Submit only 1 of the following specimens:
Swab specimen must be collected using an Aptima Collection Unisex Swab or Aptima Collection Multitest Swab. These swabs are contained in the Aptima Collection Kit.

3. Transfer 2 mL of urine into the Aptima Urine Specimen Transport Tube using the disposable pipette provided within 24 hours of collection. The correct volume of urine has been added when the fluid level is between the black fill lines on the urine transport tube. Place the labels on the transport tube so the black fill lines are still visible for volume confirmation at Mayo Clinic Laboratories.
4. Transport and store urine or post-prostatic massage urine (VBIII) specimen transport container at 2 to 30 degrees C (refrigerate is preferred temperature) within 30 days of collection. If longer storage is needed for urine specimens other than VBIII, freeze at -20 to -70 degrees C an additional 90 days.

Specimen Type: Peritoneal fluid (pelvic wash or cul-de-sac fluid)
Container/Tube: Aptima Specimen Transfer Tube
Specimen Volume: 1 mL
Collection Instructions:
1. After collection, peritoneal fluid can be stored at 2 to 30 degrees C for up to 24 hours.
2. Transfer specimen into the Aptima Specimen Transfer Tube within 24 hours of collection.
3. Cap tube securely and label tube with patient's entire name and collection date and time.
4. Transport and store specimen container at 2 to 30 degrees C (refrigerate is preferred temperature) within 30 days of collection.

Clinical Information

Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test
Mycoplasma genitalium, an under-recognized sexually transmitted infection (STI), causes acute and chronic non-gonococcal urethritis, cervicitis, and pelvic inflammatory disease. Due to its growing prevalence, M genitalium was cited as an emerging public health threat by the CDC in 2015. In high-risk populations, prevalence has been reported as high as 9% to 24% in male patients and 11% to 16% in female patients. M genitalium is commonly misdiagnosed as other STIs (eg, chlamydia and gonorrhea), which can lead to improper treatment of the underlying cause and an increase in duration of infection. In 2021, the CDC updated their STI guidelines to recommend that men with recurrent non-gonococcal urethritis and women with recurrent cervicitis and/or pelvic inflammatory disease should be tested for M genitalium.

Interpretation

Provides information to assist in interpretation of the test results
A positive result indicates the presence of nucleic acid from Mycoplasma genitalium.
A negative result indicates that nucleic acid from M genitalium was not detected in the specimen.
The predictive value of an assay depends on the prevalence of the disease in any particular population. In settings with a high prevalence of sexually transmitted infections, positive assay results have a high likelihood of being truly positive. In settings with a low prevalence of sexually transmitted infections, or in any setting in which a patient's clinical signs and symptoms or risk factors are inconsistent with urogenital infection, positive results should be carefully assessed, and if appropriate, the patient retested by other methods.
Cautions
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances

Care must be taken to avoid cross-contamination during handling of specimens.
This test does not detect other Mycoplasma or Ureaplasma spp.
This test is intended for use in clinical monitoring or management of patients; it is not intended for use in medico-legal applications.
Appropriate specimen collection and handling is necessary for optimal assay performance.
Results should be interpreted in conjunction with other laboratory and clinical findings.
A negative test result does not exclude the possibility of infection. Improper specimen collection, concurrent antibiotic therapy, presence of inhibitors, or low numbers of organisms in the specimen (ie, below the sensitivity of the test) may cause false-negative test results.
In low prevalence populations, positive results must be interpreted carefully as false-positive results may occur more frequently than true-positive results in this setting.
In general, this assay should not be used to assess therapeutic success or failure, since nucleic acids from these organisms may persist for 3 weeks or more following antimicrobial therapy.
The effects of use of tampons, douching, specimen types other than those listed in Specimen Required, and specimen collection variables have not been determined.
Testing of urine specimens with this method is not intended to replace cervical exam and endocervical sampling for diagnosis of urogenital infection; infections may result from other causes or concurrent infections may occur.
Interference in assay results was observed when mucus at a final concentration of 0.3% w/v was added to clinical specimen matrix. Interference was not observed when mucus at a final concentration of 0.03% w/v was added to clinical specimen matrix.
Performance of the assay has not been evaluated in individuals < 15 years of age

The HOLOGIC APTIMA Combo 2 Assay combines the technologies of target capture, transcription-mediated amplification, and dual kinetic assay. The detection of the ribosomal RNA amplification product sequences (amplicon) is achieved using nucleic acid hybridization. Single-stranded chemiluminescent DNA probes are labeled and combine with amplicon to form stable RNA:DNA hybrids. Light emitted from the labeled RNA:DNA hybrids is measured as photon signals in a luminometer.(Package insert: APTIMA Mycoplasma genitalium Assay. AW-1794 Hologic, Inc; Rev 002, 04/2019)
