Introduction: The limit of quantification (LOQ) is defined as the lowest analyte concentration that can be reproducibly measured with defined imprecision expressed as CV (coefficient of variation). Low concentrations of hormones estradiol, LH, FSH and testosterone are essential in diagnosis and monitoring of various endocrine disorders. Automated immunoassays have well known advantages, but still limited in achieving necessary analytical sensitivity. The major concern is to pr...

Introduction: Biological variation (BV) data describe the variability of clinically important measurands around homeostatic set points within subjects (CVI) and between subjects (CVG). The availability of well characterized data enables the interpretation of laboratory results in clinical settings and can also be used to define analytical performance specifications. The aim of this study was to deliver BV estimates for anti-Müllerian hormone (AMH) and androstenedione amon...

Aim: Functional neuroendocrine tumors (NETs) represent a specific diagnostic and therapeutic challenge. Hormonal clinical syndrome can severely complicate clinical picture and affect treatment. Functional pancreatic NETs have been extensively studied. Our aim was to analyze functional lung NETs in terms of clinical characteristics and survival.Materials and methods: We retrospectively analyzed data from 230 patients with lung NETs treated at our departme...

Introduction: Pancreatic neuroendocrine tumors (PNETs) are generally clinically more indolent than adenocarcinomas. But relevant, clinically applicable prognostic survival factors still need to be more precisely defined.Aim: To identify survival factors in patients with PNETs.Methods: We analyzed 66 patients with PNETs (52.62±13.3 years old) treated at our department during 2003–2010. Patients with insulinomas were not in...

Aim: Functional neuroendocrine tumors (NETs) represent a specific diagnostic and therapeutic challenge, since hormonal clinical syndrome can severely complicate clinical picture and affect treatment. Our aim was to analyze characteristics and survival of functional pancreatic NETs.Materials and methods: We retrospectively analyzed data from 272 patients with pancreatic NETs treated at our department from the year 2005 till 2023. The patients underwent st...
