(See Figure 13. 0000010201 00000 n A BNP test is done by drawing blood from a vein in your arm using a hypodermic needle. Some royal blue-top tubes do not contain EDTA. What level of BNP indicates heart failure? When more than one blood specimen is required, multiple sample needles and vacuum tubes make blood collection simpler and more efficient. WebBlue-top tube (also light blue-top tube): Contains sodium citrate. You dont need to do anything to prepare for a BNP test or NT-proBNP test. Label the specimen appropriately. (Use of a fixed angle rotor centrifuge does not allow the gel barrier to form properly and may result in incomplete separation of plasma from the cellular components.). Transfer the serum from the pipette into the transport tube. Hold the left corners of the collection slide with the left thumb and forefinger. They found that a BNP value >80 pg/mL could be used to identify patients with CHF from this population with a sensitivity of 97%, specificity of 98%, positive predictive value of 92%, and a negative predictive value of 98%.6. The blood film (commonly called a blood smear) can be a vital part of clinical testing. Palareti G, Cosmi B. A B-type natriuretic peptide (BNP) test is a blood test. %%EOF Your provider will let you know when the results are ready. Maisel and coworkers4 found that a BNP cutoff of 75 pg/mL could be used to predict systolic and/or diastolic abnormalities accurately in symptomatic patients referred to echocardiology for left ventricular function studies. A small bore, sharp needle causes minimum patient discomfort; 22- or 23-gauge is the smallest bore (or lumen) size recommended to avoid hemolysis. The panel is also often ordered when you are ill, in the hospital, or in the emergency room. At some patient service centers, Labcorp provides biometric screening, which includes height, weight, blood pressure, waist circumference, body mass index (BMI), and blood draw for wellness screening. Failure to keep or have the spreader slide at approximately a 45 angle. 140889: B-Type Natriuretic Peptide (BNP) | Labcorp Gottfried EL, Adachi MM. 0000731797 00000 n Follow these steps: There are two important guidelines to follow when submitting blood specimens. Lipase activity is usually absent in urine, possibly from inactivation of the enzyme. When performed, it enables the technologist to view the actual physical appearance of the red and white blood cells microscopically. Operate the centrifuge for 10 minutes at the speed recommended by the manufacturer. Note: LabCorp works with health care providers to minimize the total volume collected from pediatric and geriatric patients. Do not use gel-barrier tubes to submit specimens for therapeutic drug monitoring. McNairy M, Gardetto N, Clopton P, et al. ( Note: This volume does not allow for repeat testing.) We have methods to check for biotin interference as well as for any other interferences and for the accuracy of the results. The Frozen Specimen Keeper will be left in your lockbox for reuse. Remove the tube carefully without disturbing the contents. Diagnose pancreatitis, more specific for pancreatitis than is serum amylase; diagnose peritonitis, strangulated or infarcted bowel, pancreatic cyst. Top 3Reference Laboratory Test Catalogs for MiscellaneousLab TestOrders: Aiding in the diagnosis and assessment of disease severity in congestive heart failure (CHF), plus risk stratification in acute coronary syndromes (ACS). Blood should be collected in a blue-top tube containing 3.2% buffered sodium citrate.1 Evacuated collection tubes must be filled to completion to ensure a proper blood to anticoagulant ratio.2,3 The sample should be mixed immediately by gentle inversion at least six times to ensure adequate mixing of the anticoagulant with the blood.
