Ultrasonography is one of the fields on the imaging studies within intra-abdominal organs. A blood test is a typical method of clinical chemical examination on the in vivo test of clinical symptoms. Fatty liver is performed simultaneously two kinds of diagnostics methods, intra-abdominal ultrasound and blood tests. At an implementing this, the standard of blood tests value was the TBIL, TC, AST, ALT, ALP, GGT, TG, HDL-C, GLU. In this study analyzing the accuracy of the two kinds of test, ultrasonography and blood test, on patients with fatty liver. From January to March 2012, patients 459 determined fatty liver within 1350, who received health examination simultaneously on the intra-abdominal ultrasonography and blood tests. Same result of ultrasonography and blood test's patients were 459 ie, 60.8%. and different result of those examinations was 280 ie, 39.2%. Consequently diagnostic accuracy was 60.8%. It presumably caused by differences in the diagnostic performance of ultrasound professionals(Radiologist or Radiological Technologist). In order to overcome this, ongoing educational and study will be needed.

현재 서울대학교 병원에서 실시하는 300여 가지의 검사중에서 약200여 가지가 혈액으로 실시된다 그러므로 혈액검사를 실시하였다고 하면 어느 특정한 검사를 말하는 것이 아니고 단지 혈액이라는 검체를 사용했다는 뜻이다.

Suppose we have g itesm classified as defective or as nondefective. If we test each item separately, then g tests are required. However, it is possible to test a group of g items so as to detect whether at least one of them is defective, and to proceed to individual testing only if the presense of at least one defective item is indicated. The method is called Dorfman procedure. In this paper, we consider a variant of Dorfman procedure called a hierarchal dorfman procedure. We also consider the curtailment effect resulted from the dependency of the tests. We propose an efficient blood testing procedure. We also present ot heuristic rule of thumb which is simple and easily implementable.

건강검진이나 질병을 진단받기 위해 가장 먼저 거쳐야 할 관문은 노란 고무줄을 팔에 묶고 팔꿈치가 따끔한 주삿바늘을 참아 내는 것이다. 이 검사가 바로 피검사라 하는 혈액검사다. 혈액 검사로 모든 혈액 속 물질들의 결과를 알 수 있다고 하는데, 대체 어디까지 알 수 있는 것일까?

국내에서 수혈되는 혈액에 대해서도 선진국에서 실시하고 있는 핵산증폭검사가 올해 하반기부터 적용될 예정이다. 핵산증폭검사의 실시로 혈액제제로 안전성은 그 어느 때보다도 높아질 예정이다.

Park et. al (2010) proposed a statistical model for determining the admission or discharge of 668 patients with a chief complaint of dyspnea by the number of 11 blood tests belonging to the corresponding discharge intervals. Since this method does not take into consideration the importance of each blood test result, its performance might not be optimally good. In this study, we employ a quantification method to evaluate the importance of those blood test results, and then provide a new statistical mode that takes the importance into consideration. The results show that the performance of this new model is a little better than that of the model by Park et. al (2010).

Purpose: The aim of this study was to assess the benefits of routine pre-endoscopy coagulation screening tests and platelet counts in Korean children. Methods: Between March 2004 and December 2009, children who underwent gastrointestinal endoscopy for the evaluation of various gastrointestinal symptoms were included. All of the subjects included in the study also underwent routine coagulation screening and platelet count determinations prior to endoscopy and biopsy. The clinical records and laboratory tests were retrospectively reviewed in all patients. Results: One hundred sixty-two of 1,476 (11%) patients who underwent endoscopy had abnormal results on pre-screening coagulation tests. Fourteen patients underwent coagulation factor assays due to abnormal clotting results in consecutive tests or due to clinical evidence of a bleeding tendency. Seven patients were diagnosed with factor XII deficiency, one patient was diagnosed with von Willebrand disease, one patient had von Willebrand disease and factor XII deficiency, and one patient was presumed to have mild hemophilia. The remaining 4 patients had normal results with the factor assays. The results of platelet counts were normal with the exception of 1 patient. No patient had significant bleeding during the endoscopic procedures, despite abnormal pre-endoscopic coagulation tests. Conclusion: Routine coagulation screening tests and platelet counts revealed abnormal results in some patients. Most of the patients with abnormal clotting were shown to have a factor XII deficiency, which had no significant associated bleeding tendencies; the other patients were diagnosed with hemophilia or von Willebrand disease. Therefore, although abnormal pre-endoscopic coagulation is not always related to significant bleeding complications, pre-endoscopic coagulation screening may be useful in some children in predicting the risk of bleeding tendency during endoscopic procedures.

As a test for diagnosing fatty liver, recently, ultrasound and blood exam are being performed simultaneously. In particular, in the case of high-sensitivity C-reactive protein in blood exam, it is used as an index indicating the level of inflammation in various parts of the body as well as cardiovascular diseases. Thus, this study was conducted to analyze the association between metabolic syndrome components, liver function, and high-sensitivity C-reactive protein levels according to the degree of nonalcoholic fatty liver, and use it as a clinical indicator for fatty liver diagnosis. Metabolic syndrome components, liver function and high-sensitivity C-reactive protein blood test values analyzed from 1,139 men and women over 20 years of age with nonalcoholic fatty liver in abdominal ultrasonography from March 2021 to August 2021 at the Korea Association of Health Promotion, Gwangju-Jeonnam Branch. Analyzed for all men and women, the blood test values for subjects with mild fatty liver were AST 30 U/L, ALT 32.1 U/L, γ-GTP 41.2 IU/L, and hs-CRP 0.14 mg/dL. These values were lower than the blood test values of subjects with moderate fatty liver (AST 38 U/L, ALT 47.6 U/L, γ-GTP 54.9 IU/L, hs-CRP 0.22 mg/dL) and was statistically significant (p<0.001). In this case of high-sensitivity C-reactive protein test, it is statistically significant, showing higher values in Subjects with moderate fatty liver than Subjects with mild fatty liver. thus, it is considered that hs-CRP can be used as clinical data for the prevention and management of fatty liver.

만성간질환의 조기 발견과 적절한 관리는 중증 질환으로 진행을 차단하거나 완치하는데 큰 역할을 할 수 있다. 만성간질환을 진단하는 Gold Standard는 조직검사이지만 시간적·비용적인 측면에서 제한점이 있다. 현재 만성간질환 진단을 위해 최우선 시행하고 있는 검사는 혈액검사이며 진단정확도가 낮은 것으로 보고된다. 영상진단검사는 검사비용 측면에서 혈액검사보다 비싸며 진단정확도 측면에서 조직검사를 대체하기에는 정확도 향상이 요구된다. 본 연구에서는 획득된 의료영상을 활용하여 간세포 이질성과 결정성을 신속하게 정량 분석할 수 있는 소프트웨어를 개발하고 만성간질환 환자를 대상으로 정량 평가함으로서 임상활용 가능성을 확인하고자 한다.
