What is Chlamydia trachomatis IgG?
Chlamydia trachomatis IgG antibody testing (CAT) has been used as a screening test for tubal factor infertility (TFI), but as the CAT is only a marker of a past exposure to C. trachomatis and not of late sequelae, the positive predictive value (PPV) of the test is low.
Is Chlamydia trachomatis Gram positive or negative?
The gram-negative obligate intracellular bacterium Chlamydia trachomatis is the pathogen that is most often transmitted through sexual contact.
What classification is Chlamydia trachomatis?
ChlamydiaeChlamydia trachomatis / Class
What are the two forms of Chlamydia trachomatis?
Human diseases caused by chlamydiae can be divided into two types: (1) chlamydial agents transmitted by direct contact (C trachomatis genital and ocular infections, C pneumoniae ocular infection) and (2) chlamydial agents that are transmitted by the respiratory route (C psittaci and C pneumoniae.)
How do you read a chlamydia IgG test?
Negative Negative No evidence of infection. Positive Negative May indicate past infection. Positive Positive May indicate acute or chronic infection. Negative Positive May indicate acute or reactivation.
What is the standard range for chlamydia?
A positive culture confirms a C trachomatis infection with sensitivity between 50-85%. Nucleic acid amplification test (NAAT) has surpassed this as the criterion standard, with sensitivity ranging from 85-95% with 99-100% specificity.
What is the normal range of chlamydia?
Chlamydophila pneumoniae antibody is detectable in 25% to 45% of adults tested. IgG endpoint titers of 1:64 or more are considered presumptive evidence of current infection. IgG endpoint titers below 1:64 suggest that the patient does not have a current infection.
What is the difference between chlamydia and Chlamydia trachomatis?
Chlamydia is a common sexually transmitted disease. It is caused by bacteria called Chlamydia trachomatis. It can infect both men and women. Women can get chlamydia in the cervix, rectum, or throat.

- Negative or normal, which means the disease or substance being tested was not found.
- Positive or abnormal, which means the disease or substance was found.
What is Chlamydia trachomatis IgG positive and IgA negative?

How do I read my STD results?
Your STD test results may indicate “reactive,” “not-detected,” “non-reactive” or a reference range. Not detected and non-reactive mean the STD was not detected in your system. The reference range indicates whether the STD value is high enough to be considered positive; if not, it returns negative.
Where does Chlamydia trachomatis come from?
Chlamydia trachomatis is transmitted by oral, vaginal or anal sex, and can also be transmitted from mother to newborn during a vaginal delivery. Diagnosis is generally based on nucleic acid amplification tests (NAATs) carried out on cervical or vaginal swabs in women, urethral swabs in men or on urine samples.
How serious is Chlamydia trachomatis?
Is chlamydia serious? 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.
What is the reference range on a lab test result?
A reference range is a set of values that includes upper and lower limits of a lab test based on a group of otherwise healthy people. The values in between those limits may depend on such factors as age, sex, and specimen type (blood, urine, spinal fluid, etc.)
How is Chlamydia diagnosed and treated?
Screening and diagnosis of chlamydia is relatively simple. Tests include: A urine test. A sample of your urine is analyzed in the laboratory for presence of this infection. A swab. For women, your doctor takes a swab of the discharge from your cervix for culture or antigen testing for chlamydia.
What tests are used to screen for Chlamydia trachomatis?
BOX 1.Tests used for screening women for genitourinary tract infection Chlamydia trachomatis • A nucleic acid amplification test (NAAT) performed on an endocervical swab specimen, if a pelvic examina tion is acceptable; otherwise, a NAAT performed on urine.
What is a Naat test for chlamydia?
The most commonly used type of chlamydia test is called a Nucleic Acid Amplification Test (NAAT). A NAAT detects the DNA of the bacteria that cause the chlamydia infection. You provide a sample of urine.
