|
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.
|
 |
Uric acid is a chemical created when the body breaks down substances called purines. Purines are found in some foods and drinks, such as liver, anchovies, mackerel, dried beans and peas, beer, and wine. Most uric acid dissolves in blood and travel...

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.

The osmolality urine test the concentration of particles in urine. Osmolality (particles/kg water) and osmolarity (particles/liter of solution) are sometimes confused, but for dilute fluids such as urine they are essentially the same. A blood test...

The sodium urine test measures the amount of salt (sodium) in a urine sample. Sodium can also be measured in a blood sample. See also: Sodium - blood test

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.
|
|
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.
|
|
A urinalysis is a group of manual and/or automated qualitative and semi-quantitative tests performed on a urine sample. A routine urinalysis usually includes the following tests: color, transparency, specific gravity, pH, protein, glucose, ketones...

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.
|
|
The urine specimen collection is a procedure used to obtain a sample of urine from a patient for diagnostic tests.The purpose of obtaining a urine sample is to test for any abnormalities that may be present, such as bacteria, ketones, or drugs.The...

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.

Detailed information on several of the different divisions of anatomical pathology, including biopsy, surgical pathology, cytology, and autopsy
|
|
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.

What type of biopsy will I have? Why do I need a biopsy? How long will it take?
|
|
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...
