Region IIInfertility Prevention ProjectNew York City, New YorkMay 31, 2006 Supplemental Testing (Repeat Testing) Alternate Specimens (vaginal, rectal and pharyngeal) CDC/APHL 2004 National STD Laboratory Survey
Supplemental Testing • Zanto, et.al.; Region VIII • Gen-Probe ACT and AGC reagents can be used effectively as a supplemental test • Supplemental testing (repeat Gen-Probe AC2) is equally as effective as an alternate target (ACT) • Reporting the initial positive AC2 screening result in this low prevalence (7.5%) population had a greater than 95% positive predictive value (PPV) for CT • Reporting the initial positive AC2 screening result in this low prevalence (1.6%) population had a 91.3% PPV for GC • Based on these PPVs, supplemental or repeat testing need not be routinely performed with NAAT screening, resulting in cost savings.
Alternate Specimens (vaginal, rectal and pharyngeal) • References • California Action Coalition (CAA) • CDC/FDA – Dr. Papp • Workshop NIAID (June 28-29, 2006)
Methods: Laboratory Survey • Surveyed 162 public, private and university laboratories in February 2005 • All members of the Association of Public Health Laboratories (APHL) • All laboratories that participate in CDC’s Regional Infertility Prevention Project • An on-line survey was developed that requested the following information for calendar year 2004: • Volume and type of testing for chlamydia and gonorrhea • Volume and type of testing for HSV, Trichomonas, Syphilis, Bacterial Vaginosis, HPV, and Pap Smears
Methods: Laboratory Survey • An e-mail was sent to each laboratory director with link to survey • 34/162 e-mails not successfully transmitted; corrected some addresses and resent. • 25/34 e-mails failed to transmit again; FAXes sent to those lab directors with the link to the survey. • Asked for responses in two weeks • Non-responder follow-up • 2 follow-up e-mails were sent at the end of weeks 1 & 2 • Additional e-mails and phone calls were made after 3 weeks
Results: Laboratory Survey Response • Survey was completed by 119 laboratories (73% response rate) • Responding laboratories were from 49 states and two U.S. territories: • 51% state laboratories (n=61) • 34% county laboratories (n=41) • 10% city laboratories (n=12) • 2% U.S. territory laboratories (n=2) • 2% university laboratories (n=2) • 1% private laboratories (n=1) • Focused on public health laboratories (95% of responding laboratories) • Survey was completed by 114 of 144 public health laboratories (79% response rate)

Laboratory Survey: Next Steps • Compiled and distributed survey results • Available via the APHL website • Distributed to IPP Coordinators (Word) • Chlamydia and Gonorrhea data was presented in a poster at ISSTDR, July 2005 • Collected information from test kit manufacturers • Number of CT & GC test kits sold in 2004 • % or # sold to public health laboratories • Prepared and submitted manuscript on survey results to JSTD (July)
Male Chlamydia Screening ConsultationMarch 28-29, 2006 • Urine is the specimen of choice when screening males (NAATS) • Leukocyte Esterase Test (LET) is not recommended in any venue. • Pooling should strongly be considered in low prevalence populations (<10%).
