Stability of plasma analytes after delayed separation of whole blood: implications for epidemiological studies.

Journal article

BACKGROUND: Large blood-based epidemiological studies require simple, cost-effective sample collection methods. Immediate sample separation or rapid transport of chilled blood samples to a central laboratory may be impractical or prohibitively expensive. To assess the feasibility and reliability of transporting blood samples over several days at ambient temperature (e.g. by mail), we evaluated the stability of various plasma analytes in samples stored at room temperature or chilled. METHODS: ...
