In resource-limited settings, CD4 testing is a barrier to antiretroviral therapy initiation in pregnancy.
We used logistic regression to identify predictors of CD4 cell count ≤ 350 cells/uL in 20,233 pregnant women.
The best-performing model included any 3 of: age ≥ 28 years old, hemoglobin ≤ 9.8 g/dL, gestational age ≤ 30 weeks, weight ≤ 64 kg, history of tuberculosis or previous death of an infant prior to one year old. Sensitivity was 45.7% (95% CI: 44.5-47.0), specificity 70.7% (95% CI: 69.6-71.8), and misclassification rate 41.4% (95% CI: 40.5-42.2).
CD4 triage remains a critical element of maternal HIV care and PMTCT.
在资源有限的情况下，CD4 检测是限制孕妇启动抗逆转录病毒治疗的一个障碍。
我们使用逻辑回归分析方法，确定了 20233 名孕妇的 CD4 细胞计数≤350 个/μL 的预测因素。
表现最佳的模型包括以下任意 3 项：年龄≥28 岁、血红蛋白≤9.8g/dL、妊娠周数≤30 周、体重≤64kg、结核病病史或之前有婴儿在一岁前死亡。该模型的敏感性为 45.7%（95%CI：44.5-47.0），特异性为 70.7%（95%CI：69.6-71.8），错误分类率为 41.4%（95%CI：40.5-42.2）。
CD4 分类仍然是孕产妇 HIV 护理和 PMTCT 的一个关键要素。
