We retrospectively reviewed all serial prolactin sampling performed during a 3\u2010year period. Patients with possible medication\u2010induced hyperprolactinaemia and macroprolactin interference were excluded. We assessed the effect of venepuncture\u2010associated stress on hyperprolactinaemia with the main outcome being normalisation of serum prolactin at the end of serial sampling.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Ninety\u2010three patients with documented hyperprolactinaemia (range 360\u20131690 mU\/L) were included in the analysis. Prolactin decreased during serial sampling in 73 patients (78%), suggesting a prevalent effect of venepuncture stress. The final prolactin sample was normal in 50 patients (54%), consistent with stress hyperprolactinaemia rather than pathological hyperprolactinaemia. Patients with a referral prolactin result greater than two times the upper reference limit (URL) were less likely (15%) to have a normal prolactin result on serial sampling. Measurement of a single rested prolactin sample from an indwelling cannula showed the same diagnostic utility as serial sampling.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Serum prolactin results are frequently elevated by the stress of venepuncture. Confirmation of pathological hyperprolactinaemia in a rested sample obtained from an indwelling venous cannula is recommended in patients with mild hyperprolactinaemia, particularly when the referral prolactin is less than two times the URL.<\/jats:p><\/jats:sec>","DOI":"10.1111\/imj.16208","type":"journal-article","created":{"date-parts":[[2023,8,22]],"date-time":"2023-08-22T09:14:52Z","timestamp":1692695692000},"page":"307-311","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["The utility of rested prolactin sampling in the evaluation of hyperprolactinaemia"],"prefix":"10.1111","volume":"54","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9025-3778","authenticated-orcid":false,"given":"Tom","family":"Wilkinson","sequence":"first","affiliation":[{"name":"Department of Endocrinology Christchurch Hospital, Te Whatu Ora Health New Zealand  Christchurch New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bobby","family":"Li","sequence":"additional","affiliation":[{"name":"Canterbury Health Laboratories  Christchurch New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steven","family":"Soule","sequence":"additional","affiliation":[{"name":"Department of Endocrinology Christchurch Hospital, Te Whatu Ora Health New Zealand  Christchurch New Zealand"},{"name":"Department of Medicine University of Otago (Christchurch)  Christchurch New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Penny","family":"Hunt","sequence":"additional","affiliation":[{"name":"Department of Endocrinology Christchurch Hospital, Te Whatu Ora Health New Zealand  Christchurch New Zealand"},{"name":"Department of Medicine University of Otago (Christchurch)  Christchurch New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,8,22]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1210\/jc.2009-0177"},{"key":"e_1_2_6_3_1","first-page":"575","article-title":"Diagnosis and management of hyperprolactinaemia","volume":"169","author":"Serri O","year":"2003","journal-title":"Can Med Assoc J"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1210\/jc.2010-1692"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1210\/jcem-72-2-287"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11102-014-0576-7"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1177\/11795514211025276"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/ajo.13416"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.4158\/EP-2020-0260"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1097\/j.pbj.0000000000000133"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.endinu.2019.11.006"},{"key":"e_1_2_6_12_1","first-page":"205","article-title":"Diagnosis of stress\u2010related hyperprolactinemia.
