由于 HIV-1 和 HV-2 在几内亚科纳克里同时流行,准确的诊断和鉴别诊断对于治疗至关重要。因此,对四种快速 HIV 检测的 HIV-1 和 HIV-2 诊断和区分能力进行了评估,以供几内亚科纳克里使用。其中包括 SD Bioline HIV 1/2 3.0 (Standard Diagnostics Inc.)、Genie II HIV1/HIV2 (Bio-Rad)、First Response HIV Card Test 1–2.0 (PMC Medical) 和Immunoflow HIV1-HIV2 (Core Diagnostics)。结果与金标准测试(INNO-LIA HIV-I/II 评分)和 NEW LAV BLOT II (Bio-Rad) 进行比较。对 443 个连续储存的已知 HIV 类型的 HIV 阳性血清样本进行了评估。 Genie II HIV1/HIV2、Immunoflow HIV1-HIV2 和 SD Bioline HIV 1/2 3.0 的灵敏度为 100%(95% CI,98.9–100%),而 First Response HIV Card Test 1–2.0 的灵敏度为 99.5%(95% CI,98.2%-99.9%)。在区分能力方面,Genie II HIV1/HIV2 识别出 382/ 384(99.5%) HIV-1 样本、49/ 52(95%) HIV-2 和 7/7(100%) HIV 阳性不可分型样本。 Immunoflow HIV1-HIV2 识别出 99% 的 HIV-1、67% 的 HIV-2 和所有 HIV 阳性的无法分型的样本。第一响应 HIV 卡测试 1-2.0 识别出 94% HIV-1、64% HIV-2 和 57% HIV 阳性的无法分型样本。 SD-Bioline HIV 1/2 3.0 是整体表现最差的测试,可识别 65% HIV-1、69% HIV-2 和所有 HIV 阳性的不可分型样本。使用 SD Bioline HIV 1/2 3.0(几内亚科纳克里的现行标准)作为歧视性 HIV 测试效果不佳,最好用Immunoflow HIV1-HIV2 替代。
With both HIV-1 and HV-2 prevalent in Guinea-Conakry, accurate diagnosis and differentiation is crucial for treatment purposes. Thus, four rapid HIV tests were evaluated for their HIV-1 and HIV-2 diagnostic and discriminative capacity for use in Guinea-Conakry. These included SD Bioline HIV 1/2 3.0 (Standard Diagnostics Inc.), Genie II HIV1/HIV2 (Bio-Rad), First Response HIV Card Test 1–2.0 (PMC Medical) and Immunoflow HIV1-HIV2 (Core Diagnostics). Results were compared with gold standard tests (INNO-LIA HIV-I/II Score) and NEW LAV BLOT II (Bio-Rad). Four hundred and forty three sequential stored HIV-positive serum samples, of known HIV-type, were evaluated. Genie II HIV1/HIV2, Immunoflow HIV1-HIV2 and SD Bioline HIV 1/2 3.0 had 100% sensitivity (95% CI, 98.9–100%) while for First Response HIV Card Test 1–2.0 this was 99.5% (95% CI, 98.2%-99.9%). In terms of discriminatory capacity, Genie II HIV1/HIV2 identified 382/ 384(99.5%) HIV-1 samples, 49/ 52(95%) HIV-2 and 7/7(100%) HIV-positive untypable samples. Immunoflow HIV1-HIV2 identified 99% HIV-1, 67% HIV-2 and all HIV-positive untypable samples. First Response HIV Card Test 1–2.0 identified 94% HIV-1, 64% HIV-2 and 57% HIV-positive untypable samples. SD-Bioline HIV 1/2 3.0 was the worst overall performer identifying 65% HIV-1, 69% HIV-2 and all HIV-positive untypable samples.The use of SD Bioline HIV 1/2 3.0 (the current standard in Guinea-Conakry) as a discriminatory HIV test is poor and may be best replaced by Immunoflow HIV1-HIV2.
