Medical biomarkers fall into 5 major categories: 1) diagnostic (used to identify if you have a disease or condition); 2) prognostic (used to determine how well you will do with the disease or condition); 3) predictive (used to determine if you may get the disease); 4) efficacy or monitoring (used to determine how well a drug or treatment is ...
An imaging biomarker is a biologic feature, or biomarker detectable in an image. [1] In medicine, an imaging biomarker is a feature of an image relevant to a patient's diagnosis. For example, a number of biomarkers are frequently used to determine risk of lung cancer.
Validation is a requirement of food, drug and pharmaceutical regulating agencies such as the US FDA and their good manufacturing practices guidelines. Since a wide variety of procedures, processes, and activities need to be validated, the field of validation is divided into a number of subsections including the following:
For instance, a regulatory agency (such as CE or FDA) may ensure that a product has been validated for general use before approval. An individual laboratory that introduces such an approved medical device may then not need to perform their own validation, but generally still need to perform verification to ensure that the device works correctly ...
In medicine, a biomarker is a measurable indicator of the severity or presence of some disease state. It may be defined as a "cellular, biochemical or molecular alteration in cells, tissues or fluids that can be measured and evaluated to indicate normal biological processes, pathogenic processes, or pharmacological responses to a therapeutic intervention."
More than 60,000 scientists from academia and industry use Genevestigator for their work in molecular biology, toxicogenomics, biomarker discovery and target validation. The original scientific publication has been cited over 3,500 times. The analysis tools are divided into three major sets:
In biomedical contexts, a biomarker, or biological marker, is a measurable indicator of some biological state or condition. Biomarkers are often measured and evaluated using blood, urine, or soft tissues [1] to examine normal biological processes, pathogenic processes, or pharmacologic responses to a therapeutic intervention.

The Bureau was transferred from the NIH to the FDA in 1972, where it was renamed Bureau of Biologics and focused on vaccines, serums for allergy shots, and blood products. [8] Ten years later, with the beginning of the biotechnology revolution, the line between a drug and a biologic, or a device and a biologic, became blurred. [8]
