Abstract: OBSERVATION ON THE STABILITY OF THE SOLID PHASE MICROPARTICLES SEPARATING TECHNIQUE IN T_3，T_4 RADIOIMMUNOASSAY Chen Guangliang（Department of Nuclear Medicine,Bengbu Medical College,233003）Chen Xunmin（Medicine lab of Huaibei peple's Hospital,235000）ABSTRACT The solid dphase T_3，T_4 RIA is adopted at various laboratories．The data analysis from the effeclivte dcose and quality control of samples indicates that the separation technique is of good effect and high sta-bility. It is effective separation technique for the quality control in RIA.Key words microparticles separation technique stability radioimmunoassay
