Instability of Plasma and Serum Progastrin-Releasing Peptide during Repeated Freezing and Thawing

Progastrin-releasing peptide (proGRP) is a promising biomarker for small cell lung cancer. However, not much is known about how sample processing and storage conditions affect the stability of proGRP. Here, we examined the effects of repeated freeze-thaw cycles on the stability of proGRP in plasma and serum.
