blodbasert

Blodbasert is a Norwegian adjective meaning based on, or derived from, blood. In scientific and medical contexts the term is used to describe methods, analyses, or products that rely on blood samples or blood components, rather than on other biological materials such as urine, saliva, or tissue.

In diagnostics, blood-based approaches analyze components such as plasma, serum, red or white blood cells, platelets, or circulating molecules. They are used for infectious disease testing, monitoring of chronic diseases, and cancer biomarker assays. Examples include serology tests that detect antibodies, measurements of cholesterol and inflammatory markers in plasma, and detection of circulating tumor DNA or circulating tumor cells in blood.

In research and biotechnology, blood-based assays enable high-throughput screening, proteomic profiling, and pharmacokinetic studies. The term also appears in discussions of nutritional or physiological studies where blood markers are used to assess metabolic status, immune function, or response to treatment.

Limitations of blood-based methods include the need for venous blood draws, potential variability due to sampling conditions, and costs associated with laboratory analysis. Handling and storage requirements for blood samples can affect accuracy, and some conditions may require tissue-based or imaging approaches for definitive diagnosis. Overall, blodbasert describes approaches that derive information from blood as a source material.
