BUN stands for blood urea nitrogen. Urea nitrogen is what forms when protein breaks down.A test can be done to measure the amount of urea nitrogen in the blood.Blood is drawn from a vein, usually from the inside of the elbow or the back of the hand.
|
|
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.

However, there is a narrow concentration limit of these electrolytes that the body must maintain within each of these compartments. The body transfers electrolytes intracellularly and extracellularly as required to maintain electrolyte balance.
|
|
Electrolytes are positively and negatively charged ions that are found within the cells and extracellular fluids, including blood plasma. A test for electrolytes includes the measurement of sodium, potassium, chloride, and bicarbonate.

Urinalysis is the physical, chemical, and microscopic examination of urine. It involves a number of tests to detect and measure various compounds that pass through the urine.A urine sample is needed.
|
|
Urinalysis is a diagnostic physical, chemical, and microscopic examination of a urine sample(specimen). Specimens can be obtained by normal emptying of the bladder(voiding) or by a hospital procedure called catheterization.
|
|
Urinalysis is an important test used in diagnosing diseases of the genitourinary tract. Urine is examined for pH and specific gravity by chemical and direct microscopic methods.
|
|
Urine typically contains epithelial cells shed from the urinary tract. Urine cytology evaluates this urinary sediment for the presence of cancerous cells from the lining of the urinary tract, and it is a convenient noninvasive technique for follow...

A biopsy is the removal of a small piece of tissue for laboratory examination.
|
|
A biopsy describes the procedure that is used to obtain a very small piece of the target tissue. For some tissues, like the lining of the cheek, cells can be obtained just by scrapping the tissue surface.

|
|
A biopsy is a small sample of tissue or fluid taken from the body. This sample can then be studied in a laboratory. Image-guided biopsy allows a sample to be taken from an abnormal mass without the need for surgery. This procedure is done by a specially trained doctor called an interventional radiologist.

|
Detailed information on biopsy and the biopsy report For many health problems, a diagnosis is made by removing a sample of tissue for study in the pathology laboratory. The biopsy report describes the findings of a specimen.
|
|
Most biopsies involve taking a small piece of skin or muscle under a local anesthetic. When the cells to be analyzed are accessible by needle, the biopsy specimen may be removed with a hollow aspiration needle, which is used to suck out the sample...
