TEST PASSPORT · REVIEWED JULY 2026
Allergy skin testing + specific IgE
Test a credible history—not hundreds of foods without symptoms.Skin-prick and serum specific-IgE tests identify sensitization. Clinical allergy requires the history to match; supervised oral food challenge may be needed for diagnosis.
ACCESSClinic / performance labSkin response and/or blood
TURNAROUNDSame day to several daysProvider and location dependent
RELATIVE COST$$–$$$Total downstream cost matters
COMMERCE STATUSClinician pathwayAllergist consultation + targeted testing
HOW TO USE THIS PAGE
Decide whether this test deserves a place in your plan.
- 01Confirm the question
Be clear about what decision the result would change before ordering.
- 02Check fit and preparation
Review who it helps, who should pause and how to protect the quality of the signal.
- 03Plan the response
Know what you will do with a normal, abnormal or unclear result.
01 / WHO SHOULD TAKE IT
Fit the test to
the person.
Testing is useful when the result can change a real decision. These are educational selection criteria, not a diagnosis or personal order.- Screening broad panels without a reaction history
- Diagnosing intolerance from sensitization alone
- Home food challenges after a concerning reaction
02 / SIGNAL VS. STORY
What it tells you.
What it cannot.
01
IgE sensitization to selected allergens
02
Whether the history and test support avoidance or challenge
03
Potential candidates for specialist-directed treatment
01
False positives are common when panels are broad
02
A positive test does not predict reaction severity
03
Antihistamines can affect skin testing
03 / MARKERS + RANGES
Read the panel
without chasing flags.
The report should show its own method, units and laboratory reference interval. Clinical decision thresholds may be different from a lab interval. We do not invent a universal “optimal” range where authoritative guidance does not support one.Use the laboratory unit and method, then interpret with symptoms, trend and the decision this marker can change.

MEN, WOMEN + LIFE-STAGE CONTEXT
The correct range is personal context—not pink versus blue numbers.
Where biology differs, we call it out. Clinical interpretation should also reflect organs present, hormone therapy, pregnancy, age, medications and health history.
Pregnancy can change which procedures or challenges are appropriate; discuss medicines with the specialist.
Asthma control and reaction history matter more than sex for test selection and challenge safety.
04 / PREPARATION
Protect the quality
of the signal.
The best assay cannot rescue the wrong timing, wrong specimen or wrong question. Follow the ordering clinician and laboratory instructions when they differ from this general guide.Write down food/exposure, amount, timing, symptoms and treatment.
Ask the allergist about antihistamine holds; do not stop essential medicines without guidance.
Test only allergens supported by the history.
REPEAT CADENCEOnce per defined question; retest only when the specialist expects it to change avoidance, challenge or treatment.
05 / AFTER THE RESULT
Turn the number
into a next step.
- 01
Interpret sensitization with the history
- 02
Use supervised challenge when appropriate
- 03
Create an emergency action plan for confirmed serious allergy
DO NOT WAIT ON A CONSUMER TEST
Trouble breathing, throat tightness, faintness or multi-system reaction is an emergency
