GN proposal: NPU04133 Plasma—Iron; substance concentration(at saturation) = ? micromole per liter

Thera are two types of TIBC. In addition to the description above there is another TIBC which is a measured many laboratories, and proposed to be included in the NPU terminology NPU NPUXXXXX Plasma—Transferrin(Iron binding sites); substance concentration = ? micromole per litre)

GN: A distinction between Ratio and Relative kind of properties in the NPU terminology has been:
A ratio kind of property is the ratio between two components in the same system.
A relative kind of property is the ratio between the same property in two systems.

In relation to plural/singular we have the following concepts in the top 100 list:

NPU26879 Rtcs(B)—Haemoglobin; entitic mass = ? pg
NPU26880 Ercs(B)—Haemoglobin; entitic mass = ? pg
NPU21371 Lkcs(B)—HLA-B27 antigen; arb.num.(proc.) = ?

  1. Welcome @dkarlsson

  2. Meeting of the Terminology Standards WG in Antwerp @dkruse
    Dennis, Daniel, Keng-Ling will prepare a presentation, Keng-Ling to contact Karim

  3. Progress of mapping @pwilliams
    Fasting patient, blood cells have been addressed in Jira-tickets.

  4. Analysis of results @Majken
    POC finalised in 2025, analysis in Q1, ready for Vienna meeting

  5. Forums @dkarlsson
    Tested writing agenda and minutes in forums. Participants needs to register.

  6. Total iron binding capacity

    Represent NPU04133 Plasma—Iron; substance concentration(at saturation) = ? micromole per liter in the proof-of-concept

  7. Plural/singular

-

  1. Proc. In k-o-p

No representation of “proc.” in SNOMED concept, check that this does not cuase duplicates

  1. Ratio compnent

Dicsussion in the LTSWG about ratios and relative kinds-of-property. Compare the outcomes of that discussion.

Consider fractions as well.

  7. Plural/singular
    Blood cells, if meaning is a population of cells is in NPU denoted with plural form, e.g. Leukocytes. SNOMED CT has concepts for populations: 702948002 |Population of cells in portion of fluid (body structure)| and for single cells: <<63370004 |Blood cell (cell)|. LOINC has chose the single cell concepts, and for NPU purposes the single cell concepts would work as well.
