Find out what you're
actually allergic to.
Supervised drug challenges. Board-certified allergists.
Answers in one visit.
What happens
before you arrive.
The challenge itself is a single morning. The preparation is what makes it safe — and what lets your allergist walk in already knowing your history.
Submit your medical records
Upload prior allergy notes, reaction descriptions, or your chart summary. Our clinical team reviews everything before your appointment — no surprises on the day.
Complete the drug history questionnaire
A 12-question intake covering the suspected drug, the original reaction, any re-exposures, and current medications. Takes 8 minutes. Completable from your phone.
Receive your pre-challenge briefing
Your allergist reviews your file and calls you 48 hours before your appointment to confirm protocol, answer questions, and clear any same-day contraindications.
Pre-challenge review
Completed 48 hrs before your visit
Your records are reviewed by your allergist — not a triage algorithm.
Every intake is read by the physician who will conduct your challenge. They know your chart before you walk in the door.
What happens
in the room.
A graded oral challenge is not a provocation test. It is a controlled, step-wise administration of increasing doses under continuous clinical supervision — designed to catch any reaction at its earliest and mildest signal.
Challenge Day Protocol — Illustrated Timeline
* Protocol may vary based on pre-challenge review findings. Your allergist will confirm your specific schedule.
Continuous cardiac monitoring
Pulse oximetry and ECG throughout the procedure.
Epinephrine on the counter
Not in a cabinet. On the counter. Beside the physician.
Two-clinician protocol
Your allergist and a dedicated RN present for every graded dose.
Graded dose escalation
Starting at 1% of therapeutic dose — not the full amount.
What you leave
with.
A typed, physician-signed allergy status letter — not a handwritten note, not an addendum to your chart. A formal clinical document that travels with you.
Formal allergy status determination
Cleared, confirmed, or inconclusive — with clinical rationale for each finding.
Physician signature and NPI number
Accepted by hospital admissions, pharmacy systems, and surgical pre-op coordinators.
Safe alternative medications listed
If a reaction is confirmed, your letter includes tested-safe alternatives for common procedures.
Electronic copy sent to your PCP
Your primary care physician receives a copy automatically. No faxing required on your end.
