Normalizing Chlamydia ScreeningHow to Talk to Patients

Chlamydia often has no symptoms, but it can cause serious health problems, even without symptoms. If symptoms occur, they may not appear until several weeks after having sex with a partner who has chlamydia.

Even when chlamydia has no symptoms, it can damage a womans reproductive system. Women with symptoms may notice

  • An abnormal vaginal discharge and

Pooled Testing For Chlamydia Trachomatis

Almeria and colleagues stated that pooled testing for CT and NG may be a cost-saving solution to increase screening by simplifying testing procedures and reducing resource burdens. In a systematic review and meta-analysis, these researchers examined the performance of pooled 3-anatomic-site testing for CT and NG in comparison with single-anatomic-site testing. They carried out a systematic literature search in PubMed, Embase, and Web of Science to identify original evaluation studies of the performance of pooled testing for CT and NG infections and identified 14 studies for inclusion. Each study was systematically evaluated for bias. These investigators performed bi-variate fixed-effects and random-effects meta-analyses using a full Bayesian method of the positive percent agreement and negative percent agreement. The combined positive percent agreement for CT was 93.11 % , and the negative percent agreement was 99.44 % . For NG, the combined positive percent agreement was 93.80 % , and the negative percent agreement was 99.73 % . The authors found that pooled 3-anatomic-site tests performed similarly to single-anatomic-site tests for the detection of CT and NG. The pooled 3-anatomic-site tests have the added potential benefit of reduced cost and resource requirement, which could lead to improved testing access and screening uptake.

Nucleic Acid Amplification Test

Chlamydia Test

NAAT tests find out the genetic material of Chlamydia bacteria. A positive test implies that the problem exists. A false-positive test is a false alarm that only appears to detect a disease or condition when infact the disease is not present.

A Polymerase Chain Reaction test is a type of Nucleic Acid Amplification test. It is conducted on a urine sample. The NAA test is a molecular test that detects the genetic material of Chlamydia Trachomatis. It is the most accurate and specific test than those others available for detecting Chlamydia. It can be performed on a vaginal swab on women, or urine from both men and women. Women need not go through any pelvic exam for a NAA test.

How Chlamydia Is Treated

Chlamydia can usually be treated easily with antibiotics.

You may be given a course of doxycycline to take for a week or azithromycin to take once a day for 3 days.

If you have doxycycline, you should not have sex until you and your current sexual partner have finished treatment.

If you have azithromycin, you should wait 7 days after treatment before having sex .

It’s important that your current sexual partner and any other recent sexual partners you have had are also tested and treated to help stop the spread of the infection.

Under-25s who have chlamydia should be offered another test 3 to 6 months after being treated.

This is because young adults who test positive for chlamydia are at increased risk of catching it again.

Sexual health or genitourinary medicine clinics can help you contact your sexual partners.

Either you or the clinic can speak to them, or they can be sent a note advising them to get tested.

The note will not have your name on it, so your confidentiality will be protected.

What Does The Chlamydia Test Involve

The recommended tests for chlamydia are simple, painless and generally very reliable.

They involve sending a sample of cells to a laboratory for analysis. You don’t necessarily have to be examined by a doctor or nurse first and can often collect the sample yourself.

There are two main ways the sample can be collected:

  • urinating into a container this should ideally be done at least 1 hour after you last urinated

The results will normally be available in 7 to 10 days. If there’s a high chance you have chlamydia for example, you have symptoms of the infection or your partner has been diagnosed with it and you’ve had unprotected sex with them you might start treatment before you get your results.

Likelihood of false-negative results is high if you took the test during the window period. To avoid false-negative results, you should repeat the test after the window period. If the initial testing was during the first 12 weeks after possible exposure, the test should be repeated after an extra 12 weeks for more reliable results.6

The recent article by Braun and Provost1 addresses increasing access to health care to improve chlamydia screening. Chlamydia rates are currently estimated at 4.2% among young adults in the general US population, and current recommendations require annual screening for all sexually active females aged 25 years or younger.2 The Healthy People 2010 goals regarding chlamydia are: To reduce the proportion of adolescents and young adults with Chlamydia trachomatis infections to 3% by 2010, and Increase the proportion of sexually active females aged 24 years and under who are screened annually for genital Chlamydia infections.3 In their article, Braun and Provost explored the effects of broadening access to health care on chlamydia screening rates.

Braun and Provost’s article is an excellent starting point for further discussions on policy that can improve access to sexual health care for both male and female adolescent patients. Further research is needed to investigate health care utilization of adolescent males in school-based health clinics. Most important, future research is needed on chlamydia screening programs directed toward adolescent and young adult males in hopes of generalizing screening guidelines and policies.

How Will I Get My Results

Your doctor will call you with the results of your test. Be sure you give your doctor your preferred phone number where you can have privacy, such as a mobile phone number. If you dont want them to leave you a voicemail, be sure you tell them before you leave your appointment.

A urine test is much faster to analyze. Your doctor should be able to tell you the results on the same day as your appointment. The downside is that urine tests may not be as accurate as traditional swab testing.

