  • Publication number: 20230314292
    Abstract: The present invention relates to a diluted solution for measuring free steroids in blood and a method for measuring free steroids using the same, and more particularly, to a method for preparing a diluted blood sample for measuring free steroids in blood and a composition for blood sample dilution solution. In the method for preparing a diluted blood sample for measuring free steroids in blood of the present invention, it was confirmed that physiologically active free cortisol could be evaluated with the cortisol enzyme immunoreaction detection kit without additional sample pretreatment by removing cortisol which is present by binding to excess albumin and cortisol-specific corticosteroid-binding globulin (CBG) contained in serum using a protein precipitation and neutralizing agent. In addition, by selectively removing the protein in the blood sample, it is possible to measure low molecular weight compounds, including steroids, which are strongly bound to proteins in the blood, such as cortisol, in free form.
