China Medical Technologies Inc, a China-based advanced in-vitro diagnostic company, announces the recent publication of a large sample study on the Company’s SPR analyzer and related HPV DNA chip (the SPR System) for the detection of 16 high risk and 8 low risk genotypes of human papillomavirus (HPV).

The study tested specimens of 560 patients with atypical squamous cells of undetermined significance (ASCUS) or above using the SPR System and compared the results with sequence analysis. The study concluded that the SPR System is highly sensitive and specific in HPV genotyping (99% concordance between the SPR System and sequence analysis) and can become an effective approach for HPV genotyping in a clinical setting.
