Description

This Standard Reference Material (SRM) is intended for use in validating methods for determining folate vitamers in human serum, and for qualifying in-house control materials analyzed using those methods. A unit of NIST-3949 consists of one vial each of three materials: low (Level 1), medium (Level 3), and high (Level 2) folates. Each vial contains approximately 1.0 mL of frozen human serum. /// Sample value(s) - please ask for current certificate.
