Thermo Fisher Scientific is requesting kUA /l to be represented as the standard unit for allergen specific IgE results.

When reporting results for an allergen-specific IgE antibody test, the notation should clearly indicate the result is a measurement of a subset of IgE antibodies and not total IgE immunoglobulin. By including a subscript “A” it is clear the result is for allergen-specific antibody. Measurements of both allergen-specific antibodies and total IgE immunoglobulin are concentrations and requires expressions of volume.

Specific IgE antibodies are expressed in (kUA/l) where A represents allergen-specific antibodies, and Total IgE values are expressed in kU/l

Hi Joanne,

Do you have any supporting documentation (e.g., journal articles) that you could point us to for additional information?

Requests for new UCUM codes are reviewed on a variable schedule with the UCUM committee. I will add this request to our next agenda.

Thank you,

Hello Joanne,

I had an opportunity to look a little further into this. It seems a similar (perhaps identical) question was posted to LOINC years ago.

Hope this is helpful.

Use the existing UCUM code k[AU]/l - see https://github.com/ucum-org/ucum/issues/180
