Synonyms
- Mycoplasma hominis Genital Culture
- Mycoplasma T-Strain Culture, Genital
- Ureaplasma Culture
- Culture, Mycoplasma hominis (Genital Specimens)
- Culture, Ureaplasma urealyticum, Genital
Test Includes
Culture; isolation and identification if culture results warrant (additional charges/CPT code[s] may apply). CPT coding for microbiology and virology procedures often cannot be determined before the culture is performed.
Special Instructions
Submit one specimen per test requested. Specify the exact specimen source/origin (e.g., genital lesion). Indicate a specific test number on the request form.
Expected Turnaround Time
6 - 10 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.

Specimen Requirements
Specimen
Endocervical exudates or scrapings, urethral exudate, urine, endometrial washing or biopsy, fallopian tube, placenta, fetal part, semen; cerebrospinal fluid (CSF), respiratory sources from neonates
Volume
Entire container
Container
Viral, Chlamydia or Mycoplasma culture transport provided by Labcorp, or other appropriate transport medium
Collection
• Females and Males: Collect a vaginal or urethral specimen using an appropriately sized synthetic swab. Place swab in viral transport media (VTM). Refrigerate and ship to the laboratory at 2-8°C.
• Semen/Urine/Biopsy/Tissue/CSF: Collect specimen in a sterile, leakproof container. Refrigerate and ship to the laboratory at 2-8°C.
Storage Instructions
Refrigerate and ship to the laboratory at 2-8°C.
Causes for Rejection
Bacterial swab specimen; specimen received in grossly leaking transport container; dry specimen; specimen submitted in fixative or additive; specimen received in expired transport media or incorrect transport device; specimen received in M4 RT VTM; inappropriate specimen transport conditions; specimen received after prolonged delay in transport (usually more than 72 hours); specimen stored or transported at room temperature; wooden shaft swab in transport device; calcium alginate swabs; unlabeled specimen or name discrepancy between specimen and request label
Test Details
Use
Establish the diagnosis of Ureaplasma urealyticum infection in suspected cases of urethritis and cervicitis
Limitations
Culture may be negative in the presence of infection, and the presence of Ureaplasma urealyticum or Mycoplasma hominis does not always indicate infection, although there is a significant association with symptomatic disease.
Methodology
Culture on selective media1
Reference Interval
Negative
Additional Information
Ureaplasma and Mycoplasma can be isolated from urethral and genital swabs and from urine of sexually active individuals. Sixty percent or more of all women asymptomatically carry U urealyticum in their genital tract. Usual prevalence of these organisms in patients with urethral symptoms also is high; thus, conclusions regarding the etiologic role of an isolate in a given patient are difficult to make. Nevertheless, Ureaplasma urealyticum has been associated with cases of nongonococcal urethritis.
