Background: Except host and environmental factors influencing individual human cytokine responses, pre-analytical handling procedures and detection methods also affect cytokine levels.
Methods: In this study, we used cytometric bead array (CBA) and chemiluminescence (ECL). These two methods were used to test serum and plasma samples from 50 healthy adult volunteers and 50 rheumatoid arthritis (RA) patients' cytokine levels.

Objectives: Careful consideration of the pre-analytical process for urine examination is essential to avoid errors and support accurate results and decision-making. Our objective was to assess the impact of various pre-analytical factors on urine test strip and quantitative chemistry results, including stability, tube type, fill volume, and centrifugation.
Methods: Residual random urine specimens were identified.
Development and validation of an LC-MS/MS method for quantification of Osimertinib and its two metabolites AZ7550 and AZ5104 in human plasma including long-time storage.

Osimertinib (AZD9291) is a widely used tyrosine kinase inhibitor for the treatment of non-small cell lung cancer patients with activating EGFR mutations. However, the correlation between dose and efficacy has been debated for several years. For this reason, there is a need for standardized methods for routine analysis, clinical studies on pharmacokinetics and dose-response relationships, and greater understanding of preanalytical conditions, such as sample storage stability.

Thyroglobulin (Tg) is a reliable marker for detecting recurrence in differentiated thyroid cancer (DTC) patients, but frequently occurring Tg antibodies (TgAbs) can hinder accurate measurement. We aimed to develop a preanalytical protocol for precise Tg detection in TgAb presence using the immunoradiometric assay (IRMA) platform. This study involved forty-five patients who underwent IRMA Tg and radioimmunoassay (RIA) TgAb measurements, including two patients monitored for recurrence and one with confirmed recurrence.

Background: Self-sampling is now a key component within HPV-based cervical screening programmes to engage individuals and enhance participation. As self-sampling is relatively new, information on the influence of pre-analytical parameters such as transit-temperature and time between sampling and testing on HPV test results requires detailed investigation.
Methods: FLOQSwabs® and Evalyn Brushes® were used to assess HPV and cellular stability over a 30-week period (0w,4w,12w,30w) at 4 °C, ambient, and 37 °C.
