), pull out abbreviations, numeric results with units, and visit dates.
2. Decode — expand shorthand to plain language; each term gets a "what it is" and "why the vet mentions it" sentence.
3. Evaluate — match each numeric result to its species reference range; breed corrections apply where known (greyhound, sled-dog, Persian-cat PKD screening context, age-adjusted SDMA in seniors).
4. Stage & correlate — run IRIS CKD staging when kidney markers are present; link related markers (e.g., elevated SDMA + poorly concentrated urine + weight loss = the classic early-CKD triad in cats).
5. Trend — if multiple visits provided, compute deltas and flag drift.
6. Report — plain-language summary (5th-grade reading level), abnormal-findings table sorted by importance, trend section, and a "questions for your vet" list.

Quick Start

bash

# Translate a visit note
python3 scripts/vet_translator.py explain --text "Barney, 12y MC cat. Hx weight loss. BCS 5/9. \
CBC WNL. Chem: BUN 38, CREA 2.8, SDMA 28, ALT 92. USG 1.014. r/o CKD; recheck in 4 wks."

# Evaluate a lab panel against species ranges
python3 scripts/vet_translator.py labs --species dog --results "CREA 1.2 mg/dL, BUN 28, ALP 210, PLT 110"

# Track a value across visits (trend + drift detection)
python3 scripts/vet_translator.py trend --marker SDMA --species cat \
  --series "2024-01:10,2024-07:14,2025-01:19,2025-07:26"

# Full IRIS CKD staging
python3 scripts/vet_translator.py ckd --species cat --crea 2.8 --sdma 28 --upc 0.4 --bp 150

Steps (Agent Workflow)

1. Ask for: species, breed, age, the note/results text, and any prior visit results if trend matters.
2. Run explain on narrative notes, labs on tabular results — or both on the same input (they compose).
3. If kidney values present → run ckd staging; if multiple visits → run trend on the key markers.
4. Present: plain-language explanation first, abnormal findings table second, then the vet-question list.
5. Always include the disclaimer and the "confirm with your veterinarian" framing — never present interpretation as diagnosis.

Output Shape

text

PLAIN-LANGUAGE SUMMARY — Barney (12y male cat, neutered)
  Visit note decoded: weight-loss history, body condition normal (5/9).
  Bloodwork pattern matches early-to-moderate kidney decline (CKD).

ABNORMAL FINDINGS (importance order)
  1. SDMA 28 µg/dL        HIGH (ref 0-14)  — kidney function marker; earlier
                          and more sensitive than creatinine in cats
  2. Creatinine 2.8 mg/dL HIGH (ref 0.8-2.4) — with SDMA 28 and dilute urine,
                          consistent with IRIS CKD Stage 2 (see staging)
  3. BUN 38 mg/dL         HIGH (ref 16-36) — affected by diet/hydration too;
                          milder concern than the two above
  4. ALT 92 U/L           HIGH (ref 10-100 → borderline 92 is essentially
                          normal; many labs cap at 100) — no action alone

IRIS CKD STAGE 2 (non-proteinuric, BP normal-ish)
  ...

QUESTIONS FOR YOUR VET
  1. Given SDMA 28 + CREA 2.8, when should we recheck — 4 weeks as written?
  2. Should Barney start a kidney-support diet now or wait for the recheck?
  ...
This is educational interpretation, not a diagnosis. Confirm with your veterinarian.

Common Pitfalls

1. Applying human reference ranges to pets. Dog creatinine 2.8 is stage-3 territory; a human's 2.8 is dialysis talk. Always set --species first.
2. Ignoring breed physiology. Greyhound creatinine 1.5-2.1 is normal (lean muscle); greyhound platelets 110k can be normal. Evaluating a sighthound with generic dog ranges manufactures false alarms.
3. Treating every out-of-range value as a crisis. Mild ALT/ALP bumps in an otherwise well animal are often incidental. The report sorts by importance; keep that ordering when summarizing.
4. Missing the trend because values are "in range". A cat's creatinine going 1.0 → 1.6 → 2.2 across a year is rising through the normal range — that's early CKD until proven otherwise. Use trend whenever history exists.
5. Unit confusion. mg/dL vs mmol/L (creatinine, glucose), g/dL vs g/L (hemoglobin, albumin). The script flags unit mismatches; never silently convert without the unit stated.
6. Overstepping into diagnosis/prescribing. This skill explains, stages per published guidelines, and prepares questions. It does not tell the user what treatment to start — that's the attending vet's call.

Verification Checklist

• Species (and breed if a quirk-prone breed) passed to every command
• Units confirmed for every numeric result before evaluation
• Trend run when more than one visit's results are available
• Output includes the "confirm with your veterinarian" disclaimer
• Question list generated for follow-up appointments

One-Shot Recipes

"Cat bloodwork: CREA 2.4, SDMA 22, USG 1.015 — is this bad?"

bash

python3 scripts/vet_translator.py labs --species cat --results "CREA 2.4, SDMA 22" --urine "USG 1.015"
python3 scripts/vet_translator.py ckd --species cat --crea 2.4 --sdma 22
# → Stage 2 CKD pattern; questions list emphasizes diet + recheck interval

"My greyhound's PLT came back 118 and CREA 1.7 — vet wants more tests"

bash

python3 scripts/vet_translator.py labs --species dog --breed greyhound --results "PLT 118, CREA 1.7"
# → both normal for the breed; questions list: which tests, and what would change management
