ValleySense

How ValleySense works

Valley fever looks like other lung infections, so it often goes untested for weeks. ValleySense helps patients know when to see a doctor and what to ask, and helps doctors decide when to order the valley fever blood test.

01Patients, about 3 minutes

The patient journey

  1. Step 01

    Check for warning signs

    Trouble breathing, severe chest pain, or confusion? ValleySense tells you to call 911 and stops. Nothing is saved.

  2. Step 02

    Answer short questions

    How long you've been sick, your symptoms, recent dust or digging nearby, and things that raise your risk.

  3. Step 03

    Record 5 seconds of coughing

    Or upload a clip, or skip it. The recording is checked and then thrown away. It is never saved.

  4. Step 04

    See how soon to see a doctor

    You get an urgency level and a plain valley fever signal: Low, Moderate, or High. No percentages.

  5. Step 05

    Find care and know what to ask

    Open a map of urgent care nearby. If your signal calls for it, ask: “Can you test me for valley fever?”

  6. Step 06

    Share a card with your doctor

    If you choose to save, you get an ID, a PIN, and a QR code. Your answers are deleted after 30 days.

02Clinicians, about 1 minute

The doctor journey

  1. Step 01

    Scan or type the ID

    The QR code opens ValleySense with the survey ID filled in. It never contains the PIN.

  2. Step 02

    Enter the PIN and read the briefing

    Symptoms, duration, exposures, risk groups, the cough analysis, and what the patient was told.

  3. Step 03

    Add what you know (optional)

    Working diagnosis, days since onset, eosinophilia, erythema nodosum, adenopathy, prior serology.

  4. Step 04

    Add a chest X-ray (optional)

    Resized in the browser, run through the team's X-ray model, and discarded. Nothing is stored.

  5. Step 05

    Get a likelihood and a testing recommendation

    A valley fever likelihood with every factor and its likelihood ratio, plus whether to order cocci serology and when to retest.

  6. Step 06

    Export the PDF

    The PDF is the record: briefing, inputs, assessment, and heatmap. ValleySense keeps none of the clinician's inputs.

03The models

What the models do, and don't do

ValleySense never diagnoses. It recommends when to see a doctor and when to order the valley fever blood test (cocci serology).

  • Pretrained

    Cough detector

    DoesChecks whether a recording contains a cough at all.

    Doesn'tDoesn't say what caused the cough.

  • Built by our team

    Dry/wet cough model

    DoesEstimates whether a detected cough is dry or wet. Most valley fever coughs are dry.

    Doesn'tDoesn't detect valley fever. A dry cough is only a weak clue.

  • Built by our team

    Chest X-ray model

    DoesScores findings on a frontal chest X-ray and shows where it looked.

    Doesn'tDoesn't read the X-ray for the doctor or name a disease.

  • Transparent rules

    Risk engine

    DoesCombines answers, findings, and model outputs into a likelihood, showing every factor.

    Doesn'tDoesn't replace the blood test. Only serology confirms valley fever.

If you have trouble breathing, severe chest pain, or confusion, call 911.
