Its main advantages are that it is less invasive, reduces patient discomfort, and potentially can be performed without the direct supervision of a healthcare professional. These features could facilitate access to healthcare, particularly for patients with limited access to clinical facilities or those requiring frequent testing, thereby supporting telemedicine, and improving participation in screening programs and clinical trials. However, its integration into routine clinical practice requires the development of standardized traceable processes and user-friendly collection kits that preserve sample quality and have preanalytical error rates comparable to those of venipuncture. Compliance with ISO 15189 and integration into existing laboratory workflows are essential. Moreover, device affordability and compatibility with analyzers will determine accessibility and scalability. Addressing logistical, regulatory, and technical challenges is key to fully realizing its potential as a patient-centric solution in modern healthcare, where the robustness of analytical data derived from capillary blood could be comparable to that obtained from venous blood. In this review, we analyze the potential role of capillary blood in routine clinical practice, highlighting its benefits and challenges and determining the conditions necessary for its successful implementation.<\/jats:p>","DOI":"10.1515\/cclm-2025-0888","type":"journal-article","created":{"date-parts":[[2025,11,13]],"date-time":"2025-11-13T17:18:00Z","timestamp":1763054280000},"page":"752-766","source":"Crossref","is-referenced-by-count":6,"title":["Capillary blood in core laboratories: current and future challenges"],"prefix":"10.1515","volume":"64","author":[{"given":"\u00c1lvaro","family":"Gonz\u00e1lez","sequence":"first","affiliation":[{"name":"Service of Biochemistry , Cl\u00ednica Universidad de Navarra , Pamplona , Spain"},{"name":"IdiSNA, Navarra Institute for Health Research , Pamplona , Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sara","family":"Deza","sequence":"additional","affiliation":[{"name":"Service of Biochemistry , Cl\u00ednica Universidad de Navarra , Pamplona , Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julia","family":"Maroto-Garc\u00eda","sequence":"additional","affiliation":[{"name":"Service of Biochemistry , Cl\u00ednica Universidad de Navarra , Pamplona , Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nerea","family":"Varo","sequence":"additional","affiliation":[{"name":"Service of Biochemistry , Cl\u00ednica Universidad de Navarra , Pamplona , Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"374","published-online":{"date-parts":[[2025,11,14]]},"reference":[{"key":"2026051215045290914_j_cclm-2025-0888_ref_001","doi-asserted-by":"crossref","unstructured":"Rosenfeld, L.
