Cell-free DNA of ovarian tumor origin can be detected in samples from the gynecologic tract. This study aims to evaluate how pre-analytical handling, and storage conditions affect DNA profile and integrity in Pap tests, to optimize its potential for detection of ovarian cancers (OC). Analysis of archived Pap tests from OC patients, kept at RT for 48h and stored at -80°C was complemented by in vitro experiments.

Liquid biopsy (LB) has revolutionized molecular pathology, offering non-invasive insights into tumor biology. However, widespread adoption is hindered by a lack of standardized protocols, requiring robust quality control and harmonized workflows. Large-scale studies are needed to establish effective standard operating procedures (SOPs), particularly for circulating tumor DNA (ctDNA) assays tailored to different disease stages.

As novel, anti-amyloid therapies have become more widely available, access to timely and accurate diagnosis has become integral to ensuring optimal treatment of patients with early-stage Alzheimer's disease (AD). Plasma biomarkers are a promising tool for identifying AD pathology; however, several technical and clinical factors need to be considered prior to their implementation in routine clinical use. Given the rapid pace of advancements in the field and the wide array of available biomarkers and tests, this review aims to summarize these considerations, evaluate available platforms, and discuss the steps needed to bring plasma biomarker testing to the clinic.

Metabolic profiling (untargeted metabolomics) aims for a global unbiased analysis of metabolites in a cell or biological system. It remains a highly useful research tool used across various analytical platforms. Incremental improvements across multiple steps in the analytical process may have large consequences for the end quality of the data.

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.
