3gAllergy blood tests offer a simple, convenient, and accurate alternative to traditional allergy testing.


When it comes to testing for allergy, there are many things to consider. Patients may benefit from a single-blood draw (IMMULITE 3gAllergy), versus traditional skin-prick testing methods.  We’ve compiled answers to the most asked questions about allergy testing, diagnosis, and more.

Traditional Skin Prick Testing:

  • Allergens are scratched into patient’s skin
  • Potentially negative reactions are monitored
  • Patient must discontinue use of medications prior to testing
  • Sensitivity and specificity for food allergens range from 30-90% and 20-60%
  • Interpretation of test results is very subjective.
  • Can be potentially dangerous if severe reaction is triggered.

3gAllergy Blood Test:

  • Single blood draw measures lgE antibodies in blood.
  • A small amount of lgE antibodies is normal. A larger amount may indicate an allergy. 
  • Doesn’t require allergy discontinuation of medication or patient adherence to pretest instruction.
  • Enables component testing in food allergies by determining the exact triggering proteins.
  • Fewer false positives for patients with sensitive skin, hives, and eczema.
  • Standardized for more quantifiable results.
  • Can predict the severity of the allergy, as opposed to just its presence.

Let Siemens Healthineers help bring your patients peace of mind this school year by sending them for 3g Allergy blood testing with a single blood draw.
