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.

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.
"Providers are encouraged to consult with their local lab(s) to obtain hormone level reference ranges for both 'male' and 'female' norms, [which can vary,] and then apply the correct range when interpreting results based on the current hormonal sex, rather than the sex of registration."
Eosinopenia is a condition where the number of eosinophils, a type of white blood cell, in circulating blood is lower than normal. [1] Eosinophils are a type of granulocyte and consequently from the same cellular lineage as neutrophils, basophils, and mast cells.
Tryptase alpha-1 and tryptase beta-1 are enzymes that in humans are encoded by the same TPSAB1 gene. [ 5 ] [ 6 ] Beta tryptases appear to be the main isoenzymes expressed in mast cells ; whereas in basophils , alpha tryptases predominate.
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.
More specifically, optimal levels are generally close to a central tendency of the values found in the population. However, usual and optimal levels may differ substantially, most notably among vitamins and blood lipids, so these tables give limits on both standard and optimal (or target) ranges.
