Success of the new human papillomavirus (HPV) DNA test for low‐resource settings ( care HPV™ test; QIAGEN Gaithersburg Inc., Gaithersburg, MD) requires good test performance when operated by personnel with limited laboratory experience. We evaluated the transferability, reliability, and accuracy of the care HPV test nested within a cervical screening project in a large Nigerian village. Care HPV testing was performed on screen‐positive ( n = 345) and screen‐negative ( n = 42) women attending colposcopy (68.3% of referred). Biopsies of abnormal‐appearing areas were processed and read in the U.S. Care HPV specimens taken immediately before colposcopy were processed up to four times (in the field) by two secondary school graduates without laboratory experience, trained for this study. Specifically, QIAGEN Gaithersburg trained a laboratory‐inexperienced U.S. researcher, who trained the first local technician who, in turn, trained the second. Residual specimens were sent to the U.S. for MY09/MY11 PCR testing for 13 carcinogenic genotypes (HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 68) plus HPV66 (included in care HPV). Intrarater agreement was 98.8% (κ = 0.97) and 98.9% (κ = 0.97) for Technicians 1 and 2, respectively, while inter‐rater agreement was 96.3% (κ = 0.90). Agreement with MY09/MY11 PCR (virologic reference standard) was 89.3% (κ = 0.73) with 74.2% sensitivity and 95.7% specificity. The care HPV test detected 12 (80%) of 15 histologically confirmed cervical intraepithelial neoplasia Grade 2 (CIN2) or worse lesions, with an estimated 83.0% specificity to detect
