摘要The accurate and timely detection of biochemical coagulation indicators is pivotal in pulmonary and critical care medicine.Despite their reliability,traditional laboratories often lag in terms of rapid diagnosis.Point-of-care testing(POCT)has emerged as a promising alternative,which is awaiting rigorous validation.We assessed 226 samples from patients at the First Affiliated Hospital of Guangzhou Medical University using a Beckman Coulter AU5821 and a PUSHKANG POCT Biochemistry Analyzer MS100.Furthermore,350 samples were evaluated with a Stago coagulation analyzer STAR MAX and a PUSHKANG POCT Coagulation Analyzer MC100.Metrics included thirteen biochemical indexes,such as albumin,and five coagulation indices,such as prothrombin time.Comparisons were drawn against the PUSHKANG POCT analyzer.Bland-Altman plots(MS100:0.8206?0.9995;MC100:0.8318?0.9911)evinced significant consistency between methodologies.Spearman correlation pinpointed a potent linear association between conventional devices and the PUSHKANG POCT analyzer,further underscored by a robust correlation coefficient(MS100:0.713?0.949;MC100:0.593?0.950).The PUSHKANG POCT was validated as a dependable tool for serum and whole blood biochemical and coagulation diagnostics.This emphasizes its prospective clinical efficacy,offering clinicians a swift diagnostic tool and heralding a new era of enhanced patient care outcomes.
