Normal range for buncreatinine series#

High BUN-to-creatinine ratios occur with sudden (acute) kidney problems, which may be caused by shock or severe dehydration.A high BUN value may be caused by a high-protein diet, Addison's disease, or tissue damage (such as from severe burns), or from bleeding in the gastrointestinal tract.Be sure to tell your doctor about all the non-prescription and prescription medicines you take. High BUN levels can also be caused by low blood flow to the kidneys caused by dehydration or heart failure. Kidney damage can be caused by diabetes or high blood pressure that directly affects the kidneys. A high BUN value can mean kidney injury or disease is present.A value that isn't in the normal range may still be normal for you. Your doctor will also look at your results based on your age, health, and other factors. Your lab report should show the range that your lab uses for each test. A BUN-to-creatinine ratio can help your doctor check for problems, such as dehydration, that may cause abnormal BUN and creatinine levels.Įach lab has a different range for what's normal. Blood urea nitrogen (BUN) and creatinine tests can be used together to find the BUN-to-creatinine ratio (BUN:creatinine). The level of creatinine in your blood also tells how well your kidneys are working-a high creatinine level may mean your kidneys are not working properly. Blood urea nitrogen to creatinine ratio (BUN:creatinine)Ī BUN test may be done with a blood creatinine test. A low BUN level can occur normally in the second or third trimester of pregnancy. Liver disease or damage can lower your BUN level. Heart failure, dehydration, or a diet high in protein can also make your BUN level higher. If your kidneys are not able to remove urea from the blood normally, your BUN level rises.

Urea is made in the liver and passed out of your body in the urine.Ī BUN test is done to see how well your kidneys are working. Urea is made when protein is broken down in your body. Collection of urine to evaluate for blood, infection, or other urinary tract problems.A blood urea nitrogen (BUN) test measures the amount of nitrogen in your blood that comes from the waste product urea. Urine chemistry tests to measure the output of the kidneys. If any one of these tests is outside the normal range of values, the test should be reported as abnormal. A liver panel may contain any of the following tests.

Liver Function TestsĪ series of blood chemistry tests measuring enzymes excreted by the liver during abnormal functioning due to metastases, obstruction or other conditions. Used primarily to rule out a variety of benign conditions. Normal values: 1%-13% absorbed by thyroid after 2 hours 2-25% absorbed after 6 hours 15-45% absorbed after 24 hours. Measures ability of thyroid gland to accumulate, concentrate and retain iodine usually done at same time as a thyroid scan. Histochemistry of the bone marrow is a laboratory study performed in addition to the standard histologic analysis of the specimen. Pathologic examination of bone marrow biopsy specimen using special staining techniques to determine subclassification of the leukemia. Identifies presence of blood in stool reported as positive or negative Also called: Guaiac, Hematest, Occultest, Hemoccult, Benzidine, or Orthotoluidine test. The blood chemistry panel consists of 12 to 20 tests: Test Mean Corpuscular Hemoglobin Concentration (MCHC)īlood chemistries, SMA-12, SMAC-6, ACA, MSSP, and many other names, usually based on the piece of equipment in use. If one or more of the starred items is outside of the normal values, the CBC is considered abnormal. The table which follows indicates the portions of the CBC relevant to malignancies. The platelet count is usually ordered separately. CBC (Complete Blood Count) with PlateletsĬonsists of several tests on blood serum. BUN (Blood Urea Nitrogen)Ĭhemistry study of blood serum to measure the level of urea in the blood, a sign of impaired kidney function or urinary obstruction. Normal range may vary somewhat according to the brand of laboratory assay materials used. May be included in blood chemistry screening panel.
