This test is designed to detect the presence of IgG antibodies that are generated in response to the consumption of certain foods. IgG reactivity is analyzed for 108 different foods and the results are classified into three groups – low reactivity, moderate reactivity, and high reactivity. Foods that are in the high reactivity category may be contributing to various symptoms, including headaches, gastrointestinal discomfort, and skin issues. Further analyses of these specific foods can then be conducted including in an elimination diet.

Preparation Before Specimen Collection


Specimen Type



50 μL in a microtainer


Microtainer (regular blood tube)

Collection Method

This test requires a blood sample from a finger prick. All supplies for sample collection are provided in the kit.

  1. First wash and dry hands. Warm hands aid in blood collection.
  2. Clean the finger prick site with the alcohol swab and allow to air dry.
  3. Use the provided lancet to puncture the skin in one quick, continuous and deliberate stroke.
  4. Wipe away the first drop of blood.
  5. Massage hand and finger to increase blood flow to the puncture site. Angle arm and hand downwards to facilitate blood collection on the fingertip.
  6. Drip blood into the microtainer tube.
  7. Dispose of all sharps safely and return sample to the laboratory in the provided prepaid return shipping envelope.

NOTES: Avoid squeezing or ‘milking’ the finger excessively. If more blood is required and blood flow stops, perform a second skin puncture on another finger. Do not touch the fingertip.

Specimen Storage

Maintain specimen at temperatures between 2°C and 30°C during storage and transport.

Specimen Stability

Blood samples can be refrigerated or kept at room temperature for up to 7 days.

Causes for Rejection

  • Incorrect or incomplete patient identification
  • Incorrect specimen collection
  • Inappropriate storage and transport conditions
  • Incorrect specimen volume



To aid in the identification of foods that may be contributing to various symptoms, including headaches, gastrointestinal discomfort, and skin issues.
