Stability of B-type natriuretic peptide levels during exercise in patients with congestive heart failure: Implications for outpatient monitoring with B-type natriuretic peptide. 4. Note: When multiple specimens are drawn from a single venipuncture, the following order is recommended: (1) sterile blood culture tubes, (2) nonadditive clotting tubes (red), (3) coagulation tubes and tubes containing citrate (blue), (4) gel-barrier tubes and tubes with additives (red), (5) tubes containing heparin (green), (6) tubes containing EDTA (lavender, royal blue), (7) tubes containing acid citrate dextrose (yellow), and (8) tubes containing sodium fluoride and potassium oxalate (gray). BNP is predominantly secreted by the ventricles of the heart in response to increased pressure. B-type natriuretic peptide (BNP), also referred to as brain natriuretic peptide, is a member of a family of structurally similar peptide hormones that includes atrial natriuretic peptide.1 BNP is a 32-amino-acid peptide that contains a 17-amino-acid ring structure that is formed as the result of an internal disulfide bond. The comprehensive metabolic panel (CMP) usually includes 14 tests the 8 from the BMP as well as 2 protein tests ( albumin and total protein) and 4 liver tests ( ALP, ALT, AST, and bilirubin ). Some royal blue-top tubes do not contain EDTA. A discard tube is not required prior to collection of coagulation samples.4,5 When noncitrate tubes are collected for other tests, collect sterile and nonadditive (red-top) tubes prior to citrate (blue-top) tubes. To facilitate making the vein more prominent, the patient may be asked to hold firmly to a rubber ball, a thick wad of gauze, etc. 18.

A BNP or NT-proBNP test helps your provider diagnose heart failure and rule out other health conditions that cause similar symptoms. The film should be free of waves, holes, and ridges, and it should have a smooth appearance and feathered edge. Immunoreactive trypsin is technically more difficult than lipase and probably no better.2 The serum lipase:amylase ratio may help distinguish alcoholic from nonalcoholic pancreatitis. Well-prepared films can be used in performing the differential white cell count, for examining the morphology (size, structure, and shape) of red and white cells to determine the presence of abnormal cells, and also for the examination of the size and number of platelets. Put on laboratory personal protective equipment. Operate the centrifuge for no more than 10 minutes at the speed recommended by the manufacturer. This finding is frequent in hemolyzed specimens. Following the collection, preparation, and transport instructions suggested by LabCorp supports the best possible test results. Use: Serum or clotted whole blood. 2.

Use: Serum, may be used for assays requiring serum unless otherwise stated. In response to the coagulation process the fibrinolytic system is activated resulting in the conversion of plasminogen into plasmin, which cleaves fibrin (and fibrinogen) into the fragments D and E. Due to cross-linkage between D-domains in the fibrin clot, the action of plasmin releases fibrin degradation products with cross-linked D-domains.

Considerations for Single and Multiple Sample Collection. This test may exhibit interference when sample is collected from a person who is consuming a supplement with a high dose of biotin (also termed as vitamin B7 or B8, vitamin H, or coenzyme R). Providers use a BNP or an NT-proBNP test to diagnose heart failure. D-dimer levels are known to increase with age; eg, median D-dimer levels in apparently healthy men aged 75 to 79 are about twice as high as in men aged 60 to 64.19 This increase in the basal D-dimer concentration is responsible for the decrease in the specificity of D-dimer measurements for exclusion of VTE in the elderly. When frozen plasma is required, place plastic transport tube(s) immediately in the freezer compartment of the refrigerator, and notify your professional service representative that you have a frozen specimen to be picked up.
