Preparing for Your Test & Collecting Your Specimen(s)

Do I need to fast before my blood draw?
No. It is suggested to maintain your usual dietary habits consuming a variety of foods when possible. Avoid any food that may have potentially resulted in a previous adverse reaction or anaphylaxis. Secondary exposure may be life-threatening.

Are there any supplement or medication restrictions before collecting my blood specimen?
Immunosuppressive drugs such as oral or intranasal corticosteroids (prednisone, beclomethasone, fluticasone, triamcinolone), and topical cortisone suspensions and creams, may affect test results. The suggested time period to abstain from these is 4 weeks. However, the dosage, route, half-life of medication, and duration of administration on systemic immune response, can vary on its effects. Please contact your practitioner for their specific guidelines.

Are there any food, supplement or medication restrictions before collecting my urine specimen?
For the Environmental Pollutants Profile:

Sorbic Acid/Sorbate (E 200-203) and Benzoic Acid/Sodium Benzoate (E 210-213).
Please contact your practitioner for their specific guidelines.

Where do I get my blood drawn?
Your practitioner may be equipped to draw your blood in office or he/she may send you to a draw station. The draw station may charge you a fee for their service.
