The summary describes a nucleic acid probe test for detecting Chlamydia trachomatis. There is no mention of AI, ML, image processing, or any other technology typically associated with AI/ML in medical devices. The description focuses on the biological and chemical aspects of the assay.
No
This device is for in vitro diagnostic (IVD) use to aid in the diagnosis of chlamydial urogenital disease, not for treatment.
Yes
The "Intended Use / Indications for Use" section explicitly states that the assay is used "to aid in the diagnosis of chlamydial urogenital disease."
No
The device description clearly indicates it is a "target amplification nucleic acid probe test," which involves physical reagents and laboratory procedures, not solely software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The "Intended Use / Indications for Use" section explicitly states that the assay is for the "in vitro qualitative detection of ribosomal RNA (rRNA) from Chlamydia trachomatis". "In vitro" means "in glass" or "outside the body," which is a key characteristic of IVDs.
- Device Description: The "Device Description" also reiterates that it is an "in vitro qualitative detection" test.
- Purpose: The assay is used to test specimens from individuals "to aid in the diagnosis of chlamydial urogenital disease." This diagnostic purpose is a core function of IVDs.
- Specimen Types: The assay analyzes biological specimens (swabs and urine) collected from the patient, which is typical for IVDs used for diagnostic testing.

§ 866.3120 Chlamydia serological reagents.
(a)
Identification. Chlamydia serological reagents are devices that consist of antigens and antisera used in serological tests to identify antibodies to chlamydia in serum. Additionally, some of these reagents consist of chlamydia antisera conjugated with a fluorescent dye used to identify chlamydia directly from clinical specimens or cultured isolates derived from clinical specimens. The identification aids in the diagnosis of disease caused by bacteria belonging to the genusChlamydia and provides epidemiological information on these diseases. Chlamydia are the causative agents of psittacosis (a form of pneumonia), lymphogranuloma venereum (a venereal disease), and trachoma (a chronic disease of the eye and eyelid).(b)

Device Description
The APTIMA Assay for Chlamydia trachomatis is a target amplification nucleic acid probe test that utilizes target capture for the in vitro qualitative detection of rRNA from Chlamydia trachomatis in clinician-collected endocervical, vaginal and male urethral swab specimens, patient-collected vaginal swab specimens, and female and male urine specimens. The APTIMA Assay for Chlamydia trachomatis (APTIMA CT Assay) may be used to test specimens from symptomatic and asymptomatic individuals to aid in the diagnosis of chlamydial urogenital disease.
Background on the Disease and Principle of the Test
The Disease
Chlamydia trachomatis (CT) infections are one of the most common sexually transmitted infections worldwide. In the United States alone, an estimated 783,242 new cases of C. trachomatis infections were reported in 2001(CDC, 2003). J
Chlamvdiae are nonmotile, gram-negative, obligate intracellular bacteria. The C. trachomatis species is comprised of fifteen serovars that can cause disease in humans. The serovars D through K are the major cause of genital chlamydial infections in men and women (Schachter, Children born to infected mothers are at significantly higher risk for inclusion 1985). conjunctivitis and chlamydial pneumonia (Beem and Saxon, 1977; Frommell et al., 1979; Schachter and Grossman, 1981).
Screening for the presence of these diseases is the cornerstone for prevention strategies. A large number of these cases may be asymptomatic or have symptoms that are not specific; this makes reduction of the prevalence of chlamydial and gonococcal infections difficult. An accurate and prompt diagnosis of these infections is important to ensure appropriate patient

management, to prevent disease complications and their associated medical costs, and to control transmission to uninfected partners.
Historical and Conventional Methods
Historically, several methods for C. trachomatis detection have been utilized in the clinical laboratory, including cell culture, direct fluorescent antibody testing, and enzyme immunoassay. More recent methodologies for C. trachomatis detection include direct DNA probe assays and nucleic acid amplification tests (NAATs). Cell culture was once considered to be the "gold standard" for detection of C. trachomatis. Culture is quite specific, but recent publications have demonstrated that NAATs have a higher clinical sensitivity than culture (Buimer et al., 1996; Crothfelt et al., 1998; Jaschek et al., 1993; Stary et al., 1998). Due to its lower clinical sensitivity and variable performance between laboratories, culture has been replaced in many laboratories by direct DNA probe and NAATs.
First generation NAATs for C. trachomatis have technological issues that have limited their performance. These issues include cumbersome specimen and specimen inhibition that can yield false negative results (Chernesky et al., 1996; Goessens et al, 1997; Mahony et al., 1998; Peterson et al., 1997; Toye et al, 1998; Vincelette et al., 1999). The GEN-PROBE APTIMA Assay for Chlamydia trachomatis (APTIMA CT Assay) is a second generation NAAT that utilizes target capture, Transcription-Mediated Amplification (TMA), and Hybridization Protection Assay (HPA) technologies to streamline specimen processing, amplify target rRNA, and detect amplicon, respectively. Recent studies comparing performance and specimen inhibition of various amplification systems have demonstrated the benefits of target capture, TMA, and HPA (Chong et al., 2003; Gaydos et al, 2003).

2001 in the United States alone, (CDC, 2003). The C. trachomatis species is comprised of fifteen serovars that can cause disease in humans. The serovars D through K are the major cause of genital chlamydial infections in men and women (Schachter, 1985). C. trachomatis can cause nongonococcal urethritis, epididymitis, cervicitis, acute salpingitis, and Pelvic Inflammatory Disease (PID) (Cates and Wasserheit, 1991; Holmes et al., 1975; Schachter 1978; Schachter et al., 1975). C. trachomatis infections are often asymptomatic in both males and females. Children born to infected mothers are at significantly higher risk for inclusion conjunctivitis and chlamydial pneumonia (Beem and Saxon, 1977; Frommell et al., 1979; Schachter and Grossman, 1981).
Treatment of symptomatic patients is only partially effective because of the large percentage of asymptomatic patients.
