Four Tests, One Vial
Pap test, HPV, Chlamydia and Gonorrhea
Medco Forum, May 2002
AmeriPath is now offering chlamydia and gonorrhea testing.
We are one of the first laboratories to offer this test from
the Thin-layer Pap Test vial, providing you with the ability
to order four tests from one vial: Pap test, HPV, chlamydia
and gonorrhea.
Chlamydia and gonorrhea are two of the most common sexually
transmitted diseases in the United States, infecting approximately
three to five million Americans annually. Unfortunately, there
are often no symptoms and, if left untreated, these infections
may lead to severe complications. Many professional organizations,
such as the American College of Obstetricians and Gynecologists
(ACOG), recommend that the following patient populations be
screened for chlamydia and gonorrhea:
· All patients under the age of 25 (annual screening);
·
All other patients who are considered high-risk:
- History of multiple sexual partners or a sexual partner with
multiple contacts
- Sexual contact with persons with culture-proven STDs
- History of repeated episodes of STDs, and
- Attendance at clinics for STDs
In addition, all obstetrics patients should be screened in
order to prevent transmitting the disease to their infant
during birth.
AmeriPath is using PCR-based testing; specifically, the Roche
Cobas Amplicor Assay. This test method will detect chlamydia
and gonorrhea by using a multiplex PCR to amplify sequences
specific to each disease. This PCR-based method provides increased
sensitivity and specificity in comparison with other previously
used methodologies, such as GenProbe, Abbot LCx and cell cultures.
The following chart depicts sensitivity and specificity data
from a study published in the Journal of Clinical Microbiology.

AmeriPath is making this testing easy for you. In addition
to the Pap test and HPV test, you can order chlamydia and gonorrhea
testing directly from the Thin-Layer Pap test vial. This means
you only have to collect one sample. More importantly, you
can send your Pap tests, HPV, chlamydia, gonorrhea samples
and your biopsies to the same laboratory: AmeriPath.
The diagnostic quality available at AmeriPath is unparalleled
in the industry. Our ASCUS rate remains less than 5%, compared
with the 10-15% average maintained by national clinical laboratories.
Our 77 board-certified cytopathologists pool their medical
expertise when consulting on unique or difficult cases and
provide personal consultations regarding patient treatment
plans and disease management. We have extensive managed-care
coverage, superior turnaround times for Pap tests and for biopsies,
as well as informative patient education materials. Our enhanced
pathology reports include color photomicrographs, a cervical
map, and a cytology history chart. In addition to all of this,
we have a new program to notify your patients of normal Pap
test results to save you time and money.
