Abstract
Growth differentiation factor-15 (GDF-15), a member of the transforming growth factor (TGF-β) superfamily, and is expressed and secreted in response to inflammation, oxidative stress and hypoxia. It has been shown in several studies to be a predictor of heart failure. However, the only kits available on the market are ELISA kits, which are costly and error-prone and are not conducive for clinical use. Here, we developed a chemiluminescence kit which optimized the reaction conditions and the reaction time was reduced to 10 min. We further proved that it can be used to measure GDF-15 in serum or plasma accurately and fastly, and provide additional information for the diagnosis of heart failure disease. Methodological comparison and clinical study verified this method is a reliable, economical and highly automated blood test method.•All necessary steps and the reagents needed are provided.•Reliability of the chemiluminescence immunoassay was verified by analyzing serum GDF-15 levels from different groups.•GDF-15 can provide clinicians with reliable prediction and disease assessment of heart failure.
