Rheumatoid factor (RF) is a blood test that measures the amount of the RF antibody in the blood.
|
 |
The blood differential test measures the percentage of each type of white blood cell (WBC) that you have in your blood. It also reveals if there are any abnormal or immature cells. See also: Complete blood count (CBC; Eosinophil count - absolute.
|
 |
A white blood cell (WBC) count determines the concentration of white blood cells in the patient's blood. A differential determines the percentage of each of the five types of mature white blood cells.
|
|
The white blood cell count and differential determine the number of white blood cells and the percentage of each type of white blood cell in a person's blood. These tests are included in general health examinations and help investigate a variety o...

ESR stands for erythrocyte sedimentation rate. It is a test that indirectly measures how much inflammation is in the body. However, it rarely leads directly to a specific diagnosis.
|
|
The sedimentation rate test, also called the erythrocyte sedimentation rate (ESR) or sed rate test, measures the speed at which the red blood cells (erythrocytes or RBCs) separate from the liquid part of the blood (plasma) and settle to the bottom...
|
|
The erythrocyte sedimentation rate (ESR), or sedimentation rate (sed rate), is a measure of the settling of red blood cells in a tube of blood during one hour. The rate is an indication of inflammation and increases in many diseases.

The antinuclear antibody panel is a blood test that looks at antinuclear antibodies (ANA. Antinuclear antibodies are substances produced by the immune system that attack the body's own tissues. See also: Autoimmune disorder
|
|
The antinuclear antibody (ANA) test is a test done early in the evaluation of a person for autoimmune or rheumatic disease, particularly systemic lupus erythematosus (SLE).
|
|
C-reactive protein is produced by the liver. The level of CRP rises when there is inflammation throughout the body. This article discusses the blood test done to measures the amount of CRP in your blood.
|
|
Complement is a blood test that measures the activity of certain proteins in the liquid portion of your blood. The complement system is a group of proteins that move freely through your bloodstream. The proteins work with your immune system and pl...

A complete blood count (CBC) test measures the following: The number of red blood cells (RBCs; The number of white blood cells (WBCs; The total amount of hemoglobin in the blood; The fraction of the blood composed of red blood cells (hematocrit; T...

One of the most commonly ordered clinical laboratory tests, a blood count, also called a complete blood count (CBC), is a basic evaluation of the cells (red blood cells, white blood cells, and platelets) suspended in the liquid part of the blood (...
|
 |
A complete blood count (CBC) is a series of tests used to evaluate the composition and concentration of the cellular components of blood. It consists of the following tests: red blood cell (RBC) count, white blood cell (WBC) count, and platelet co...

Ultrasound involves the use of high-frequency sound waves to create images of organs and systems within the body.
|
|
Ultrasonography is a diagnostic technique that involves directing high frequency sound waves at tissues in the body to generate images of anatomical structures. Ultrasonography is also called sonography, diagnostic sonography, and echocardiography...

Diagnostic medical sonography, or ultrasound, is a technique using high frequency sound to create images of specific areas of the body to diagnose various pathologies. The diagnostic medical sonographer performs examinations, records anatomic cond...
|
|
The use of ultrasound to obtain diagnostic images is referred to as diagnostic sonography. Since diagnostic sonography utilizes a nonionizing form of energy, there are no known bioeffects. Thus, diagnostic sonography is applied to a large spectrum...
|
|
Ultrasonography is the study of internal organs or blood vessels using high-frequency sound waves. The actual test is called an ultrasound scan or sonogram. Duplex ultrasonography uses Doppler technology to study blood cells moving through major v...

A computed tomography (CT) scan is an imaging method that uses x-rays to create cross-sectional pictures of the body. See also: Cranial CT scan; Lumbosacral spine CT scan; Orbit CT scan; Thoracic CT scan.
|
 |
Computed tomography (also known as CT, CT scan, CAT, or computerized axial tomography) scans use x rays to produce precise cross-sectional images of anatomical structures.
|
 |
Computed tomography scanning, also called CT scan, CAT scan, or computerized axial tomography, is a diagnostic tool that provides views of internal body structures using x rays. In the field of mental health, a CT scan may be used when a patient s...
|
 |
Computed tomography (CT) scans are completed with the use of a 360-degree x-ray beam and computer production of images. These scans allow for cross-sectional views of body organs and tissues.
|
 |
Computed tomography (CT), formerly referred to as computerized axial tomography (CAT), is a common diagnostic imaging procedure that uses x rays to generate images (slices) of the anatomy.
|
 |
Computed tomography (CT) scanning is a valuable diagnostic tool that provides physicians with views of internal body structures. During a CT scan, multiple x rays are passed through the body, producing cross-sectional images, or "slices, " on a ca...
