Purpose: Currently available human papillomavirus (HPV) detection devices are expensive, requiring a continuous power supply, high-priced reagents, skilled laboratory personnel, and infrastructure. These make it difficult to implement primary HPV screening in high-risk (HR) populations, particularly in low-income settings such as in India. The objective of our study was to evaluate the diagnostic performance of a point-of-care, portable, battery-operated device called Truenat, which detects 4 HR HPV genotypes (16, 18, 31, and 45), as a potentially cost-effective alternative to conventional HPV diagnostic tests.
Patients and methods: This was a single-site, blinded, cross-sectional study that evaluated the performance of the Trunat HPV-HR using cervical samples collected from nonpregnant women > 30 years old via consecutive sampling. The comparison was conducted against the Hybrid Capture 2 (HC2) method. All the positive samples were validated by 14 Real-TM Quant Kit.
Results: Of 615 cervical samples, the HR-HPV DNA test was positive in 78 women (12.7%) by HC2 and in 49 (8%) by Truenat. With the consideration of limited genotype inclusivity, the sensitivity and specificity of Truenat HPV-HR were 97.7% and 98.9%, respectively.
Conclusion: The performance of Truenat HPV-HR test was comparable to that of HC2 in the 4 HPV genotypes and would be appropriate to consider for use in primary HR cervical cancer screening and particularly in low-income settings.
