Tryptase CNV Test - Clinical

Elevated serum tryptase levels have been associated with a wide range of multi symptom complaints including:

1. Cutaneous flushing, itching and severe allergic reactions
2. Dysautonomia
3. Functional gastrointestinal symptoms
4. Chronic pain
5. Connective tissue abnormalities

A recent NIH study1 found that inherited increases in serum tryptase levels correlated with duplications (and triplications) of the gene encoding α-tryptase (TPSAB1).

Based on the results of this study, Gene By Gene has developed a clinical assay to identify people with multiple copies of α-tryptase. The test is now available for the out-of-pocket cost of $169*. For more information or to order the test, please contact Gene By Gene at tryptase@genebygene.com or (832)-761-9643.

*This test is not offered direct to consumer (DTC). It must be authorized by a qualified medical professional.
