Fever may be the only symptom in some cases (the person has a fever of unknown origin. Signs of temporal arteritis may also be present. Blood tests are nonspecific. The sedimentation rate (ESR) is often elevated; Creatine kinase (CPK) is normal; H...

Symptoms are usually present for over a month by the time patients seek medical attention. A mild anemia is often present. One blood test, called an erythrocyte sedimentation rate, is very high, much more so than in most other diseases. The most i...

A CPK is a blood test that measures creatine phosphokinase (CPK), an enzyme found predominantly in the heart, brain, and skeletal muscle. When the total CPK level is substantially elevated, it usually indicates injury or stress to one or more of these areas.
|
|
The creatine kinase test measures the blood levels of certain muscle and brain enzyme proteins. Purpose Creatine kinase (CK or CPK) is an enzyme (a type of protein) found in muscle and brain.

ESR (erythrocyte sedimentation rate) is a nonspecific screening test for various diseases. This 1-hour test measures the distance (in millimeters) that red blood cells settle in unclotted blood toward the bottom of a specially marked test tube.
|
|
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 in a tube of anticoagulated blood. Purpose The sedimentation rate is a non-specific indicator of the presence of inflammation or infection .
|
|
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.

X-rays of the extremities (the hand, wrist, foot, and ankle) are images of internal structures. X-rays are a form of electromagnetic radiation like light, but of higher energy, so they can penetrate the body to form an image on film. Structures that are dense (such as bone) will appear white, air will be black, and other structures will be shades of gray. (See also bone x-ray .)

A hand x-ray is an examination involving images of one or both hands. X-rays are a form of electromagnetic radiation like light, but of higher energy, so they can penetrate the body to form an image on film. Structures that are dense (such as bone) will appear white, air will be black, and other structures will be shades of gray.

The hematocrit is the percent of whole blood that is composed of red blood cells. The hematocrit is a measure of both the number of red blood cells and the size of red blood cells. The hematocrit is almost always ordered as part of a complete blood count , which measures the number of red blood cells, the number of white blood cells, the total amount of hemoglobin in the blood, and the fraction of the blood composed of red blood cells (hematocrit).
|
|
Blood has a liquid component (plasma) and a particulate component (blood cells). The denser blood cells (most of which are red blood cells) will settle in a tube, particularly if the blood is spun in a device called a centrifuge.
|
|
The hematocrit measures how much space in the blood is occupied by red blood cells. It is useful when evaluating a person for anemia.

|
This test is an x-ray of a knee, shoulder, hip, wrist, ankle, or other joint.