However, urine testing may be more suitable for people assigned male at birth. Its also used for more advanced signs of chlamydia, as your body will have a greater number of bacteria to detect at this stage.

What Does The Test Result Mean

SELFCheck female chlamydia test kit

A positive test indicates you have an active chlamydia infection that requires treatment with antibiotics.

A negative test means only that there is no evidence of infection at the time of the test. If you are at an increased risk, it is important that you have screening tests performed yearly to check for possible infection, especially since re-infection is common, particularly among teenagers.

If you are infected, your sexual partner should be tested and treated as well.

    Accuracy Of Screening Tests And Risk Assessment

    The USPSTF found convincing evidence that clinicians could identify sexually active women at increased risk for chlamydial and gonococcal infections. It found adequate evidence that clinicians could identify sexually active men at increased risk for chlamydial and gonococcal infections. Seven new fair-quality studies with more than 93,000 participants were included in the analysis.34-39 In asymptomatic individuals, 3 studies with 71,636 participants that used a risk score to identify persons with chlamydial or gonococcal infections reported an area under the curve of 0.64 to 0.73.34-36 One study showed that age alone had accuracy similar to that for the use of more extensive risk criteria.39

    Is Chlamydia Serious

    What tests are necessary for diagnosis of Chlamydial infection? – Dr. Teena S Thomas

    Although chlamydia does not usually cause any symptoms and can normally be treated with a short course of antibiotics, it can be serious if it’s not treated early on.

    If left untreated, the infection can spread to other parts of your body and lead to long-term health problems, especially in women.

    In women, untreated chlamydia can cause pelvic inflammatory disease , ectopic pregnancy and infertility.

    In men, in rare cases, chlamydia can spread to the testicles and epididymis , causing them to become painful and swollen. This is known as epididymitis or epididymo-orchitis .

    It can also sometimes cause reactive arthritis in men and women.

    This is why it’s important to get tested and treated as soon as possible if you think you might have chlamydia.

    Testing for chlamydia is done with a urine test or a swab test.

    You do not always need a physical examination by a nurse or doctor.

    Anyone can get a free and confidential chlamydia test at a sexual health clinic, a genitourinary medicine clinic or a GP surgery.

    In England, if you’re a woman under 25 years old, you may be offered a chlamydia test when you visit some health services, for example a pharmacy or GP. This offer is part of the National Chlamydia Screening Programme .

    If you’re offered a chlamydia test you should consider taking it.

    If you’re a woman, sexually active and under 25 in England, it’s recommended that you have a chlamydia test once a year, and when you have sex with new or casual partners.

    When Is It Ordered


    Because many infected people do not have any noticeable symptoms, a number of health organizations recommend regular chlamydia screening for certain people:


    All sexually active women younger than age 25 and sexually active women age 25 and older who are at increased risk should get yearly screening for chlamydia, according to the Centers for Disease Control and Prevention and the American College of Obstetricians and Gynecologists . The U.S. Preventive Services Task Force and the American Academy of Pediatrics also recommend routine screening for these women .

    Examples of risk factors for chlamydia infection include:

  • Previous chlamydia infections, even if you have been treated
  • Having STDs, especially HIV
  • Having new or multiple sex partners
  • Having a sex partner diagnosed with an STD
  • Using condoms inconsistently
  • Exchanging sex for money or drugs
  • Using illegal drugs
  • Living in a detention facility
  • For pregnant women, the CDC recommends screening for chlamydia during the first trimester or first prenatal visit. For women younger than age 25 or at increased risk of infection, testing is repeated in the third trimester. Pregnant women diagnosed with chlamydia should be retested about 3 months after completing treatment.


    Chlamydia testing may also be done when your sex partner has been diagnosed with chlamydia or when you have signs and symptoms of chlamydia.

    For women, if symptoms occur, they may include:

    For men, symptoms may include:

    Best Practice : Use The Least Invasive High

    According to the 2015 STD Treatment Guidelines from CDC, chlamydia can be diagnosed in women by testing clinician-collected, self-collected vaginal swabs, or urine specimens. Systems should be developed to make all of these options available, and all efforts should be made to use the least invasive, high-quality test that is acceptable to, and convenient for, the client.

    How Does Evidence Fit With Biological Understanding

    Chlamydial and gonococcal infections are often asymptomatic in women. Untreated infections may progress to PID-related complications such as chronic pelvic pain, ectopic pregnancy, or infertility. Infections may also be transmitted to sex partners and newborn children. Accurate screening tests and effective antibiotic treatments are available for chlamydia and gonorrhea.

    In men, gonococcal infections are more commonly symptomatic compared with women. Serious complications from infection are less common in men.

    Studies on assessing risk and for whom screening may be most effective are a high priority.

    The CDC recommends annual chlamydia and gonorrhea testing in all sexually active women younger than 25 years and in older women at increased risk of infection . It also recommends screening for both infections in pregnant women younger than 25 years and in older pregnant women at increased risk for infection during their first prenatal visit and again during their third trimester if risk remains high.16

    The American Academy of Family Physicians follows the 2014 USPSTF chlamydia and gonorrhea screening recommendations.58 The American Academy of Pediatrics recommendations align with the CDC guidelines.59
