Description

Introduction

Over 130 HPV types have been documented in the literature, approximately 40 of which infect the anogenital area and are sexually transmitted. Persistent anogenital high-risk HPV infection is associated with the majority of cervical cancers. Cervical cancer is highly preventable when cytological and HPV screening programs are employed to facilitate early detection and treatment of pre-cancerous lesions. Of the sexually transmitted HPV genotypes, 14 (HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68) are considered high risk as they lead to cervical cancer or anogenital warts. In addition, HPV types 6 and 11 are considered low risk for cervical cancer. However, they are the cause of 90% of all cases of genital warts as well as respiratory papillomatosis.

Principle of Assay

The crb® HPV Complete qPCR uses probe-based qPCR technology to detect HPV with high specificity. Each sequence-specific probe contains a 5’ fluorophore and a 3’ quencher. On its own, the probe’s 3’ quencher effectively absorbs the emission from the nearby 5’ fluorophore so that no net fluorescence is detected. During PCR amplification, the probe binds to its specific target template. While replicating the DNA sample, the PCR Taq Polymerase’s 5’ to 3’ exonuclease activity also hydrolyzes the probe, releasing a free-floating 5’ fluorophore that is detectable by the qPCR machine and can be translated into an amplification plot. This HPV Complete qPCR kit identifies 14 types of high-risk HPV, 2 types of low-risk HPV, and a human ACTIN control using 4 fluorescent channels in one tube: ROX, FAM, HEX, and Cy5. As a result, this kit can not only detect the 14 high-risk HPV types and 2 low-risk HPV types, it is also capable of distinguishing HPV 16 and 18 from all the other types. The internal control, human ACTIN, indicates the quality of extracted DNA.

 

 

The crb® HPV Complete qPCR  is a qualitative in vitro diagnostic test that detects all 14 high risk HPV subtypes: HPV 31, HPV 33, HPV 35, HPV 39, HPV 45, HPV 51, HPV 52, HPV 56, HPV 58, HPV 59, HPV 66, and HPV 68) at clinically relevant infection levels from cervical swab specimens.

Analytical Sensitivity

130 copies/reaction

Analytical Specificity

 

Cross reaction among these 16 HPV types was not observed. A panel of bacteria, fungi, and viruses commonly found in the female anogenital tract were tested with the crb® HPV Complete qPCR Kit to assess potential cross-reactivity. The pathogens tested include: Candida albicans, Proteus vulgaris, Corynebacterium pseudodiptheriticum, Staphylococcus aureus, Enterococcus faecalis, Staphylococcus epidermidis, Escherichia coli, Streptococcus mitis, Lactobacillus acidophilus, Streptococcus pyogenes, Herpes simplex virus, type 1 and 2 (HSV-1 and 2), Chlamydia trachomatis, Neisseria gonorrhoeae, Human Immunodeficiency Virus type 1 (HIV-1 pol and env regions), and Mycoplasma hominis. Negative results were obtained from all the above-mentioned organisms.

Reproducibility

 

Reproducibility of the crb® HPV Complete qPCR was assessed at two external sites using a panel of HPV positive and negative cultured cells and HPV positive and negative cervical specimens. DNA was extracted from 500 μl of cervical samples or cultured cells suspended in Specimen Transportation Medium. The DNA was extracted using the sample prep solution included in this Kit. DNA was extracted from sixteen samples and tested with crb® HPV Complete qPCR Kit at two sites on five non-consecutive days within a two-week time period. Two lots of crb® HPV Complete qPCR Kits were used across the two sites for the study. The total number of measurements for each sample was 20 (2 sites x 5 days x 2 lots x 1 run per day). The results showed that the coefficient of variation (CV) for the kit performance was less than 5% among different product lots and different operators.
