Biomarkers
What are Biomarkers?
Biomarkers are measurable indicators of biological processes, conditions, or diseases. They can be molecules, genes, or proteins found in the body that reflect normal or abnormal physiological states. Biomarkers are used in medicine to diagnose diseases, monitor disease progression, predict health risks, and evaluate the effectiveness of treatments.
Why are Biomarkers important?
Biomarkers are important because they:
- Provide valuable information for diagnosing and tracking diseases, including cancer, cardiovascular conditions, and metabolic disorders.
- Help monitor the progression of diseases and the response to treatment, enabling more personalised and effective healthcare.
- Allow for early detection of health conditions, improving the chances of successful intervention and treatment.
Biomarkers play a crucial role in improving patient care, disease prevention, and health outcomes.
How do Biomarkers affect health?
Biomarkers affect health by:
- Diagnosing diseases: Biomarkers can identify the presence of diseases, such as cancer or heart disease, at an early stage, even before symptoms appear.
- Tracking disease progression: Biomarkers help doctors monitor how a disease is progressing, allowing for better treatment decisions.
- Guiding treatment: Certain biomarkers can indicate how well a treatment is working, leading to adjustments for better outcomes.
By providing insights into a person’s health status, biomarkers help guide medical decisions, improve outcomes, and prevent complications.
How are Biomarkers measured?
Biomarkers are typically measured using:
- Blood tests: Biomarkers are often detected in blood samples, where they can be used to assess various diseases, including infections, cancer, and metabolic disorders.
- Genetic tests: Biomarkers related to genetic mutations or predispositions can be identified through DNA analysis.
- Imaging tests: Some biomarkers can be assessed using imaging techniques, such as MRI or CT scans, to track disease progression or organ function.
These methods allow healthcare providers to gain critical insights into a patient's health and develop more personalised treatment plans.
