The acylated (<scp>AG</scp>) to unacylated (<scp>UAG</scp>) ghrelin ratio in esterase inhibitor‐treated blood is higher than previously described

Abstract

AG and UAG levels measured in AEBSF-stabilized plasma indicate that the AG/UAG ratio is markedly higher than previously described and that UAG is a physiological component of the circulation. This highlights the importance of immediately stabilizing blood samples on collection for determination of both AG and UAG concentrations and provides a valuable tool for their measurement in physiological and interventional studies.
