Surrogate nutrition markers are used to assess adequacy of nourishment and to define malnutrition despite evidence that fails to link nourishment, surrogate markers, and outcomes. Markers such as serum levels of albumin, prealbumin, transferrin, and IGF-1 and delayed hypersensitivity and total lymphocyte count may be valid to help stratify risk. However, it is not appropriate to consider these as markers of adequacy of nourishment in the sick patient.
替代营养指标用于评估营养状况是否充足以及定义营养不良，尽管有证据表明营养、替代指标和结果之间并无关联。诸如血清白蛋白、前白蛋白、转铁蛋白和胰岛素样生长因子-1水平以及迟发型超敏反应和淋巴细胞总数等指标可能有助于分层风险。然而，将这些指标视为患病患者营养充足的标志并不恰当。
