Despite effective early treatment, FH remains underdiagnosed in children, highlighting the need for universal screening. This systematic review aims to evaluate the available evidence regarding suitable biomarkers for the purpose of universal screening for FH in childhood. The electronic databases Medline and Embase were systematically searched for studies comparing blood biomarkers in children with heterozygous FH and non-FH children. Of the 2,488 studies found, 35 were included. Although the data were constrained by considerable heterogeneity, LDL-c, total cholesterol (TC), and apolipoprotein B (ApoB) concentrations were consistently higher in children with FH across the included studies. Furthermore, increased non-high-density lipoprotein cholesterol (non-HDL-c), lathosterol, sitosterol and TC\/HDL-c ratio, and a decreased squalene\/TC ratio were found in children with FH. Only three screening studies combined biomarker (LDL-c, non-HDL-c and TC) and genetic testing simultaneously, revealing however limited sensitivity and specificity of these markers for FH screening in children. In this review, several biomarkers for FH screening in children were evaluated. As sensitivity and specificity data were generally not available or suboptimal, additional studies are needed to evaluate the screening performance of selected biomarkers in well-defined pediatric populations of suitable age and sex distribution, using valid analytical methods, and taking into account possible confounding factors. It is only through such studies that a well-considered selection of biomarkers can be made for the purpose of childhood screening for\u00a0FH.<\/jats:p>","DOI":"10.1515\/cclm-2026-0689","type":"journal-article","created":{"date-parts":[[2026,10,8]],"date-time":"2026-10-08T07:30:25Z","timestamp":1791444625000},"source":"Crossref","is-referenced-by-count":0,"title":["Towards a suitable biomarker for childhood screening for familial hypercholesterolemia: a systematic literature review"],"prefix":"10.1515","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7930-8275","authenticated-orcid":false,"given":"Vera H.","family":"de Kleijne","sequence":"first","affiliation":[{"name":"Endocrine Laboratory, Department of Laboratory Medicine , Amsterdam UMC , Amsterdam , The Netherlands"},{"name":"Amsterdam Gastroenterology Endocrinology & Metabolism Research Institute, Amsterdam UMC , Amsterdam , The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Barbara A.","family":"Hutten","sequence":"additional","affiliation":[{"name":"Amsterdam Gastroenterology Endocrinology & Metabolism Research Institute, Amsterdam UMC , Amsterdam , The Netherlands"},{"name":"Amsterdam Cardiovascular Sciences Research Institute, Diabetes & Metabolism, Amsterdam UMC , Amsterdam , The Netherlands"},{"name":"Department of Epidemiology and Data Science , Amsterdam UMC , Amsterdam , The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anita","family":"Boelen","sequence":"additional","affiliation":[{"name":"Endocrine Laboratory, Department of Laboratory Medicine , Amsterdam UMC , Amsterdam , The Netherlands"},{"name":"Amsterdam Gastroenterology Endocrinology & Metabolism Research Institute, Amsterdam UMC , Amsterdam , The Netherlands"},{"name":"Amsterdam Reproduction & Development Research Institute, Amsterdam UMC , Amsterdam , The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Annet M.","family":"Bosch","sequence":"additional","affiliation":[{"name":"Amsterdam Gastroenterology Endocrinology & Metabolism Research Institute, Amsterdam UMC , Amsterdam , The Netherlands"},{"name":"Amsterdam Reproduction & Development Research Institute, Amsterdam UMC , Amsterdam , The Netherlands"},{"name":"Department of Pediatrics, Division of Metabolic Diseases , Emma\u00a0Children\u2019s Hospital, Amsterdam UMC , Amsterdam , The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Willemijn E.","family":"Corpeleijn","sequence":"additional","affiliation":[{"name":"Amsterdam Gastroenterology Endocrinology & Metabolism Research Institute, Amsterdam UMC , Amsterdam , The Netherlands"},{"name":"Amsterdam Cardiovascular Sciences Research Institute, Diabetes & Metabolism, Amsterdam UMC , Amsterdam , The Netherlands"},{"name":"Department of Pediatrics, Division of Metabolic Diseases , Emma\u00a0Children\u2019s Hospital, Amsterdam UMC , Amsterdam , The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wendy P.J.","family":"den Elzen","sequence":"additional","affiliation":[{"name":"Amsterdam Gastroenterology Endocrinology & Metabolism Research Institute, Amsterdam UMC , Amsterdam , The Netherlands"},{"name":"Amsterdam Public Health Research Institute, Amsterdam UMC , Amsterdam , The Netherlands"},{"name":"Laboratory Specialized Diagnostics & Research, Department of Laboratory Medicine , Amsterdam UMC , Amsterdam , The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ren\u00e9","family":"Spijker","sequence":"additional","affiliation":[{"name":"Amsterdam Public Health, Medical Library, Amsterdam UMC , Amsterdam , The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Annemieke C.","family":"Heijboer","sequence":"additional","affiliation":[{"name":"Endocrine Laboratory, Department of Laboratory Medicine , Amsterdam UMC , Amsterdam , The Netherlands"},{"name":"Amsterdam Gastroenterology Endocrinology & Metabolism Research Institute, Amsterdam UMC , Amsterdam , The Netherlands"},{"name":"Amsterdam Reproduction & Development Research Institute, Amsterdam UMC , Amsterdam , The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2276-2589","authenticated-orcid":false,"given":"Monique","family":"Albersen","sequence":"additional","affiliation":[{"name":"Endocrine Laboratory, Department of Laboratory Medicine , Amsterdam UMC , Amsterdam , The Netherlands"},{"name":"Amsterdam Gastroenterology Endocrinology & Metabolism Research Institute, Amsterdam UMC , Amsterdam , The Netherlands"},{"name":"Amsterdam Public Health Research Institute, Amsterdam UMC , Amsterdam , The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"374","published-online":{"date-parts":[[2026,10,9]]},"reference":[{"key":"2026100807302041325_j_cclm-2026-0689_ref_001","doi-asserted-by":"crossref","unstructured":"Toft-Nielsen, F, Emanuelsson, F, Benn, M.
