Two different tests are available known as Cervista HPV 1618 and Cervista HPV HR. About 60 HPV types penetrating into the human cells can cause appearance of papillomas warts most commonly on hands or feet.

If you have a non-HPV 1618 result intermediate risk.

What is hpv not 16/18 detected. The Cervista test is used to diagnose the presence of DNA from the high-risk HPVs in cervical samples. Most laboratories in the United States use a standard set of terms called the Bethesda System to report Pap test results. Women who have had the HPV vaccine still need to have a Cervical Screening Test every five years.

Persistent HPV 16 and 18 infections markedly increase in the risk of cervical. It is important that you have a further follow-up because you may be at a high risk of developing cervical cancer. Several HPV tests are specific for HPV16 and HPV18the types that cause most cervical cancers.

HPV 16 and 18 are the most virulent. Genotyping solely for HPV-1618 would miss the majority of patients with LSIL who progress to high-grade squamous intraepithelial lesions. HPV 16 and HPV 18 are together responsible for approximately 70.

HPV 18 is another high-risk type of HPV. No HPV 16 or 18 DNA was detected in the blood of 32 women with pre-cursor cervical lesions or normal cervical pathology but who had cervical HPV 16 or 18 infections. Infection with non-1618 HR-HPV genotypes but not with HPV-1618 genotypes was a strong predictor of the persistence and progression of cervical disease upon follow-up.

Data suggest that certain HPV genotypes types eg HPV types 16 18 31 33 35 39 45 51 52 56 58 59 66 and 68 are considered high. Not detected result is consistent with the absence of high-risk HPV E6E7 mRNA a level of HPV mRNA below the detection limit of the assay or presence of a genotype other than those listed above. You may still be recommended for a colposcopy if abnormal cells are detected.

HPV 16 and 18 have been shown to significantly increase the risk of cervical cancer as well as genital cancers. A negative high-risk HPV result does not. Cervista HPV 1618 is used to diagnose the presence of DNA from the two most common HPV types associated with cancer HPV 16 and 18.

The results indicate that HPV DNA can be detected in the blood of women with more advanced cervical. While the HPV vaccine protects against certain high risk types of HPV including 16 and 18 it does not protect against all types of HPV. A woman may want to ask her provider for specific information about her Pap and HPV test results and what these results mean.

It suggests a low risk of cervical cancer. Yes there is a vaccine for some types of HPV. Luckily they are not as widespread as the others are.

High-risk mucosal genital HPV types. Sensitivity may be affected by specimen collection methods stage of infection and the presence of interfering substances. Those cases will be referred for a colposcopy.

An intermediate risk result means an HPV infection not 1618 was detected. This test detects high-risk HPV types 16 18 31 33 35 39 45 51 52 56 58 59 66 and 68 and differentiates HPV 16 and 18 associated with cervical cancer and its precursor lesions. Both high-risk HPV genotypes especially HPV-16 and 18 as well as persistent HPV infection eg an infection that is not cleared by the patients immune system over time are associated with an increased chance of progressing to high-grade CIN and invasive cancer.

Pooled HR-HPV tests provide a better predictive value than HPV-1618. Genotyping solely for HPV-1618 would miss the majority of patients with LSIL who progress. One of 77 women with normal cervical pathology and no cervical HPV infection was positive for HPV 16 DNA in her blood.

In women warts may appear in areas that arent always noticed such as the cervix and vagina. HPV 16 and 18 are known to be high-risk HPV strains because they cause about 75 of cervical cancers. A reflex LBC conducted on the same sample showed that the patient has negative possible low-grade squamous intraepithelial lesion LSIL or LSIL abnormal cervical cells.

Results should be interpreted in conjunction with other available laboratory and clinical data. They are two of the main causes of cervical cell cancer Dr Farrell says. Your test results show either HPV infection with types 16 andor 18 high grade cell changes on your cervix or persistent infection with one of the other high-risk HPV types not 1618.

Like HPV 16 it doesnt typically cause symptoms but it can lead to cervical cancer. Infection with HPV-1618 genotypes was not significantly associated with the persistence or progression of cervical lesions. Low-risk genital HPV infection can cause cauliflower-shaped warts on or around the genitals and anus of both men and women.

Infection with non-1618 HR-HPV genotypes but not with HPV-1618 genotypes was a strong predictor of the persistence and progression of cervical disease upon follow-up. An intermediate risk result is not associated with high-grade cell changes that require treatment.
