Laboratory policies and practices for thyroid function tests in Croatia: survey on behalf of Working Group for Laboratory Endocrinology of the Croatian Society of Medical Biochemistry and Laboratory Medicine

IntroductionLaboratory plays important part in screening, diagnosis, and management of thyroid disorders. The aim of this study was to estimate current laboratory preanalytical, analytical and postanalytical practices and policies in Croatia.Materials and methodsWorking Group for Laboratory Endocrinology of the Croatian Society of Medical Biochemistry and Laboratory Medicine designed a questionnaire with 27 questions and statements regarding practices and protocols in measuring thyroid function tests. The survey was sent to 111 medical biochemistry laboratories participating in external quality assurance scheme for thyroid hormones organized by Croatian Centre for Quality Assessment in Laboratory Medicine. Data is presented as absolute numbers and proportions.ResultsFifty-three participants returned the questionnaire. Response rate varied depending on question, yielding a total survey response rate of 46-48%. All respondents perform thyroid stimulating hormone (TSH). From all other thyroid tests, most performed is free thyroxine (37/53) and least TSH-stimulating immunoglobulin (1/53). Laboratories are using nine different immunoassay methods. One tenth of laboratories is verifying manufacturer’s declared limit of quantification for TSH and one third is verifying implemented reference intervals for all performed tests. Most of laboratories (91%) adopt the manufacturer’s reference interval for adult population. Reference intervals for TSH are reported with different percentiles (90, 95 or 99 percentiles).ConclusionThis survey showed current practices and policies in Croatian laboratories regarding thyroid testing. The results identified some critical spots and will serve as a foundation in creating national guidelines in order to harmonize laboratory procedures in thyroid testing in Croatia.

Intergroup resource allocation among children from minority and majority groups in three settings of former conflict

Intergroup resource allocation was examined among 333 children aged 7–11 (51.9% female) within three settings of former intergroup conflict (January–June 2021). Children represented both ethno-religious minority and majority groups (Republic of North Macedonia: Albanians, Macedonians; Croatia: Serbs, Croats; Northern Ireland: Catholics, Protestants), from predominantly White and middle-class families. Ingroup bias in average resource allocation amounts was demonstrated by both minority and majority children, across settings, in the context of novel targets (historic conflict rivals). Majority children were also more likely to give equally (which maintains the status quo) than minority children. Giving equally increased with age for both minority and majority children, despite being in “zero-sum,” conflict settings. Equitable intergroup resource allocation in such settings has implications for conflict transformation.
