Blood gases measure the pH (acidity), oxygen content, and carbon dioxide content of the blood. Usually, blood gases are used to analyze the arterial blood. In rarer cases, venous blood may be used.

Blood gas analysis, also called arterial blood gas (ABG) analysis, is a procedure to measure the partial pressure of oxygen (O 2 ) and carbon dioxide (CO 2 ) gases and the pH (hydrogen ion concentration) in arterial blood. Purpose Blood gas analysis is used to diagnose and evaluate respiratory diseases and conditions that influence how effectively the lungs deliver oxygen to and eliminate carbon dioxide from the blood.

Blood gas analysis, also called arterial blood gas (ABG) analysis, is a test which measures the amounts of oxygen and carbon dioxide in the blood, as well as the acidity (pH) of the blood. Purpose An ABG analysis evaluates how effectively the lungs are delivering oxygen to the blood and how efficiently they are eliminating carbon dioxide from it.

Blood gases are defined as the mixture of gases, including oxygen (O 2 ), carbon dioxide (CO 2 ), and nitrogen (N 2 ), dissolved in the fluid fraction of blood. Oxygen from the air is transported from the lungs to all tissues of the body, where it is needed for metabolism ; and carbon dioxide, a by-product of metabolism, is taken from the tissues to the lungs to be eliminated.

Measurement of the pressure exerted by the circulating blood on the walls of the blood vessels , especially the arteries. Purpose The purpose of blood pressure measurement is to establish a baseline and detect any abnormalities from the normal state.
|
|
You can take your own blood pressure reading using a digital monitor.
|
|
Blood pressure measurement is the non-invasive measurement of the pressure exerted by the circulating blood on the walls of the body ' s arteries. Purpose The purpose of non-invasive blood pressure measurement is to detect any changes from normal values, which may indicate disease.

|
A discussion about the lower normal blood pressure reading and whether it is good for us.
|
|
A review of the methods and technology available for home monitoring, which can be an important aid to lowering your blood pressure.

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.

|
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)

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.
|
|
|
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.
|
|
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-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.
