Abstract: MEDICAL DIAGNOSIS OF RADIOIMMUNOASSAY FOR THE THP IN BLOOD AND UNINE zhu Guila Xu Sumei Chen Linna（Department of Nuclear Medicine,The Affiliated Hospital of Zhen jiang Medical Couege，212001）ABSTRACT The Tamm-Horsfall protein（THP）in bloob and urine of 10 1 healthy subjects and29 8 cases ofpatients with 8 different kinds of diseases are de tected by RIA kit.The average values of THP inheaIthy subjets' bIood and urine are l 59．89±51．57 ng/ml and 28．84±14．99 mg/24 h respective-ly，It is the same as detected by other authors. The resuIts show that the level of urine THP of Pa-tients ，including chronic renal failure，interstitiaI nephritis，chronic nephritis，lupus nephritis，diabet-ic nephritis and urinary infections，are much lower than that of heaIthy subjects（P＜0．001），but thelevel of blood THP,are only lower in 4 kinds diseases，e.g．chronic renal failure，interstitial nephri-tis，chronic nephritis and lupus nephritls.In addition，theβ_2-MG in blood and urine，albumin in urineand BUN，Cr in blood in 27 8 cases are detected．It is found that the total abnormal rate of the bloodand urine THP is quite lower than that of urine albumin and β_2-MG，but higher than blood BUN andCr.Key words kidney disease radioimmunoassay tamm-horsfall protein
