Special Info
Plasma or visibly hemolyzed specimens are unacceptable. Specimens stored or transported at room temperature for more than 48 hours are not acceptable. This test is New York DOH approved.
Clinical Info
Use for prognostication in heart failure. This test complements the prognostic value of N-terminal pro-brain natriuretic peptide (NT-proBNP). An elevated concentration of galectin-3 is associated with increased cardiovascular risk and adverse outcome in patients with heart failure. Medical management should rely on clinical findings. Low risk: < or = 17.8 ng/mL; Intermediate risk: 17.9 - 25.9 ng/mL; Higher risk: > 25.9 ng/mL.
