A six-part differential reported in some lab locations includes IG % and IG absolute counts. Nevertheless, complete elimination of this interference from all patient specimens cannot be guaranteed. (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.). 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. 140889: B-Type Natriuretic Peptide (BNP) | Labcorp 12.

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). If a frozen specimen is not required, it is not necessary to transfer serum to a plastic transport tube. 6. The essential difference between plasma and serum is that plasma retains fibrinogen (the clotting component), which is removed from serum. 1.

This step embeds the full point of the needle in the stopper without puncturing it, preventing blood leakage on venipuncture and the premature loss of vacuum. Prolonged centrifugation may cause hemolysis. Send serum in a plastic transport tube. To allow adequate mixing, slowly invert the tube eight to ten times (four times for citrate tubes) using a gentle wrist rotation motion. Rest the left end of the spreader at a 45 angle, approximately inch opposite the drop of blood on the slide. Also, because hemolysis interferes with many procedures, please submit samples that are as free from hemolysis as possible. A double-pointed needle or multiple sample needle (both disposable) may be used for venipuncture. (Note: This volume does not allow for repeat testing.). The results of a BNP test or NT-proBNP test also allow your provider to plan treatments and monitor how well theyre working. Patient samples may contain heterophilic antibodies (eg, human antimouse antibodies [HAMA] and rheumatoid factors) that could react in immunoassays to yield falsely elevated results. (See Figure 7.).

Every person has their own range of BNP or NT-proBNP level range. 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.

Place the tube(s) in a designated freezer. 0000032001 00000 n Failure to fill the tube will cause an improper blood-to-anticoagulant ratio and yield questionable and/or QNS test results. This assay has been designed to minimize interference from heterophilic antibodies. Blood cells are suspended in the plasma, which is made up of water and dissolved materials, including hormones, antibodies, and enzymes that are being carried to the tissues, and cellular waste products that are being carried to the lungs and kidneys. A possible physiologic explanation for the appearance of immature granulocytes in the peripheral blood of pregnant women, increased alkaline phosphate activity in granulocytes, and increased glycogen content of lymphocytes may be found in the excretion curves of hormones during pregnancy. For people who dont have heart failure, normal BNP levels are less than 100 picograms per milliliter (pg/mL). Plasma Preparation Tube (PPT): Contains EDTA. Send plasma in a plastic transport tube labeled Plasma, Sodium Citrate. Send whole blood in a blue-top tube. WebB-Type Natriuretic Peptide (BNP) Test code: 37386 Question 1. If youve received a heart failure diagnosis, there are things you can do to live with heart failure, including lifestyle and dietary changes. This angle prevents the white cells from bunching along the edges. Failure to keep the entire edge of the spreader slide against the slide while making the film.
