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. Other samples are collected using forceps ...

|
A medical procedure used to diagnose a condition. 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 aspir...

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.
|
|
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. Urea then circulates in the blood in the form of urea nit...
