upptagstest
Upptagstest is a term used in biology and medicine to describe procedures that measure the uptake of a substance into cells, tissues, or whole organisms. The goal is to quantify how quickly and to what extent a substrate is internalized, which can reflect transporter activity, membrane permeability, and subsequent metabolic processing. The concept is applied across in vitro, ex vivo, and in vivo settings.
In vitro uptake assays are common, where cultured cells are exposed to a labeled substrate such as
Data from upptagstest are typically analyzed as uptake rate over time, maximal accumulation, and, in transporter
Applications span pharmacology, toxicology, physiology, and clinical diagnostics. They are used to characterize drug delivery and
