Examples of biomarkers include everything from blood pressure and heart rate to basic metabolic studies and x-ray findings to complex histologic and genetic tests of blood and other tissues. Biomarkers are measurable and do not define how a person feels or functions.
What are the main biomarkers?
The three main classes are molecular biomarkers, cellular biomarkers or imaging biomarkers. All 3 types of biomarkers have a clinical role in narrowing or guiding treatment decisions and follow a sub-categorization of being either predictive, prognostic, or diagnostic.
What can biomarkers detect?
Biomarkers can help doctors and scientists diagnose diseases and health conditions, find health risks in a person, monitor responses to treatment, and see how a person’s disease or health condition changes over time. For example, an increased level of cholesterol in the blood is a biomarker for heart-attack risk.

What is a molecular biomarker?
Molecular biomarkers refer to non-imaging biomarkers that have biophysical properties, which allow their measurements in biological samples (e.g., plasma, serum, cerebrospinal fluid, bronchoalveolar lavage, biopsy) and include nucleic acids-based biomarkers such as gene mutations or polymorphisms and quantitative gene …
Is Haemoglobin a biomarker?
Hemoglobin, the protein that carries oxygen in blood, may be a promising biomarker to assess the clinical outcomes of patients with chronic obstructive pulmonary disease (COPD), a large U.S.-based study has found.
Are antibodies biomarkers?
Antibodies make suitable biomarkers for the prediction of disease because they are relatively easily measured in bodily fluids by a variety of (usually inexpensive) immunoassays. Biomarkers—whether antibodies or otherwise—can have 3 distinct roles in medicine.
