Disease indicators, also known as disease markers or diagnostic markers, are measurable biological substances or characteristics that provide evidence of a particular disease or infection. These indicators can be detected in blood, urine, tissues, or other bodily fluids. They play a crucial role in the diagnosis, prognosis, and monitoring of diseases.

There are several categories of disease indicators. Biomarkers, a common type, can include proteins, enzymes, nucleic acids (DNA/RNA), or metabolites whose levels change in the presence of disease. For example, elevated levels of certain enzymes in the blood can indicate liver damage, while specific antibodies in the blood can signal an autoimmune disorder or an infection.

Another category includes imaging findings, where visual evidence from techniques like X-rays, CT scans, MRIs, or ultrasounds reveals abnormalities associated with a disease. Pathological indicators involve the microscopic examination of tissue samples (biopsies) to identify abnormal cells or structures characteristic of a disease, such as cancerous cells.

Clinical indicators are observable signs and symptoms reported by patients or detected during a physical examination, such as fever, pain, or a rash. Genetic indicators are inherited predispositions or mutations that increase an individual's risk of developing certain diseases.

The accurate identification and measurement of disease indicators require reliable laboratory tests and diagnostic procedures. These indicators help healthcare professionals make informed decisions about patient care, treatment strategies, and the prediction of disease progression.
