How To Interpret Chlamydia Test Results

What is Chlamydia? Symptoms and Testing

Lab test results may be positive, negative or in some case inconclusive. A positive test result means the infection is there and the person is suffering from Chlamydia infections. So the person should go for treatment as advised by the doctor. Negative test interprets bacteria is not found and he/she is normal. Sometimes it also means that bacteria are at a very low amount and impact of it is not seen. But if there will be an increment in that then only it will start impacting. Sometimes test result gives inconclusive results. It happens when test result does not clearly indicate whether it is positive or negative.

How to Conclude Chlamydia Test Result?

There is a very slight chance of false test result. NAAT accuracy result is almost 100% whereas for Chlamydia culture it is 80%. This test is very necessary to be conducted because it gives accurate results. A person should conduct this test in identified lab only and certified person should see the result. An impact of this infection is huge at later stages. So, diagnosis of this is necessary so that person does not suffer from this infection later and it is easy to curb it at earlier stages later on it becomes difficult to curb its impact.

This is how, you can read your Chlamydia Test result without any doctor guideline. However, I would suggest you to consult doctor to get proper guideline.

If symptoms do not resolve after a few days, consult your healthcare provider. You should refrain from having sex until you have completed your treatment and should be re-tested three months after treatment.

What To Expect From A Chlamydia Blood Test

Chlamydia Tests – Diagnosing Sexually Transmitted Bacterial Infection

When the body is infected by the chlamydia trachomatis bacteria, it develops antibodies called IgM antibodies that circulate in the blood. This chlamydia blood test identifies if these IgM antibodies are in the blood to determine if there is a current chlamydia infection

It should be noted that chlamydia is not a bloodborne disease. This chlamydia blood test should not be used to diagnose chlamydia infection of the urogenital area . This chlamydia test helps determine if a chlamydia infection is affecting non-genital regions of the body, for example, chlamydia trachomatis can cause conjunctivitis . If youre interested in getting tested to diagnose a chlamydia infection of the urogenital area, consider a urine chlamydia test.

Advantages Disadvantages And Availability Of Select C Pneumoniae Diagnostic Methods

C. pneumoniae

Advantages, disadvantages, and availability of select diagnostic methods

  • Provides information in time for a treatment decision
  • Variety of acceptable specimen types1
  • Expensive
  • Requires specialized expertise and equipment
  • Clinical laboratories: real-time PCR using validated laboratory-developed test or commercially available FDA cleared multi-pathogen detection systems3
  • CDC: Multiplex real-time PCR laboratory-developed test2
  • Real-time PCR is the preferred method for the diagnosis of an acute C. pneumoniae infection

1 Acceptable specimen types vary by system.

2 Culture can be performed at CDC but is not used for routine diagnostic purposes.

3 State and local departments of public health may also offer these diagnostic tests for the detection of C. pneumoniae.

4 CF is not recommended for diagnosis of acute C. pneumoniae infection because of cross-reactivity with other Chlamydia species and other enteric bacteria. Also, the sensitivity for detecting reinfection is low. Whole-inclusion fluorescence tests are also not species-specific and have not been widely evaluated. EIA is not a recommended diagnostic method because of low sensitivity and specificity.

5 MIF is the only species-specific antibody test available that can measure isotype-specific antibody titers to all Chlamydia species simultaneously. However, MIF testing is technically complex and interpretation is subjective.

Causes Of A Positive Chlamydia Test

Certain situations can give false positive result on a blood test. Presence of antibodies against the bacteria may not always indicate a current infection. It can indicate a previous infection but cannot determine if the patient has infection at the time of the test. This may give a false positive result on the test.

Rectal swabs and oral swabs may also be considered for those who have receptive anal sex or unprotected oral sex.

While neither rectal nor oral swabs are currently approved for the detection of chlamydia, research suggests that doing these extragenital tests is important.

For example, a 2017 study found that among men who have sex with men , 13% had a rectal chlamydia infection but only 3.4% had a positive urethral swab. In women in an urban setting in the United States, 3.7% were found to have an extragenital infection. Those under the age of 18 had the highest incidence of extragenital infection.

