Hemostasis has been described as "a process by which the body spontaneously stops bleeding and maintains blood in the fluid state within the vascular compartment." There are at least four major systems that are involved in this complex process: the vasculature system, the platelets, the fibrin-forming system, and the fibrin- lysing system.

|
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.

A complete blood count (CBC) test measures the following: The number of red blood cells (RBCs; The number of white blood cells (WBCs; The total amount of hemoglobin in the blood; The fraction of the blood composed of red blood cells (hematocrit; The mean corpuscular volume (MCV) - the size of the red blood cells. CBC also includes information about the red blood cells that is calculated from the other measurements: MCH (mean corpuscular hemoglobin; MCHC (mean corpuscular hemoglobin concentration.
The platelet count is also usually included in the CBC.

One of the most commonly ordered clinical laboratory tests, a blood count, also called a complete blood count (CBC), is a basic evaluation of the cells (red blood cells, white blood cells, and platelets) suspended in the liquid part of the blood (plasma). It involves determining the numbers, concentrations, and conditions of the different types of blood cells.
|
|
|
A complete blood count (CBC) is a series of tests used to evaluate the composition and concentration of the cellular components of blood. It consists of the following tests: red blood cell (RBC) count, white blood cell (WBC) count, and platelet count; measurement of hemoglobin and mean red cell volume; classification of white blood cells (WBC differential); and calculation of hematocrit and red blood cell indices .
|
|
The clinical laboratory test that evaluates the three main cellular components of peripheral blood (red cells, white cells, and platelets) is called the " complete blood count " (CBC). It is used commonly to assess whether a patient is anemic (low red cell count), has an infection (increased white blood cells), or has abnormal blood coagulation (platelet levels).

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.

Electrolytes are positively and negatively charged molecules, called ions, that are found within cells, between cells, in the bloodstream, and in other fluids throughout the body. Electrolytes with a positive charge include sodium, potassium, calcium, and magnesium; the negative ions are chloride, bicarbonate, and phosphate.
|
|
Electrolytes are positively or negatively charged particles that readily dissolve in water. The predominant positively charged electrolytes in the body are sodium, potassium, calcium , and magnesium, while negatively charged electrolytes include chloride, phosphates, and bicarbonate.

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.

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.

An intravenous pyelogram (IVP) is a type of x-ray examination specifically designed to study the kidneys, bladder, and ureters (the tubes which carry urine from the kidneys to the bladder. After iodine-based contrast dye is injected into a vein, a series of images are taken at timed intervals. The kidneys are responsible for removing contrast dye from the blood and collecting it in urine. Abnormalities in the appearance of the kidneys or ureters, abnormalities in the distribution of contrast within a kidney, unequal amounts of dye in each kidney, or abnormalities in the collecting systems can be identified. These all suggest particular diseases and conditions.
|
|
Intravenous urography is a radiographic study of the urinary system using an intravenous contrast agent (dye). Of the many ways to obtain images of the urinary system, the intravenous injection of a contrast agent has been traditionally considered the best, although other modalities, such as computed tomography (CT) or ultrasound, are better for some disease processes.

|
Intravenous urography is a test that x rays the urinary system using intravenous dye for diagnostic purposes. The kidneys excrete the dye into the urine.

A renal biopsy is the removal of a small piece of kidney tissue for laboratory examination.

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.

Kidney function tests are common procedures used to evaluate renal function. Refer to the following documents for details of how each test is performed: Creatinine; Creatinine - urine; Creatinine clearance; BUN.
|
|
Kidney function tests are a cadre of tests that are used to screen for and manage renal disease. Tests commonly used for this purpose are plasma creatinine, blood urea nitrogen (BUN), electrolytes, and routine urinalysis .
|
|
Kidney function tests is a collective term for a variety of individual tests and procedures that can be done to evaluate how well the kidneys are functioning. A doctor who orders kidney function tests and uses the results to assess the functioning of the kidneys is called a nephrologist.

Kidney function tests is a collective term for a variety of individual tests and procedures that can be done to evaluate how well the kidneys are functioning. Purpose The kidneys, the body ' s natural filtration system, perform many vital functions, including removing metabolic waste products from the bloodstream, regulating the body ' s water balance, and maintaining the pH (acidity/alkalinity) of the body ' s fluids.

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, blood, bilirubin, nitrite, urobilinogen, and leukocyte esterase.

The urine specimen collection is a procedure used to obtain a sample of urine from a patient for diagnostic tests. Purpose The purpose of obtaining a urine sample is to test for any abnormalities that may be present, such as bacteria , ketones, or drugs.
|
|
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-up analysis of patients treated for urinary tract cancers.

Catecholamines are small molecules made by nerve tissue (including the brain) and the adrenal gland. The major catecholamines are dopamine, norepinephrine, and epinephrine. These substances break down into other compounds, which leave your body through your urine. A urine test can be done to measure the level of catecholamines in your body. Catecholamines can also be measured with a blood test. See: Catecholamines - blood
