Medical diagnosis (abbreviated Dx or DS) is the process of determining which disease or condition explains a person's symptoms and signs.

It is most often referred to as diagnosis with the medical context being implicit.

The information required for diagnosis is typically collected from a history and physical examination of the person seeking medical care.

Often, one or more diagnostic procedures, such as diagnostic tests, are also done during the process.

Sometimes Posthumous diagnosis is considered a kind of medical diagnosis.

A disease is a particular abnormal condition, a disorder of a structure or function, that affects part or all of an organism.

The study of disease is called pathology which includes the study of cause.

Disease is often construed as a medical condition associated with specific symptoms and signs.

It may be caused by external factors such as pathogens, or it may be caused by internal dysfunctions particularly of the immune system such as an immunodeficiency, or a hypersensitivity including allergies and autoimmunity.

A symptom (from Greek σύμπτωμα, "accident, misfortune, that which befalls", from συμπίπτω, "I befall", from συν- "together, with" and πίπτω, "I fall") is a departure from normal function or feeling which is noticed by a patient, reflecting the presence of an unusual state, or of a disease.

A symptom is subjective, observed by the patient, and cannot be measured directly, whereas a sign is objectively observable by others.

For example, paresthesia is a symptom (only the person experiencing it can directly observe their own tingling feeling), whereas erythema is a sign (anyone can confirm that the skin is redder than usual).

Symptoms and signs are often nonspecific, but often combinations of them are at least suggestive of certain diagnoses, helping to narrow down what may be wrong.

In other cases they are specific even to the point of being pathognomonic.

Preventive healthcare (alternately preventive medicine or prophylaxis) consists of measures taken for disease prevention, as opposed to disease treatment.

Just as health encompasses a variety of physical and mental states, so do disease and disability, which are affected by environmental factors, genetic predisposition, disease agents, and lifestyle choices.

Health, disease, and disability are dynamic processes which begin before individuals realize they are affected.

Disease prevention relies on anticipatory actions that can be categorized as primal, primary, secondary, and tertiary prevention.

A medical test is a kind of medical procedure performed to detect, diagnose, or monitor diseases, disease processes, susceptibility, and determine a course of treatment.

It is related to clinical chemistry and molecular diagnostics, and the procedures are typically performed in a medical laboratory.
