Immunologic test)
● 응집반응 억제의 원리를 이용하여 임부의 혈액이나 소변에 나타나는 hCG의 존재유무를 검사하는 방법
● 예정 월경일이 지난 지 4-10일 사이에 정확한 검사를 할 수 있음
● 정맥혈의 약 7ml를 혈액검사를 위해 채취
● 대부분의 소변검사는 아침 첫 소변을 사용
이유 : 아침 첫 소변
afferent C-fiber

Laboratory Monitoring of Patients with HIV Infection
Patients with CD4+ T cell counts <200/L are at high risk of disease from P. jiroveci, while patients with CD4+ T cell counts <50/L are at high risk of disease from CMV, mycobacteria of the M. avium complex (MAC), and/or T. gondii. Patients with HIV infection should have CD4+ T cell measurements performed at the time of diagnosis and every 3&
