由于公众不愿意参与艾滋病毒感染流行率的调查，早先提出了一种保密程序，即在k > 1的群体中检测血液样本。该程序固有的缺点是，它只能在感染率低于10%的情况下有效应用。在本文中，适用范围扩大到更高的患病率水平（高达约30%）。这是通过对每个个体采集两个样本并形成两组独立的分组来完成的，然后对其进行测试。对测试结果进行平均以产生新的估计。
Motivated by the reluctance of the public to participate in surveys of the prevalence of HIV infection, a procedure preserving confidentiality was earlier proposed, based on testing blood samples in groups of size k > 1. A disadvantage inherent in that procedure was that it could only be applied effectively where the prevalence of the infection was less than ten percent. In this paper the range of applicability is extended to higher levels of prevalence (up to about 30 percent). This is done by taking two samples per individual and forming two independent sets of groupings which are then tested. The results of the tests are averaged to yield a new estimate.
