진단 검사의학과와 중복되는 검사들의 결과 비교, 분석(TSH, FT₄, AFP, CEA, PSA)

Comparison of Result Between NM and LM

Purpose: Nowadays, NM (in vitro lab) and LM (TLA lab) are overlaped in almost all tests. in this case, how can NM develop continually in a keen competition with LM. we studied to find out current situation and problems after comparing NM with LM. Then, to improve our technic. Methods and meterials: We studied from October 2008 to February 2009 at department of nuclear medicine Seoul National University Bundang Hospital visited 108 patients. We assayed TSH, FT₄ by Ria-mat{TSH (n=23), FT₄ (n=19)} and AFP, CEA, PSA by manual. {AFP (n=24), CEA (n=31), PSA (n=31)}. On the other hand, LM was measured by TLA system. Results: NM was similar to LM (value of AFP), NM<LM (value of CEA), NM>LM (value of PSA,TSH), NM≦LM (value of FT₄ in range 0.01~1.00 ng/mL), NM≧LM (value of FT₄ in range 1.00~ 6.00 ng/mL) Conclusions: There was no test which result showed big difference remarkably, but several tests have some difference totally or partly. It means that there is possibility to judge wrongly (normal patient->abnormal, abnormal->normal). So, we need to consider always when we report the result.
