关于早期HIV婴幼儿诊断:
婴幼儿HIV早期诊断是一个重大的挑战。抗体检测在婴幼儿中无效,因为随着出生,母亲的抗体存在于婴儿的体内。事实上,对于大至15个月的婴儿,抗体检测仍可能产生假阳性结果。目前有一些替代方法可用于感染HIV的婴幼儿的早期诊断。许多方法使用分子生物学技术,特异性检测病毒DNA或RNA,可用于6周大婴儿的HIV诊断。
对于感染HIV的儿童,早期诊断至关重要。如果发现HIV阳性,患儿可在病情加重前,得到恰当的医疗护理。若发现HIV阴性,则母亲可得到恰当的辅导,以确保婴儿保持无HIV状态。

About Early HIV Infant Diagnosis
Diagnosing HIV in infants and young children is amajor challenge. Antibody tests are ineffective in children because themother's antibodies remain in the child's system following birth. Infact, antibody tests in infants may yield false positive results for up to 15months. There are a number of alternate methods available for early diagnosisof HIV infected infants. Many approaches use molecular techniques, specificallydetecting the viral DNA and/or RNA, which enables HIV diagnosis as early as sixweeks.
Early diagnosis is critical for children infectedwith HIV. If found HIV positive, they can receive appropriate medical carebefore they develop significant illness, and can remain healthy despite theirinfection. If found HIV negative, the mother can get appropriate counseling toensure their child maintains a HIV-
