Od 15.1.2024 rozšíříme poskytované hodnoty referenčních mezí u stanovení CTx – β a P1NP i pro dětskou populaci a pro mladistvé. Referenční hodnoty jsme převzali z článku Reference intervals for plasma β-CTX and P1NP in children: A systematic review and pooled estimates, z Clinical Biochemistry 118 (2023).
