  • Monthly list of all abnormal cases are provided for each physician.
  • Retrospective review of prior negative PAP smears for all high grade cases.
  • Our internal quality assurance program provides follow up for all patients with abnormal PAP smears/follow up letters for all abnormal PAP results, correlation cases with histology, HPV testing, and follow up treatment for each patient.

DPMG Offers You a Choice

DPMG appreciates that not every practice prefers just one method, so as your full-service laboratory, we want to provide both choices for liquid-based Pap test collection as well conventional Pap slides.
Both tests DPMG offers are FDA approved, and liquid-based Pap tests have shown to identify higher rates of abnormalities compared to conventional Pap slides.


Computer-Assisted Screening

DPMG offers the ThinPrep® Imaging System with Dual ReviewTM, which combines revolutionary imaging technology with human interpretive expertise for a more accurate diagnosis. Studies have shown that using the Imager reduces the false negative fraction by 39% over manual screening. To assure quality control, 90% of all imaged slides are manually reviewed.


Getting the Most Out of Your Pap

All tests are performed in-house allowing for timely and accurate results


HPV Testing DPMG offers HPV testing using the Aptima HPV assay, targeting E6/E7 mRNA of 14 high-risk HPV types. The presence of E6/E7 mRNA is more indicative of the HPV infection destined to lead to disease rather than the transient HPV infections.Together the Pap and HPV test offer more reliable and accurate results. Why is it important to do HPV screening with a Pap for women age 30 and older? While the incidence of onocogenic HPV infection declines with age, the risk of cervical cancer from a persistent infection increases. For women age 30 and older, HPV testing helps identify those most at risk.

  • 1 out of 6 women (15%) who are HPV positive and Pap negative will develop ASCU+ within 5 years

HPV Genotyping

DPMG offers HPV Genotyping types 16, 18/45. These types are found in up to 75% of all squamous carcinomas and up to 94% of all cervical adenocarcinomas.

Genotyping for types 16/18 is beneficial for patient management and recommended by ASCCP. You can use this test to further triage for ASCUS, LSIL or for patients who are 30 years of age or older, with negative cytology results who test positive for high-risk HPV.

Other Molecular Testing Using Convenient Testing Options

Chlamydia, Gonorrhea and Trichomonas testing can be performed out of the Pap vial, by using an Aptima swab collection device or Aptima urine transport tube. Annual screening is recommended for all sexually active women 25 years old or younger, and other women at increased risk of infection. This is recommended by the CDC, AMA, and ACOG.

Vaginitis testing for the detection of five common Candida species, Gardnerella vaginitis and Lactobacillus species and Trichomoniasis, can also be performed by using swab collection devices. This test helps identify mixed infections with objective, accurate results

Mycoplasma genitalium can be performed by using the Aptima swab collection devices or Aptima urine transport tube. The CDC recommends this test for women with recurrent cervicitis and considered among women with PID.

Rectal and throat Chlamydia and Gonorrhea can be performed using the Aptima swab collection device.

HSV 1 & 2 using the Aptima Multitest Swab Specimen Collection Kit on anogenital skin lesions.
