Blood urea test

An electrolyte panel is a blood test to measure electrolytes (minerals) in blood. An electrolyte imbalance may be a sign of a heart, lung or kidney problem. Dehydration also causes electrolyte imbalances. Your provider may order an anion gap test along with the electrolyte panel to determine why certain electrolyte levels are too high or low. Overview What is an electrolyte panel (electrolyte blood test)? An electrolyte panel is a blood test that measures the levels of seven electrolytes in your blood. Certain conditions, including dehydration, cardiovascular disease and kidney disease, can cause electrolyte levels to become too high or low. This is an electrolyte imbalance. Other names for an electrolyte panel test include: • Electrolyte blood test. • Electrolyte lab test. • Serum electrolyte test. What are electrolytes? Electrolytes are minerals found in blood, tissue, urine and other body fluids. You also get electrolytes from foods, drinks and supplements. Electrolytes get their name because they give off an electrical charge when they dissolve in body fluids. Electrolytes play a critical role in: • Balancing fluids in your body. • Controlling your • Promoting bone and dental health. • Supporting nerve and muscle function. • Stabilizing What is the purpose of an electrolyte panel? You may get an electrolyte panel as part of a routine An electrolyte panel can detect electrolyte imbalances caused by: • • • • • Cardiovascular disease, • • Liver disease like • Overhydratio...

Collection Container/Tube: Preferred: Serum gel Acceptable: Red top Submission Container/Tube: Plastic vial Specimen Volume: 0.5 mL Collection Instructions: 1. Serum gel tubes should be centrifuged within 2 hours of collection. 2. Red-top tubes should be centrifuged, and the serum aliquoted into a plastic vial within 2 hours of collection. Urea is the final degradation product of protein and amino acid metabolism. In protein catabolism, the proteins are broken down to amino acids and deaminated. The ammonia formed in this process is synthesized to urea in the liver. This is the most important catabolic pathway for eliminating excess nitrogen in the human body. Increased blood urea nitrogen (BUN) may be due to prerenal causes (cardiac decompensation, water depletion due to decreased intake and excessive loss, increased protein catabolism, and high protein diet), renal causes (acute glomerulonephritis, chronic nephritis, polycystic kidney disease, nephrosclerosis, and tubular necrosis), and postrenal causes (eg, all types of obstruction of the urinary tract, such as stones, enlarged prostate gland, tumors). The determination of serum BUN currently is the most widely used screening test for the evaluation of kidney function. The test is frequently requested along with the serum creatinine test since simultaneous determination of these 2 compounds appears to aid in the differential diagnosis of prerenal, renal and postrenal hyperuremia. This kinetic ultraviolet assay utilizes ...

A high uric acid level can be the result of the body making too much uric acid, not getting rid of enough of it or both. Causes of a high uric acid level in the blood include: • • Drinking too much alcohol • Drinking too much soda or eating too much of foods that contain fructose, a type of sugar • Genetics also known as inherited traits • • Immune-suppressing drugs • Kidney problems • • • Niacin, also called vitamin B-3 • • • • A purine-rich diet, high in foods such as liver, game meat, anchovies and sardines • Tumor lysis syndrome — a rapid release of cells into the blood caused by certain cancers or by chemotherapy for those cancers People having chemotherapy or radiation treatment for cancer might be monitored for high uric acid levels. • Uric acid.

A BUN test measures the level of urea nitrogen in the blood using a standard blood sample. BUN stands for blood urea nitrogen, which is a natural byproduct of the breakdown of protein. According to the American Association for Clinical Chemistry, doctors perform BUN tests to assess kidney health. However, altered BUN counts can result from Due to the variety of conditions a BUN test can indicate, a doctor may recommend a BUN test as part of routine check-ups. BUN tests are part of standard blood tests, such as metabolic panels. Share on Pinterest BUN levels can provide an update on kidney and liver health. Healthcare professionals use BUN tests for a variety of reasons, including monitoring kidney and liver function. The liver and kidneys influence BUN levels profoundly, as they are responsible for breaking down protein and managing the waste. The liver produces urea as part of the body’s process of breaking down protein. The liver releases urea into the blood, and it travels to the kidneys for removal in the urine. Urea contains nitrogen and is also the compound responsible for helping clear excess nitrogen from the body. For this reason, people often refer to both “urea” and “urea nitrogen” as the same compound. This is not technically correct, but the two go hand-in-hand and measuring the level of this in the bloodstream helps to give a reliable indication of kidney and liver health. A component of many other blood tests, a doctor can order a BUN test for any person, ev...

What is a BUN test? A blood urea nitrogen (BUN) test is used to determine how well your kidneys are working. It does this by measuring the amount of urea nitrogen in the blood. Urea nitrogen is a waste product that’s created in the liver when the body breaks down proteins. Normally, the kidneys filter out this waste, and urinating removes it from the body. BUN levels tend to increase when the kidneys or liver are damaged. Having too much urea nitrogen in the blood can be a sign of kidney or liver problems. A BUN test is a blood test most commonly used to evaluate A BUN test can help diagnose the following conditions: • liver damage • • • • • • The test may even be used to determine the effectiveness of BUN tests are also often performed as part of regular checkups, during hospital stays, or during or after treatment for conditions like While a BUN test measures the amount of urea nitrogen in the blood, it doesn’t identify the cause of a higher or lower than average urea nitrogen count. A BUN test doesn’t require any special preparation. However, it’s important to tell your doctor if you’re taking any prescription or over-the-counter medications. Certain medications can affect your BUN levels. Some medications, including chloramphenicol or streptomycin, may lower your BUN levels. Other drugs, such as certain antibiotics and diuretics, may increase your BUN levels. Commonly prescribed medications that may raise your BUN levels include: • amphotericin B (AmBisome, Fungizone) ...

Mohammed Haneefa Nizamudeen/iStock/Getty Images Anatomy Each person has two kidneys. The kidneys are located on either side of the spine, with the top of each kidney beginning around the 11th or 12th rib space. The kidneys are sandwiched between the diaphragm and the intestines, closer to the back side of the abdomen. Roughly the size of a closed fist, each kidney measures about 10 to 12 centimeters long, 5 to 7 centimeters wide, and 3 to 5 centimeters thick. Each kidney is connected to the bladder through a ureter. The ureter brings waste products—urine—to the bladder, where it is stored until it leaves the body through the urethra. Together, all of these organs make up the renal system. As the blood passes through the kidneys, the vessels that carry the blood get smaller and smaller until they deliver blood to the nephrons. Each kidney contains about 1.3 million nephrons, which do the filtering work of the kidneys. Within each nephron, there is a microscopic filtration unit consisting of an exterior capsule—Bowman's capsule—and a network of tiny capillaries called glomerulus. As blood moves through the capillary network, or glomerulus, larger components are filtered out by tiny finger-like structures and the remaining blood passes to Bowman's capsule. From there, the filtered blood collects in Bowman's capsule until it is transferred to a system of tubules. While in the tubules, liquid and solutes will diffuse through additional layers of filtration. Some liquids and sol...
