Urine: Urine analysis can reveal information about kidney function, metabolic disorders, and the presence of specific proteins or substances.
Tissue: Biopsy samples from organs or tissues can be analyzed for biomarkers associated with specific diseases, such as cancer cells or genetic mutations.
Other biological fluids: Saliva, cerebrospinal fluid, and even breath can be analyzed for biomarkers, depending on the specific health condition being assessed.

Types of Biomarkers

Biomarkers can be categorized based on their function and the information they provide:

Diagnostic biomarkers: These biomarkers help identify the presence of a specific disease. For example, the PSA test is a diagnostic biomarker for prostate cancer.
Prognostic biomarkers: These biomarkers provide information about the likely course of a disease, helping predict the risk of complications or the likelihood of response to treatment. For instance, certain biomarkers can indicate the aggressiveness of a tumor, guiding treatment decisions.
Predictive biomarkers: These biomarkers help determine an individual's likelihood of developing a particular disease. For example, genetic biomarkers can predict the risk of certain cancers or heart disease.
Monitoring biomarkers: These biomarkers help track the progression of a disease or the effectiveness of treatment. For example, blood sugar levels are monitored to manage diabetes, and tumor markers can track the response to cancer therapy.
