BUN (blood urea nitrogen) is a test that measures the amount of urea nitrogen (a breakdown product of protein metabolism ) in the blood.
|
|
The blood urea nitrogen (BUN) test measures the level of urea nitrogen in a sample of the patient ' s blood. Urea is a substance that is formed in the liver when the body breaks down protein.

A bone scan is a test that detects areas of increased or decreased bone metabolism (turnover). The test is performed to identify abnormal processes involving the bone such as tumor, infection, or fracture.
|
|
A bone scan is a diagnostic imaging procedure used to evaluate abnormalities involving bones and joints. A radionuclide is injected intravenously, and its distribution in the skeletal system is analyzed to detect certain diseases or conditions.
|
|
A bone scan is an imaging test that uses a special camera to form images of your bones. It is used to diagnose bone problems, such as fractures, cancer, or infections, and joint problems such as arthritis. It is also used to check joint replacements.

|
A chest x ray is a procedure used to evaluate organs and structures within the chest for symptoms of disease. Chest x rays include views of the lungs, heart, small portions of the gastrointestinal tract, thyroid gland and the bones of the chest area.

The creatinine clearance test compares the level of creatinine in urine with the creatinine level in the blood, usually based on measurements of a 24-hour urine sample and a blood sample drawn at the end of the 24-hour period. Clearance is often measured as milliliters/minute (ml/min). Because creatinine is found in stable plasma concentrations, is freely filtered and not reabsorbed, and is minimally secreted by the kidneys, creatinine clearance is used to estimate the glomerular filtration rate (GFR) -- the standard by which kidney function is assessed.

An electrocardiogram (ECG) is a test that records the electrical activity of the heart. ECG is used to measure the rate and regularity of heartbeats as well as the size and position of the chambers, the presence of any damage to the heart, and the effects of drugs or devices used to regulate the heart (such as a pacemaker). See also stress test and Holter monitor (24h) .
|
|
The electrocardiogram (ECG) displays important information about the heart, including the occurrence of a heart attack or lack of oxygen, whether conduction of the heartbeat is disturbed, or its rate or rhythm altered. It is useful as a rapid indicator of the diagnosis and it is easy, painless, and inexpensive to record.

Detailed information on electrocardiogram, including how the EKG/ECG is performed and what happens after the procedure
|
|
Electrocardiography is a commonly used, noninvasive procedure for recording electrical changes in the heart. The record, which is called an electrocardiogram (ECG or EKG), shows the series of waves that relate to the electrical impulses that occur during each beat of the heart.
|
|
Did you know that electrical currents flow throughout your body? Because the strongest of these travels through your heart, doctors are able to monitor your heart by placing electrical sensors on the surface of your skin. They do this by giving you an electrocardiogram -- abbreviated either ECG or EKG (from the original German spelling of the word).
|
|
The ECG (also known as EKG) is a test that records electrical signals from your heart onto a paper strip. The pattern of these signals can tell the doctor whether your heart is normal, under stress, or experiencing electrical problems, strain, or damage.

During a physical examination, a health care provider studies a patient's body to determine the presence or absence of physical problems. A typical physical examination includes: Inspection (looking at the body) Palpation (feeling the body with hands) Auscultation (listening to sounds) Percussion (producing sounds)

A renal biopsy is a way to obtain a sample of kidney tissue. The sample is then examined in the laboratory.
|
|
Kidney biopsy is a medical procedure in which a small piece of tissue is removed from the kidney for microscopic examination. Purpose The test is usually done to diagnose kidney disease and to evaluate the extent of damage to the kidney.
