Chlamydia Trachomatis IgM ELISA Kit


Human Chlamydia trachomatis IgM ELISA kit is a method intended for in-vitro quantitative detection of human IgM class antibodies to Chlamydia trachomatis (Chlamydia trachomatis-IgM) present in samples of plasma and serum. This assay has a minimum analytical sensitivity limit to a diagn. 83.3%.


Chlamydia trachomatis infections are one of the most frequent reported sexually transmitted infection (STI), especially within the United States. However, the majority of these chlamydial infections are asymptomatic, which can provide an ongoing reservoir for future infections. There are a large number of publications which have reported that untreated chlamydial infection can cause serious sequelae, such as pelvic inflammatory disease (PID), chronic pelvic pain and tubal infertility. The most common clinical manifestation of chlamydial infection found in men is urethritis, whereas in women it is cervicitis. Chlamydial infection during pregnancy have been linked to an increased risk of preterm labour, perinatal mortality and low birth weight. Until recently, one of the major hindrance in controlling chlamydial infections has been the lack any available specific, sensitive and inexpensive diagnostic test. Screening programs have also been undertaken in order to reduce the overall prevalence of chlamydial infection present within the tested population.


All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.

Your secretory IgA ELISA gave good results and I was also really impressed with how quickly we received it.

It is refreshing to know that you have a technical team that is very knowledgeable. I have already recommended your company to other researchers in our department.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA assay performed well and I was happy with the results that were generated.

I carried out a pilot study comparing the performance of many ELISA assay's from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.

You are my first point of contact when I am looking to purchase ELISA. You have such an easy and simple system, yet it is very effective.
