The physical examination may show an enlarged liver (hepatomegaly) and general swelling. Tests may include: Urinalysis; Serum creatinine; Creatinine clearance; BUN; Serum potassium; Arterial blood gas; Total protein levels; CBC (complete blood cou...

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 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.

A nutrition assessment is an in-depth evaluation of both objective and subjective data related to an individual ' s food and nutrient intake, lifestyle, and medical history. Once the data on an individual is collected and organized, the practitioner can assess and evaluate the nutritional status of that person.
|
|
A dietary assessment is a comprehensive evaluation of a person ' s food intake. It is one of four parts of a nutrition assessment done in a clinical setting.

This is a test that measures the total amount of protein in serum (serum is the fluid portion of blood, without fibrinogen ).
|
|
Plasma protein tests are laboratory tests used to evaluate the levels of specific proteins in the blood. A decrease or increase in the concentration of the protein is associated with one or more clinical conditions.
|
|
|
Proteins are compounds composed of carbon, hydrogen, oxygen , and nitrogen , which are arranged as strands of amino acids . They play an essential role in the cellular maintenance, growth, and functioning of the human body.

Creatinine is a breakdown product of creatine, which is an important part of muscle. A serum creatinine test measures the amount of creatinine in the blood.
|
|
Creatine is an important compound produced by the body. It combines with phosphorus to make a high-energy phosphate compound in the body.

Urinalysis is a physical and/or chemical examination of the urine. It consist of a battery of chemical and microscopic tests to screen for urinary tract infections , renal (kidney) disease , and diseases of other organs that result in the appearance of abnormal metabolites (break-down products) in 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.
|
|
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. Purpose The purpose of obtaining a urine sample is to test for any abnormalities that may be present, such as bacteria , ketones, or drugs.
|
|
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.

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.
|
|
A urine dipstick is a colorimetric chemical assay that can be used to determine the pH, specific gravity, protein, glucose, ketone, bilirubin, urobilinogen, blood, leukocyte, and nitrite levels of an individual ' s urine. It consists of a reagent stick-pad, which is immersed in a fresh urine specimen and then withdrawn.
