NT-proBNP levels over 900 pg/mL may be a sign of heart failure. 2. The gel barrier prevents the remixing of the plasma with the cellular elements of the blood. Assessment of brain natriuretic peptide in patients with suspected heart failure: Comparison with radionuclide ventriculography data. This blood test measures the levels of a protein called BNP in your bloodstream. Collect blood into the BD PPT following standard procedure for venipuncture and sample collection. In some cases, additional time should be testing to when the result is released to the ordering provider. The BD PPT should be at room temperature and properly labeled for patient identification. If A small bore, sharp needle causes minimum patient discomfort; 22- or 23-gauge is the smallest bore (or lumen) size recommended to avoid hemolysis. Patients with subsegmental/peripheral PE or distal DVT may have a normal Innovance D-dimer result.9,10. 8. For more information, please view the literature below. This can cause discomfort to the patient and may also cause hemolysis. A syringe is usually used with patients who are difficult to collect by routine venipuncture procedure, including techniques using a safety-winged blood collection set (butterfly). 8.

We use cookies to ensure that we give you the best experience on our website. A tiny rubber sleeve automatically closes when the vacuum tube is removed from the holder, preventing leakage and loss of blood when the tubes are being changed. When your heart has to work harder to pump blood, it makes more BNP. Gently tap tubes containing additives to dislodge any material that may be adhering to the stopper. Note: If the blood has to be mixed with an additive (gently invert the tube 4 to 10 times depending on the specimen tube being used), this must be done immediately after collection. 0000425517 00000 n Use: EDTA whole blood or plasma. You may have a small bruise. Push the spreader slide rapidly over the entire length of the slide, pulling a thin smear of blood behind it. Remove the tube carefully without disturbing the contents. Also, print on the label the type of plasma submitted (eg, Plasma, Sodium Citrate, Plasma, EDTA, etc). Several studies on D-dimer for exclusion of venous thromboembolism (VTE) have been revaluated using an age-specific cutoff.20-23 The aim was to improve the effectiveness of D-dimer testing in ruling out VTE.20-23 The cutoff provided with the patient result is the manufacturer-determined value for exclusion of VTE; however, it has been determined that D-dimer values increase with age, and this can make VTE exclusion of an older population difficult. 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. How can the LabCorp patient mobile app help you? 8. 0000878985 00000 n Evaluation of patients with suspected acute pulmonary embolism: Best practice advice from the clinical guidelines committee of the American College of Physicians.
