Outreach clients: Due to short stability and processing requirements for this test, sharing BNP specimen with other testing is not recommended. Please submit one specimen for B-Type Natriuretic Peptide and a second EDTA specimen for other requests.
If two specimens are not submitted, we may need to cancel the BNP test due to specimen stability.
