Testing Before The Incubation Period

How to use an iCare Chlamydia test kit – by LT Labs

Every STD test has an advised date from which a test becomes accurate. This is because the bacteria needs enough time to multiply within your body in order for it to reach a detectable level when taking a chlamydia test. For chlamydia this is often 14 days. If you test before that 14 days is over, you may test negative, but you could still pass the bacteria on following your test.

False Positives Vs False Negatives

Because STI tests aren’t perfect, people who design them often have to choose whether it’s better to have more false-positive or more false-negative results. Which is better depends on the severity of the disease and the healthcare provider’s ability to treat it.

Imagine, for example, that a condition has no serious long-term consequences but the treatment itself is grueling. In such cases, a false positive is worse than a false negative because it may expose a person to needless treatments that cause more harm than good.

On the other hand, if an infection is serious and requires immediate treatment, the test would need to be highly sensitive to avoid a false-negative result. Doing so can lead to a missed diagnosis. One such example is an HIV test.

    Sensitivity & Specificity Of The Test

    Definition: Sensitivity is the ability of a test to identify patients that have the disease.

    So if 10 people have a disease and eight of ten of those patients as being positive. Then those are true positives. Sensitivity then is 80%. Rest two of those patients, however, are going to be negative, even though they have the disease and those are called false negatives.

    So when a test that is highly sensitive is good for ruling out disease, when the test is negative .

    Definition:Specificity of the test, is its ability to identify those without the disease.

    10 people dont have any disease. So if 7 out of 10 patients have been tested negative because they dont have the disease and it didnt show in the test as well. So those are truly negative and the Specificity of the test is 70%. So, 3 of them have been indicated as positive, even though they dont have the disease. Those are referred to as False positive.

    So when the test is specific is good at ruling in the disease when test positive

    Who Is At Risk For Chlamydia

    This STD is particularly common in young people. According to a CDC report, chlamydia prevalence among sexually active persons aged 14-24 years is nearly three times the prevalence among those aged 25-39 years. It is more prevalent among young women because at that age the cervix is still developing and is much more susceptible to the bacteria. Additionally, the vagina and cervix provide more surface area than the penis, which makes it easier for women to contract the bacteria.

    Whether chlamydia symptoms are present or not, untreated chlamydia can travel to the upper genital tract and cause serious health problems. In women, chlamydia can lead to pelvic inflammatory disease and cause permanent damage leading to infertility or potentially fatal ectopic pregnancy. In men, untreated cases can lead to epididymitis, which can, but very rarely does, cause sterility.

    In answering this question, it’s important to be clear about which type of chlamydia test is being used. Both the Centers for Disease Control and Prevention and the US Preventative Services Task Force now recommend that nucleic acid amplification tests are used to diagnose chlamydia and also gonorrhea. The CDC has recommended this type of test since 2002.

    Older testing technologies, including culture-based methods, are not as accurate and are also more complicated to perform. A proportion of infections may be missed by older tests.

    The NAAT tests are very accurate, even if — like any test — false results can occasionally occur. If the test says that you do not have chlamydia, this result is accurate for around 99 in every 100 people.

    On the other hand, if the test says that you do have chlamydia, this result is accurate for at least 90 people in every 100. In other words, a few people may be falsely diagnosed with chlamydia when they in fact have another infection or nothing at all.

    Occasional false results may be due to mistakes in taking the specimen and running the test, or because of contamination in the laboratory environment.

    If you have reason to think that a test result is inaccurate, a second test may provide reassurance. If both tests give the same result, it is almost certainly accurate.

    When Should I Get Chlamydia Testing

    • Sex with a new partner
    • More than one sexual partner or a partner who has sex with mutiple people
    • A sex partner diagnosed with an STD

    Testing for chlamydia is more frequently conducted in asymptomatic people in settings where infection rates are high, which often includes correctional facilities, adolescent health clinics, the military, and sexual health clinics.

    Diagnostic chlamydia testing is recommended for anyone with signs or symptoms of this infection. When symptoms do occur, they may not appear until a few weeks after exposure. Signs and symptoms of chlamydia can vary based on the site of infection but may include:

    • Burning during urination
    • Abnormal discharge from the vagina, penis, or rectum
    • Vaginal bleeding after sex or pain during intercourse
    • Pain, tenderness, or swelling in the testicles or scrotum
    • Rectal pain

    Is A Urine Test For Chlamydia Accurate

    How Is Chlamydia Test Done?

    Direct sample: In direct sample, a body fluid sample is collected from the area affected. In adults, such areas are the urethra, cervix, rectum, eye or vagina.

    • For males. To collect a body fluid sample from your rectum or urethra, your physician will insert a cotton swab in the opening of the rectum or urethra. Chlamydia is more likely to be found in a sample collected from urethra in a male if he has not passed urine for at least two hours before collection of the sample.
    • For females. To collect a body fluid sample from your cervix, you will be asked to remove the clothes below your waist and wrap a cloth around it. You have to lie on a table on the back, your feet raised and stirrups supporting them. In this way, your physician can examine your genital area and vagina. They will insert a speculum in your vagina to spread the walls of the vagina gently so that they can look at the inside of the cervix and vagina. A small brush or swab is used to collect samples from your cervix. A self-test is also there for females to collect a body fluid sample from the vagina and take it to the testing lab.
    • To collect body fluid sample from the eye, your physician will brush gently the insides of the upper and lower eyelids using a cotton swab.
    • A throat culture can be done in some rare cases.
