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. 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). Operate the centrifuge for 10 minutes at the speed recommended by the manufacturer. Collect blood into the BD PPT following standard procedure for venipuncture and sample collection. 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). The aseptic method of collecting and transporting a blood specimen works on the principle of a vacuum tube for drawing blood. 0000383639 00000 n 4 0 obj <> endobj xref 0 Ratios >2 (expressed as multiples of the upper limits of normal) suggest an alcoholic etiology.3 Lipase isoform or isoenzymes have been studied.4. When more than one blood specimen is required, multiple sample needles and vacuum tubes make blood collection simpler and more efficient. (See Figure 5.)

The negative predictive value is further enhanced through the use of a clinical probability model along with D-dimer in the decision process.12-15 Values less than 0.5 mg/L FEU in an individual with a low clinical risk of venous thrombosis can serve as the basis for not performing more expensive diagnostic tests for DVT and PE.

Because additives are not interchangeable, it is necessary to consult the specimen requirement field of individual test descriptions to determine the appropriate collection requirements for the test ordered. To address this, the American College of Physicians, based on best available evidence and recent guidelines, recommends that clinicians use age-adjusted D-dimer thresholds in patients greater than 50 years of age with: (a) a low probability of PE who do not meet all "pulmonary-embolism-rule-out criteria," or (b) in those with intermediate probability of PE.21 The formula for an age-adjusted D-dimer cutoff is "age/100." Your provider will let you know when to expect results and explain what they mean.

B-type natriuretic peptide (BNP) testing is a blood test that shows the level of the hormone BNP. Failure to fill the tube will cause an improper blood-to-anticoagulant ratio and may yield questionable and/or QNS test results. This will cause a shift in fluid between the vein and the surrounding tissue. Depending on the results of the BNP test, your provider may order follow-up tests, such as an electrocardiogram (EKG or ECG). To ensure adequate mixing, gently invert the BD PPT eight to ten times using a gentle wrist rotation motion. In some cases, additional time should be Why are my labcorp results taking so long? For example, a 60-year-old patient would have an age-adjusted cutoff of 0.6 mg/L FEU, and an 80-year-old patient would have an age-adjusted cutoff of 0.8 mg/L FEU. 0000425517 00000 n There is a significant increase of normoblastic erythropoiesis and, to a lesser extent, of granulopoiesis during pregnancy, which is associated with an increase in immature cells (shift to the left) of both erythropoietic and granulopoietic tissues.