  • 75% of women and 50% of men do not experience any symptoms.
  • If a person develops chlamydia symptoms, they usually occur 7-21 days after exposure.
  • the symptoms of chlamydia are similar to gonorrhea, so the two diseases are often confused.
  • All Ages and Sexes

    If you are a woman, a sample may be taken from your cervix. For this procedure, you will lie on your back on an exam table, with your knees bent. You will rest your feet in supports called stirrups. Your health care provider will use a plastic or metal instrument called a speculum to open the vagina, so the cervix can be seen. Your provider will then use a soft brush or plastic spatula to collect the sample.

    If you are a man, your provider may take a swab from the opening of your urethra.

    Are Test Results Accurate

    Although chlamydia testing is an important method of finding and treating this common STD, test results could be impacted by the following:

    • The use of antibiotics within several days before testing
    • Urinating within one hour of sample collection
    • Vaginal douching within 24 hours of testing
    • Improper sample collection
    • Contamination of rectal samples with fecal matter

    What Is The Procedure Of The Chlamydia Test

    There are no special preparations required for the chlamydia test. However, it is important to inform your doctor if you are taking any kind of medication. It is also advised not to apply any vaginal creams as it may affect the test results. Normally, Menstruation does not affect the test results. So you can also take the test during your menstrual cycle.

    The chlamydia test is normally done on the urine samples of the patient. It is the most effective technique to detect the infection if any. You should not urinate at least 2 hours prior to the test. Only the initial urine stream should be collected in the tube. The sample will be then sent to the laboratory for further testing.

    Sometimes a swab may be used to collect the samples, such as a vaginal swab, rectal swab, urethral swab, endocervical swab, etc.

    Chlamydia tests can also be done on the blood samples. But is not widely used as the results may not show the presence of chlamydia at the time of the test.

    What To Think About

    • If a chlamydia infection is suspected, do not have sexual intercourse until the test results have come back. If you have a chlamydia infection, do not have sexual intercourse for 7 days after the start of treatment. Your sex partner should also be treated for a chlamydia infection so that you don’t get reinfected and so that others don’t get infected.
    • Only one laboratory test is needed to diagnose chlamydia. Your doctor can choose which test to use.
    • Screening for and treating chlamydia can help prevent pelvic inflammatory disease . To learn more about the treatment of a chlamydia infection, see the topic Chlamydia.
    • Other sexually transmitted infections may be present at the same time as chlamydia. So it is important to be tested and treated for all STIs. Chlamydia as well as other STIs can also increase the chance of getting human immunodeficiency virus . An HIV test may be offered at the same time as a test for chlamydia or other STIs.

    Isolation Of C Trachomatis In Cell Culture

    New chlamydia test offers rapid, pain

    Established cell lines for isolation of C. trachomatis include Mc Coy, HeLa 229 or Buffalo Green Monkey Kidney cells. Swabs from different anatomical sites are suitable specimens for culture but must be collected using special devices and transport media . Specimens were centrifuged onto confluent cell monolayer and analyzed for the development of characteristic intracytoplasmatic inclusions after 4872 h by staining with Giemsa, iodine, or fluorescence labelled antibodies to chlamydial antigens . When using MOMP-specific antibodies for staining cell culture, detection is highly specific , and thus it was long considered the reference test for CT detection. On the other hand, as culture depends on vital organisms the detection rate is at best 60%80%, even when performed in laboratories with experienced technicians . Sensitivity of culture may be impaired by inadequate specimen collection, storage and transport, toxic substances in clinical specimens and overgrowth of cell cultures by commensal microbes. Additional disadvantages are represented by the extended turn-around time, labor intensity and difficulties in standardization. Thus, cell culture is rarely used nowadays in diagnostic laboratories, but the methodology is still needed, at least in some reference laboratories, to monitor antibiotic susceptibility and changes of virulence, or when a test with the highest specificity is required as in case of suspected sexual assault.

So, several other tests are often ordered along with this test to confirm the diagnosis of chlamydia infection.

    Enzyme linked immunosorbent assay , Enzyme immunoassay, cell culture, nucleic acid amplification tests , detection of chlamydia by fluorescent antibody test method, and swabs samples test, are some of the tests ordered to confirm the diagnosis of the infection.

    Other STD detection tests like gonorrhea, HIV/AIDS, Hepatitis B, Trichomoniasis, and Syphilis may also be ordered as certain signs and symptoms shown by these STDs are similar and can be confusing.

    Retesting for chlamydia 3 months after the treatment is recommended. Screening for Chlamydia trachomatis specific antibodies is valuable in diagnosing asymptomatic pelvic inflammatory disease and tubal block.
