It is most often referred to as diagnosis with the medical context being implicit.
Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others.

Physical examination

physical exammedical examinationexamination
The information required for diagnosis is typically collected from a history and physical examination of the person seeking medical care.
Together, the medical history and the physical examination aids in determining the correct diagnosis and devising the treatment plan.

Differential diagnosis

differential diagnosesdifferentiateddifferential
Thus differential diagnosis, in which several possible explanations are compared and contrasted, must be performed.
Differential diagnostic procedures are used by physicians to diagnose the specific disease in a patient, or, at least, to eliminate any imminently life-threatening conditions.

A diagnostic procedure may be performed by various healthcare professionals such as a physician, physiotherapist, dentist, podiatrist, optometrist, nurse practitioner, healthcare scientist or physician assistant.
A physician, medical practitioner, medical doctor, or simply doctor, is a professional who practises medicine, which is concerned with promoting, maintaining, or restoring health through the study, diagnosis, prognosis and treatment of disease, injury, and other physical and mental impairments.

Physical therapy

A diagnostic procedure may be performed by various healthcare professionals such as a physician, physiotherapist, dentist, podiatrist, optometrist, nurse practitioner, healthcare scientist or physician assistant.
PTs use an individual's history and physical examination to arrive at a diagnosis and establish a management plan and, when necessary, incorporate the results of laboratory and imaging studies like X-rays, CT-scan, or MRI findings.

Magnetic resonance imaging

MRIMRI scanmagnetic resonance imaging (MRI)
This may occur as a result of an incidental finding of a sign unrelated to the parameter of interest, such as can occur in comprehensive tests such as radiological studies like magnetic resonance imaging or blood test panels that also include blood tests that are not relevant for the ongoing diagnosis.
MRI is widely used in hospitals and clinics for medical diagnosis, staging of disease and follow-up without exposing the body to radiation.


Traditional Chinese Medicine, as described in the Yellow Emperor's Inner Canon or Huangdi Neijing, specified four diagnostic methods: inspection, auscultation-olfaction, interrogation, and palpation.
Nonetheless, some things are not palpable, which is why additional medical tests, such as medical imaging and laboratory tests, are often needed to make a diagnosis.

Sensitivity and specificity

Diagnosis is often challenging, because many signs and symptoms are nonspecific.
In medical diagnosis, test sensitivity is the ability of a test to correctly identify those with the disease (true positive rate), whereas test specificity is the ability of the test to correctly identify those without the disease (true negative rate).

Medical test

Often, one or more diagnostic procedures, such as medical tests, are also done during the process.
A medical test is a medical procedure performed to detect, diagnose, or monitor diseases, disease processes, susceptibility, or to determine a course of treatment.


HippocraticHippocrates of CosHippocrates of Kos
Hippocrates was known to make diagnoses by tasting his patients' urine and smelling their sweat.
The Hippocratic school or Koan school achieved greater success by applying general diagnoses and passive treatments.

Doctor's visit

consultationconsultantConsultation (doctor)
Diagnosis is a major component of the procedure of a doctor's visit.
The physician then makes a review of systems (ROS) or systems inquiry, which is a set of ordered questions about each major body system in order: general (such as weight loss), endocrine, cardio-respiratory, etc. Next comes the actual physical examination and other medical tests; the findings are recorded, leading to a list of possible diagnoses.

Medical sign

Medical diagnosis (abbreviated Dx or D S ) is the process of determining which disease or condition explains a person's symptoms and signs.
Medical signs assist a healthcare provider to reach an accurate diagnosis.


BabyloniansBabylonianBabylonian Empire
A Babylonian medical textbook, the Diagnostic Handbook written by Esagil-kin-apli (fl.1069–1046 BC), introduced the use of empiricism, logic and rationality in the diagnosis of an illness or disease.
Along with contemporary ancient Egyptian medicine, the Babylonians introduced the concepts of diagnosis, prognosis, physical examination, and prescriptions.

Clinical decision support system

Clinical decision support systems are interactive computer programs designed to assist health professionals with decision-making tasks.
This means that clinicians interact with a CDSS to help to analyse, and reach a diagnosis based on, patient data.


Pathology is a significant field in modern medical diagnosis and medical research.

Prenatal testing

Prenatal diagnosis focuses on pursuing additional detailed information once a particular problem has been found, and can sometimes be more invasive.

Medical classification

A medical classification is used to transform descriptions of medical diagnoses or procedures into standardized statistical code in a process known as clinical coding.

Nursing diagnosis

Whereas a medical diagnosis identifies a disorder, a nursing diagnosis identifies the unique ways in which individuals respond to health and/or life processes and/or crises.

Medical error

This might include an inaccurate or incomplete diagnosis or treatment of a disease, injury, syndrome, behavior, infection, or other ailment.

Retrospective diagnosis

Sometimes posthumous diagnosis is considered a kind of medical diagnosis.
The term retrospective diagnosis is also sometimes used by a clinical pathologist to describe a medical diagnosis in a person made some time after the original illness has resolved or after death.


The tissue diagnosis from the biopsy indicates the type of cell that is proliferating, its histological grade, genetic abnormalities and other features.


It uses telecommunications technology to facilitate the transfer of image-rich pathology data between distant locations for the purposes of diagnosis, education, and research.

Diagnostic and Statistical Manual of Mental Disorders

A new "multiaxial" system attempted to yield a picture more amenable to a statistical population census, rather than a simple diagnosis.

Monitoring (medicine)

A treatment plan is proposed which may include therapy and follow-up consultations and tests to monitor the condition and the progress of the treatment, if needed, usually according to the medical guidelines provided by the medical field on the treatment of the particular illness.
The development of new techniques for monitoring is an advanced and developing field in smart medicine, biomedical-aided integrative medicine, alternative medicine, self-tailored preventive medicine and predictive medicine that emphasizes monitoring of comprehensive medical data of patients, people at risk and healthy people using advanced, smart, minimally invasive biomedical devices, biosensors, lab-on-a-chip (in the future nanomedicine devices like nanorobots) and advanced computerized medical diagnosis and early warning tools over a short clinical interview and drug prescription.
