Hopkins researchers develop quick, low-cost test for STD

"Researchers at the Johns Hopkins University have developed a low-cost diagnostic tool, slightly larger than a coffee mug, that detects chlamydia within 30 minutes.

Scientists hope the apparatus, unofficially called mobiLab, will improve screening for the common and often symptomless sexually transmitted disease that, if left untreated, can cause permanent damage to a woman's reproductive system and lead to fatal ectopic pregnancies.

The prototype, developed by researchers in the Hopkins Department of Biomedical Engineering, is made of a disposable cartridge for a genital swab sample and a heating unit that incubates the DNA to facilitate a reaction. The test results are delivered to and processed by a mobile app on a smartphone connected to the battery-powered device.

MobiLab is "the first demonstration of a cellphone-based DNA test of chlamydia," said researcher Jeff Wang, a Hopkins mechanical and biomedical engineering professor..."

"...After the defendant’s arrest in July, the government obtained a urine sample from him, which was sent to the Johns Hopkins University’s STD Laboratory. The lab results showed that he possessed Trichomonas, the same STD he transferred to the child.... [Acting U.S. Attorney Cohen] further commended the vital assistance provided by Dr. Jonathan Zenilman, Dr. Charlotte Gaydos, and Laboratory Manager Laura Dize from the Infectious Diseases Department at Johns Hopkins University..."

Chlamydia screening 'easi
er and cheaper' with new DNA smartphone test
By Honor Whiteman, July 30, 2015

“Researchers have created a simple smartphone DNA test that they say can accurately detect chlamydia - the most commonly reported sexually transmitted infection in the US.

Jeff Tza-Huei Wang, PhD, from Johns Hopkins University in Baltimore, MD, and colleagues say the test - called mobiLab - could reduce the prevalence of chlamydia by making testing for the disease cheaper and easier.

[Study co-author Dong Jin Shin] recently presented study findings detailing the test's accuracy at the 2015 American Association for Clinical Chemistry (AACC) Annual Meeting & Clinical Lab Expo in Atlanta, GA…”

2013 Innovator of the Year Award

Congratulations to Professor Chris D. Geddes and the Institute of Fluorescence (IoF) who have recently been named winners of the 2013 Innovator of the Year Award by the Daily Record. Dr. Geddes and the IoF have won the award for their development of a very rapid and low cost test for the detection of sexually transmitted infections (STIs). Typically molecular diagnostics for STIs can take as long as 48 hours, during which time further transmission of the infection can occur. The IoF's technology can detect the presence of an STI within 8 minutes, allowing a real-time point-of-care test to be realized; patients presenting with STI-like symptoms in a healthcare setting can be diagnosed and potentially treated on-site. The new test costs less than $2.00 per swab, making the test attractive for downstream commercialization and clinical use.

In addition to Dr. Geddes, IoF/Chemistry graduate student Johan Melendez worked on the project as part of his thesis. The clinical validation of the technology has recently been reported in the Journal of Clinical Microbiology.

Do-It-Yourself STD Tests
Hosted by Josh Zepps (originally aired on October 23, 2013)

Do-it-yourself STD tests are currently available, and more of them are expected to hit the market soon. How do these products work, and what are the public health and bioethical issues surrounding them? Charlotte Gaydos DrPH, MPH, MS (Baltimore, MD) Professor in the Division of Infectious Diseases at Johns Hopkins University School of Medicine is an on-air guest on this segment of HUFFPOST LIVE.

Hopkins pushes for responsible sex
By Andrea Michalowsky - November 15, 2012

"...Taking note of these steep prices and the lack of relevant resources available to Baltimore’s youth, Dr. Charlotte Gaydos, a professor in the Division of Infectious Diseases at the School of Medicine, launched, a web-based free testing service that came online in 2004. Via the website, people in Maryland can request a home STI testing kit. These kits allow the recipient to take a sample and mail it free of charge to a testing site. They are then informed of the results via phone, email or text message.

Started as a research project at Hopkins, IWantTheKit is the only service of its kind. Gaydos emphasizes the importance of encouraging people to take responsibility for their sexual health..."

Comparative Effectiveness of POC Tests for Chlamydia in a Clinic Setting

Commentary by Charlotte Gaydos, MS, MPH, DrPH who describes how any promising new chlamydia point-of-care (POC) test is likely to be cost-effective compared with traditional nucleic acid amplification tests (NAAT) in a clinic when specified characteristics are met.

STD Home Tests Avoid Embarrassment
By Erin Allday - April 28, 2012

Young women in four Bay Area counties can now test themselves at home for sexually transmitted infections, and then get the results and any needed prescriptions without ever visiting a doctor's office or clinic. The home tests are part of a pilot project designed to give women who have had unprotected sex, or are just curious about their health status, a convenient, cost-effective and potentially less embarrassing way to get screened for STDs, public health officials said.

... Women send the sample to a lab at Johns Hopkins University that specializes in processing home tests, and a few days later they get a text or e-mail message telling them their results are available online.

Social Media vs. Social Disease

By Patricia McAdams, Special Issue 2012

With 19 million new sexually transmitted infections (STIs) each year in the U.S., notifying partners is a crucial public health responsibility. But financially strapped local health departments often lack the resources to personally notify partners of an infected person.

Can tech pick up the slack?

Charlotte Gaydos, DrPH '93, MPH, MS, and Jessica Ladd, MPH '11, decided to find out. They developed a survey, targeted at teens and young adults, to learn whether anonymous emails, e-cards, text messages or letters would be an acceptable tool for sending and receiving partner notifications regarding a possible STI.

The survey was posted as a Facebook Event for two weeks in early September, successfully recruiting more than 500 individuals. Of these, 343 met the criteria for the study.

Dr. Charlotte Gaydos on STD Point of Care Development
Uploaded by  on Dec 24, 2011

"I shot this video knowing it would be an educational tool for professionals involved in development of point-of-care technologies for sexually transmitted diseases; so in other words, it was never intended for general public audiences, although the public could learn a lot from the information presented here. Ideas for basic content of this video were developed by me (Jude Gustafson) and Dr. Brenda Korte of the National Institute of Biomedical Imaging and Bioengineering. Dr. Gaydos, an internationally recognized expert in her field, was videotaped at her office at the Johns Hopkins Center for Point-of-Care Tests for STDs in August of 2011."

Mail-order STD Testing & POWER Teen Clinic
Submitted by KTD, Producer Sarah Gonzales, on October 5, 2011

Alaska flyer

Whether or not teens make the choice to engage in safe sexual relationships, there is always the risk of contracting a sexually transmitted disease after intercourse. Getting tested and treated for a STD can be as easy as visiting a local public health clinic, but what if you're too shy to be seen in person, live in an area not served by a local clinic or simply can't get a ride?

Johns Hopkins University and the Centers for Disease Control and Prevention introduced a mail-order STD test kit in 2004 on the east coast to much success among teens and young people. Now this same program has come to Alaska. You can order a kit at, and visit to learn more about sexual health, testing and resources in Alaska.

Listen as KTD Producer Sarah Gonzales interviews Dr. Charlotte Gaydos. The story is now posted on their website and the audio can be accessed directly from a link on the page.
