Levels of total tryptase in serum greater than or equal to 11.5 ng/mL may indicate mast cell activation occurring as a result of anaphylaxis or allergen challenge, or it may indicate increased number of mast cells as seen in patients with mastocytosis. Also, treatment may only be partially successful, but unfortunately there are no randomized clinical trials yet to show definitive treatments that work for hereditary alpha tryptasemia syndrome. Again, we do not yet have the answer. 4,5 In addition to having higher blood tryptase levels, individuals with more alpha tryptase copies also report more shared symptoms.

After washing, enzyme-labeled antibodies against tryptase are added to form a complex. That means that heredity isn't the only cause of bipolar disorder. Hereditary alpha-tryptasemia (HT) is a genetic trait characterized by multiple copies of the TPSAB1 gene, which encodes alpha-tryptase. Because that means that there could bemillions of people carrying multiple copies of the alpha tryptase gene, it should come as no surprise that some people will have more than one explanation for their symptoms. Tryptase, Serum Useful For Evaluation of individuals with suspected mast cell activation, which may occur as a result of anaphylaxis or allergen challenge Evaluation of patients with suspected cutaneous or systemic mastocytosis Testing Algorithm For more information, see Mast Cell Disorder: Diagnostic Algorithm, Bone Marrow Special Instructions A previous bone marrow transplant from an allogenic donor will interfere with testing. 1 The prevalence of this condition has been estimated as 4% to 6% of the White population.

In addition, a polymerase chain reaction-based assay is used to detect the presence of the alpha-3.7 and alpha-4.2 deletions. Alpha-thalassemia occurs in all ethnic groups but is especially common in individuals of Southeast Asian and African ancestry. Any other medical or psychiatric condition that, in the opinion of the Investigator, would compromise patient safety, or interfere with the objectives of the protocol or completion of treatment per protocol. Less frequently, alpha-thalassemia results from single point alterations, such as hemoglobin Constant Spring (HBA2: c.427T >C). Good coordination within your team can prevent unnecessary medical tests and can lead to better outcomes. The alpha form of human tryptase is the predominant type present in blood at baseline in normal subjects and is elevated in those with systemic mastocytosis. It is also possible that the increased tryptase itself causes the symptoms without requiring mast cells to be activated, or it could cause an abnormally increased response to otherwise normal mast cell activation, which might explain why so many patients respond to medications that target mast cells and substances released by mast cells. Fifteen probes that hybridize throughout the alpha-globin locus from the HS40 promoter region through the 3'HVR region are utilized in order to maximize the information needed to map the approximate location of nearly all DNA deletions that occur. Researchers from participating institutions use the database to search for and invite patients or healthy volunteers who meet their study criteria to participate.
