The decision around timing of the tests in the Anaphylaxis guideline was made by consensus, and so the GDG discussed whether the same view would be held by health professionals now. The GDG therefore considered the unit costs of these tests and discussed the likely impact on downstream resources and health related quality of life.

    Transfer 1 mL serum to an ARUP Standard Transport Tube. Samples should preferably be collected between 15 minutes and three hours after the event. Specimen Requirements Collection. Separate serum or plasma from cells and transfer to a plastic transport tube. Tryptase is the most abundant protein component of human mast cell secretory granules.1,2 Serum levels generally reflect the extent of mast cell activation either by IgE- or non-IgE-mediated mechanisms.
    This indicates that serum tryptase may remain elevated beyond 4 hours, but this study was not large enough to be conclusive.

    It is noted that this figure does not capture the full economic impact of tryptase testing, which would include the time of a healthcare professional to administer the tests, as well as downstream cost and quality of life implications of using the tests.

    The evidence indicated that the proportion of people who have the condition when they tested positive PPV was high. The group agreed that the test is currently underutilised within primary care, but needs to be undertaken in a timely manner and records of timings kept in the person's notes.

    The other studies all investigated reactions to anaesthesia and did not report any timings other than a 2-hour time point. The GDG therefore agreed that mast cell tryptase testing is likely to be cost effective. Do you like this?

This could reduce future hospitalisations due to further allergic reactions in those with drug allergy, thereby reducing costs and improving quality of life, and reducing excess spending on unnecessary alternative drugs in those without drug allergy.

    The GDG noted that the test was more likely to be done within a shorter time period in a hospital emergency setting, and that after 4 hours the patient may have been moved and so there may be an increased chance the test would not be undertaken at all and cases may be missed.
