To avoid clotting, gently mix the blood with the anticoagulant immediately after drawing each sample. 9. Detection of D-dimers, which specifies cross-linked fibrin degradation products generated by reactive fibrinolysis, is an indicator of coagulation activity. The Innovance D-dimer assay is intended for use in conjunction with a nonhigh clinical pretest probability (PTP) assessment model to exclude deep vein thrombosis (DVT) and pulmonary embolism (PE).6 This test can be used to exclude VTE with nonhigh pretest probability (ie, low or low/moderate pretest probability). BNP levels over 100 pg/mL may be a sign of heart failure. 0000947383 00000 n A properly executed Advance Beneficiary Notice (ABN) must be submitted with the specimen if medical necessity is not demonstrated by the ICD code chosen. 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.
