Laboratory medicine impact on health inequalities

11.30am – 1pm BST, 11 June 2025 ‐ 1 hour 30 mins

Parallel session

This fascinating and thought provoking session, will focus on how aspects of laboratory medicine may in the past have added to healthcare inequalities, and how laboratory medicine can address these issues going forward.

The session will examine the impact our currently established reference ranges have on both transgender patients and minority ethnic groups of patients. Summarising the current situation, and presenting recent publications on the establishment of appropriate reference ranges.

By the end of this session, we hope that those that attend will foster a deeper understanding of the structural inequities within healthcare systems and how laboratory medicine can both highlight and contribute to the dispersion  of these disparities.

11.30  Laboratory social science: building diversity equity and inclusion into your laboratory - Karen Perkins
Diversity implies there is variation within a group. If variety is the spice of life, how can we flavour our daily work to better address the representation and intersectionality of human biodiversity? Let us explore diagnostic implications of issues such as race adjustment factors, reference interval applications and sex and gender differences in our local population.

Equity refers to the fair treatment of all people. Access is a component of equity. Let us explore how we, as clinical scientists can provide better access to our diagnostics by interrogating pre-analytical, analytical and post-analytical processes to reach the diverse members of our local community.

Inclusion involves the act of establishing policies, procedures and practices that ensure equitable access to our resources. Listening to patient voices about how, where and when they need access to our services builds a sense of belonging amongst our service users and purposefully cultivates engagement and innovation in the way we deliver laboratory medicine for the future.

We can focus effort in these three areas to remove health inequalities and make it become ‘business as usual’ not a separate issue, requiring special attention in our workspace.

12.00  Results from TransRIHTS: the trans & non-binary reference intervals while on hormone therapy study - Rue Ball
Laboratory test results are compared to reference intervals (RIs) to inform patients’ diagnosis and treatment. RIs for some tests may be affected by the hormone therapy taken by some transgender (trans) and non-binary people. However, to date there has been limited evidence establishing RIs in this population. Using an inappropriate RI increases the risk of delayed diagnosis or unnecessary further investigation. This compounds existing barriers to trans and non-binary peole accessing healthcare. To address this, the TransRIHTS study recruited a cross-sectional sample of 250 healthy trans and non-binary volunteers taking hormone therapy. Volunteers completed a questionnaire about their health and hormone therapy, and provided urine and blood samples. This is the largest study of RIs in healthy trans volunteers published to date. Separate RIs were calculated for people taking testosterone and oestradiol hormone therapy for 27 routine chemistry and immunoassay investigations. These include 13 tests with sex-based RIs: creatinine, liver enzymes, lipids, prolactin and ferritin. This talk will present the calculated RIs, compare them to cisgender RIs, and explore how they are affected by variation in hormone therapy. Recommendations will be made for how RIs should be reported for routine biochemistry tests in trans and non-binary service users.
