The UKnow Peanut Test, aka “resolved component testing,” utilizes a technique developed by PiRL laboratory in Michigan, a division of Thermofisher Diagnostics, which allows for a more precise way to test for a peanut allergy. It is the first and only FDA-approved allergen component test for peanuts.

Isolates specific proteins for precise diagnosis

As opposed to the skin test, the UKnow Peanut Test is a blood test that isolates specific proteins in the peanut in order to find out which proteins are dangerous for a person to have and which are most likely cross-reactions to another allergen protein, such as pollen.

A study published in The Journal of Allergy and Clinical Immunology by Nicholau et al., showed that patients suspected of having a peanut allergy were more likely to have a severe allergic reaction to peanuts if their blood count was elevated for the proteins Ara h1, Ara h2 and Ara h3.

The test identifies these three proteins. The Ara h2, in particular, was linked to severe peanut allergy. This test should be ordered for patients concerned about peanut allergy.

Eliminates uncertainty and provides confidence

The test could be a good fit for you if you have had a positive blood or skin test for peanut allergy in the past, if you have a family history of peanut allergy, if you suspect a peanut allergy because of a past experience involving mild to severe symptoms, or if you have a confirmed peanut allergy with a history of mild to moderate symptoms.

Many children live restricted lives, limiting their diet and their social activities because of peanut allergy. Parents live with fear and need to be vigilant against possible exposures. uKnow could bring clarity to an uncertain diagnosis.
