The author compared indices of thyroid function in 76 patients with panic attack and 80 control subjects. And SCL-90-R was performed to evaluate the relationship between the psychiatric symptoms and thyroid indices in the patients with panic attack The results were as follows: 1). No siginificant differences in T3, T4 or TSH were found between the two groups. But T3 level was significantly lower in male panic patients than male controls(p<0.005). 2) The T3 level was significantly lower in male panic patients who had higher depression socre than average in SCL-90-R(p<0.025). 3) The TSH level was significantly lower in patients with higher anxiety(p<0.001) and phobia(p<0.05) score and in female panic patients(p<0.001) with higher anxiety and phobia score than average in SCL-90-R. 4) The phobic symptom(p<0.001) was siginificantly higher and the T3 level(p<0.005) was lower in the male than the female patients with panic attack.

Purpose: To establish accurate external quality assurance (EQA) test, cross institutional and modality tests were performed using WHO certificated reference material (CRM) and same pooled patients serum. Materials and Methods: Accuracy and precision were evaluated using CRM and pooled patients' serum for AFP, CEA, PSA, CA 125, CA 19-9, T3, T4, Tg, TSH. To evaluate the accuracy and precision, recover test and coefficient variation were measured. RIA test were performed in major 5 RIA laboratory and EIA (CLIA) test were done in 5 major EIA laboratory. same sample of CRM and pooled serum were delivered to each laboratory. Results: In 2009, mean precision of total tumor marker of RIA was $14.8{\pm}4.2%$ and that of EIA(CLIA) was $19.2{\pm}6.9%$. In 2010, mean precision of 5 tumor marker and T3, T4, Tg, TSH was $13.8{\pm}6.1%$ in RIA and $15.5{\pm}7.7%$ in EIA (CLIA). There was no significant difference between RIA and EIA. In RIA, the coefficient variations (CV) of AFP, CEA, PSA, CA 125, T3, T4, TSH were within 20%. The CV of CA 19-9 was over 20% but there was no significant difference with EIA (CLIA) (p=0.345). In recovery test using CRM, AFP, PSA, T4, TSH showed 92~103% of recovery in RIA. In recovery test using commercial material, CEA, CA 125, CA 19-9 showed relatively lower recovery than CRM but there was no significant difference between RIA and EIA (CLIA). Conclusion: By evaluating the precision and accuracy of each test, EQA test could more accurately measured the quality of each test and performance of laboratory.
