Summary of Diagnostic Test :-

A diagnostic test is a test used to identify a condition or its cause. It is used to diagnose. A diagnostic test performed as a part of a medical exam may be used to identify the cause of symptoms or identify a disease. When used for other purposes, a diagnostic test may be used to identify specific strengths and weaknesses.

Diagnostic tests may also be used to determine the cause of a behavior or characteristic. For instance, a student having difficulty reading may undergo diagnostic testing to determine if he or she has dyslexia or a visual impairment.

Workplace Testing Explains Diagnostic Test
A diagnostic test is usually designed to identify a particular condition or set of characteristics. For example, a test to diagnose diabetes would look for physical characteristics associated with diabetes (such as high glucose blood levels a specific time after ingesting a controlled amount of sugar). While a test for hearing damage would be quite different in nature and scope. Beyond medical testing, diagnostic tests can be used to identify equipment failures, learning or social disabilities, and software malfunctions.

Diagnostic tests differ from others test in that a diagnostic test is meant to identify or measure the presence of a particular factor. At their simplest, a diagnostic test can render a yes or no answer. Often diagnostic tests not related to human beings are called troubleshooting. It is a method of narrowing down and finding answers to a problem.

1. X-Rays
Radiography or X-ray uses radiation and radio waves to create images of the bones and organs. X-ray was the very first diagnostic imaging tool used and is still the most widely used non-invasive diagnostic procedure today. For broken bones and chest obstructions, X-rays are usually the first requested medical imaging procedure.

2. MRI

A highly advanced diagnostic imaging procedure that creates images of the inner structures of the body without the use of radiation is Magnetic Resonance Imaging (MRI). MRI uses a powerful magnet and radio waves to produce highly detailed images of what’s inside the body.

3. Ultrasound
An ultrasound uses sound waves, a transducer, and a computer to create images of the internal organs. It is most well-known as a tool used by obstetricians, but it has more applications than that. It is also used in treatment, particularly ultrasound-guided treatments for pain.

4. Mammography
Mammography is used as a screening and diagnostic tool for women to detect abnormal growths in the breast. With the digitization of mammography, radiation exposure is cut down to very low dosages.
