Serum levels are normally less than 11.5 ng/mL. [7] Elevated levels of serum tryptase occur in both anaphylactic and anaphylactoid reactions, but a negative test does not exclude anaphylaxis . Tryptase is less likely to be elevated in food allergy reactions as opposed to other causes of anaphylaxis.
Normal blood levels of alpha-1 antitrypsin may vary with analytical method but are typically around 1.0-2.7 g/L. [17] In individuals with PiSS, PiMZ and PiSZ genotypes, blood levels of A1AT are reduced to between 40 and 60% of normal levels; this is usually sufficient to protect the lungs from the effects of elastase in people who do not smoke.

Total serum tryptase is elevated in mast cell leukemia. Normal total (alpha + beta) serum tryptase is approximately 6 micro g/L (range 0 to 11 micro g/L). Values of several hundred micro g/L are characteristic of mast cell leukemia. [12] Plasma and urinary histamine levels are frequently elevated in mast cell leukemia.

Over 100 different variants of α 1-antitrypsin have been described in various populations.North-Western Europeans are most at risk for carrying one of the most common mutant forms of A1AT, the Z mutation (Glu342Lys on M1A, rs28929474).
The over-60s usually have different skincare concerns, such as drier and thinner skin, so it's important to choose products with ingredients that focus on those symptoms.
