Blood urea normal range

Electrolytes are substances that have a natural positive or negative electrical charge when dissolved in water. They help your body regulate chemical reactions, maintain the balance between fluids inside and outside your cells, and more. They’re also a key way to diagnose a wide range of medical conditions and diseases. Overview What are electrolytes? Electrolytes are substances that have a natural positive or negative electrical charge when dissolved in water. An adult's body is about 60% water, which means nearly every fluid and cell in your body contains electrolytes. They help your body regulate chemical reactions, maintain the balance between fluids inside and outside your cells, and more. Your body gets electrolytes or their components from what you eat and drink. Your kidneys filter excess electrolytes out of your body and into your urine. You also lose electrolytes when you sweat. Key terms to know: • Hyper-: A condition that starts with “hyper” means it involves too much of something. • Hypo-: A condition that starts with “hypo” means it involves too little of something. • Ion: An atom that has an electrical charge. • Cations: Ions with a positive charge. • Anions: Ions with a negative charge. • pH: A scale that measures whether a liquid is an acid or base. Your body’s natural blood pH is between 7.36 and 7.44. • Acidic: Has a pH of less than 7. • Neutral: Has a pH of 7. • Basic: Has a pH of more than 7 (basic is also known as “alkaline”). What do electrolytes do?...

BUN (blood urea nitrogen) and creatinine are two blood tests that can reveal a lot about your metabolism, kidney, liver, and overall health. And while they can be used separately, the BUN/creatinine ratio can help pinpoint important issues. Learn more about the BUN/creatinine ratio and what it can reveal about your health. What is the BUN/Creatinine Ratio? BUN measures the amount of urea in your blood. Urea is a waste product made in the liver as the body processes protein. This protein is mostly derived from the diet, but it can also result from tissue protein turnover [ Urea is removed by the kidneys, but the rate of removal depends on the needs of the body. The kidneys can return different amounts of urea into the bloodstream depending on factors such as hydration and blood pressure. High urea is an important marker of kidney dysfunction as well [ Creatinine, on the other hand, is a waste product created from the normal wear and tear of muscles. It is produced from creatine, a protein that helps generate energy for muscle contractions. Creatinine production essentially reflects muscle mass, and because this mass changes little from day to day, creatinine production tends to be fairly constant [ Creatinine is removed from the body by the kidneys, which filter almost all of it from the blood into the urine, at a fairly constant rate. That is why blood levels are usually a good indicator of how well your kidneys are working [ So to recap, BUN levels fluctuate, while creati...

• Your liver produces ammonia — which contains nitrogen — after it breaks down proteins used by your body's cells. • The nitrogen combines with other elements, such as carbon, hydrogen and oxygen, to form urea, which is a chemical waste product. • The urea travels from your liver to your kidneys through your bloodstream. • Healthy kidneys filter urea and remove other waste products from your blood. • The filtered waste products leave your body through urine. A BUN test can reveal whether your urea nitrogen levels are higher than normal, suggesting that your kidneys may not be working properly. Why it's done You may need a BUN test: • If your doctor suspects that you have kidney disease or damage • If your kidney function needs to be evaluated, especially if you have a chronic condition such as diabetes or high blood pressure • To help determine the effectiveness of dialysis treatment if you're receiving hemodialysis or peritoneal dialysis • As part of a blood test group to help diagnose a number of other conditions, such as liver damage, urinary tract obstruction, congestive heart failure or gastrointestinal bleeding — although an abnormal BUN test result alone doesn't confirm any of these conditions If kidney problems are the main concern, the creatinine levels in your blood will likely also be measured when your blood is tested for urea nitrogen levels. Creatinine is another waste product that healthy kidneys filter out of your body through urine. High levels of creatini...
