  Disclosed herein are methods of identifying biomarkers (such as genes (e.g., RNA or mRNA), proteins, and/or small molecules) that can be used to predict organ or tissue function or dysfunction. In some embodiments, the methods include ex vivo perfusion of the organ or tissue, collection of samples from the organ or tissue (for example, perfusate, fluids produced by the organ (such as bile or urine), or tissue biopsies) and measuring the level of one or more biomarkers in the sample. It is also disclosed herein that an analysis of biomarkers (such as genes (e.g., RNA or mRNA), proteins, and/or small molecules) present in a biological sample from an organ, tissue, or subject can be used to identify whether the organ, tissue, or subject is at risk for (or has) organ dysfunction or organ failure.

  本文公开了鉴定可用于预测器官或组织功能或功能障碍的生物标记物（如基因（如 RNA 或 mRNA）、蛋白质和/或小分子）的方法。在一些实施方案中，这些方法包括对器官或组织进行体外灌注，收集器官或组织的样本（例如灌注液、器官产生的液体（如胆汁或尿液）或组织活检），并测量样本中一种或多种生物标记物的水平。本文还公开了对来自器官、组织或受试者的生物样本中存在的生物标记物（如基因（如 RNA 或 mRNA）、蛋白质和/或小分子）的分析，可用于确定器官、组织或受试者是否有器官功能障碍或器官衰竭的风险（或已出现器官功能障碍或器官衰竭）。

  A method of assessing the quality of a biological sample while maintaining the viability of the biological sample for intended use analysis is described herein. The method includes analyzing a biological sample obtained from a subject for an intended use, assessing the quality of the biological sample using one or more biomarkers of sample quality, and simultaneously performing intended use analysis on the same sample. Assessing the quality of the sample can include assessing compliance with sample handling protocols and assessing subject compliance.

  本文描述了一种评估生物样本质量的方法，同时保持生物样本的活力，以便进行预期用途分析。该方法包括分析从受试者处获得的用于预期用途的生物样本，使用一个或多个样本质量生物标志物评估生物样本的质量，并同时对同一样本进行预期用途分析。评估样本质量可包括评估样本处理协议的合规性和评估受试者的合规性。
