Low calcium can be due to certain metabolic disorders or use of diuretics. High levels can be due to use of diuretics or kidney problems. Indicate the sodium, potassium, chloride and bicarbonate balance in your body. Chloride generally increases or decreases in direct relationship to sodium.

Important in maintaining normal levels of water in the body. Any value outside the expected range, high or low, requires medical evaluation. Important for the proper functioning of the nerves and muscles, particularly the heart. High levels may indicate excessive sodium intake or kidney disease. Low sodium levels may indicate diuretic usage or excessive water intake in patients with heart or liver disease. This is used in making a definitive diagnosis about the cause for elevated BUN and/or Creatinine levels. The mathematical relationship of the two. Low levels may indicate liver disease or decreased muscle mass. People with large muscle masses may have elevated levels. High values, especially with high BUN levels, may indicate problems with kidneys or muscle damage. Low levels may indicate an iron deficient diet. High levels may indicate kidney disease, congestive heart failure or severe burns. Abnormal values require further evaluation. This is a measure of the sugar level in your blood. High levels seem to be associated with low incidence of coronary heart disease. HDL CholesterolĪ “good cholesterol.” It protects against heart disease. An LDL level of less than 130 is recommended. LDL CholesterolĬonsidered “bad cholesterol” because cholesterol deposits form in the arteries when LDL levels are high. Our bodies need a certain amount to function properly. High cholesterol is a major risk factor for heart and blood vessel disease. CholesterolĬholesterol is different from most tests in that it is not used to diagnose or monitor a disease, but is used to estimate risk of developing a disease – specifically heart disease. High levels may also indicate poorly controlled diabetes. Triglyceridesīlood tests used to identify the risk of developing heart disease. I urge you to discuss your results, especially any abnormalities, with your physician. Only your doctor can determine if further testing or treatment is needed. An abnormal result does not necessarily indicate illness. Most laboratories set their normal range for a particular test so that 95% of healthy patients fall within the normal range. These variations may be due to such things as race, diet, age, sex, menstrual cycle, physical activity, medications and alcohol intake. Some disorders related to a low BUN level in the blood are pregnancy and acromegaly.It is important to realize that laboratory results may be outside of the so-called “normal range” for many reasons. If kidneys do not work properly urea remains in the bloodstream and its concentration in the blood will be abnormally higher.Ī BUN level below the normal range may be a sign of a low-protein diet or a liver disorder (the liver is not doing a proper protein metabolism). Kidney disorders ( kidney failure, nephropathies, etc.).High protein catabolism (due to an excessive consumption of proteins, etc.).A decrease in the plasma volume due to dehydration or upper GI (gastrointestinal) bleeding.Urea level in the blood is directly related to nutrition, protein metabolism/catabolism and renal functionality.Ī high level of BUN in the blood may be due to: Urea is a marker for kidneys and liver activity. Maximum values increase with the age and are higher in elderly people. Age is an important factor to normal ranges.If your test is expressed in urea you must convert the values from urea to BUN or the information given will not be specific for your case. Warning: In this page we talk about BUN levels. It important to know if the values measured are the BUN levels used in the US and other countries or instead the values measured are the total urea used in Europe and around the world.

There are some circumstances to take into account about BUN normal ranges in the blood: Your doctor will study the results along with your medical record, screenings, physical condition, symptoms and any other relevant information about your situation. There may be also slight differences in the normal levels according to age, gender, race or ethnic origin, geographic region, diet, type of sample and other relevant status. These ranges depend on the makeup of the local population, the technologies used and the accuracy of the measurement. Each laboratory must establish its own normal ranges for BUN in the blood.
