HelpTest Code MHRP Metamycoplasma hominis, Molecular Detection, PCR, Varies
Reporting Name
Mycoplasma hominis PCRUseful For
Rapid, sensitive, and specific identification of Metamycoplasma hominis from synovial fluid, genitourinary, reproductive, lower respiratory sources, pleural/chest fluid, pericardial fluid, and wound specimens
This test is not intended for medicolegal use.
Performing Laboratory
Mayo Clinic Laboratories in Rochester
Specimen Type
VariesNecessary Information
Specimen source is required.
Specimen Required
The high sensitivity of amplification by polymerase chain reaction (PCR) requires the specimen to be processed in an environment in which contamination of the specimen by Mycoplasma hominis DNA is not likely.
Submit only 1 of the following specimens:
Specimen Type: Swab
Supplies:
-Culturette (BBL Culture Swab) (T092)
-BD E-Swab (T853)
-M4-RT (T605)
Sources: Vaginal, cervix, urethra, urogenital, chest/mediastinal; bronchus or lung (donor swab); or upper respiratory sources (only infants <3 months: nasopharynx, nose, throat)
Container/Tube:
Preferred: Culture swab transport system (Dacron or rayon swab with aluminum or plastic shaft with either Stuart or Amies liquid medium)
Acceptable: Swab in transport media: M4, M4-RT, M5, M6, universal transport media, or ESwab
Specimen Volume: 1 swab
Collection Instructions:
Vaginal:
1. Collect specimen by swabbing back and forth over mucosa surface to maximize recovery of cells.
2. Place swab back into swab cylinder.
Urethra or cervical:
1. Collect specimen by inserting swab 1 to 3 cm and rotating 360 degrees.
2. Place swab back into swab cylinder.
Wound:
1. Collect specimen by swabbing back and forth over wound surface to maximize recovery of cells.
2. Place swab back into swab cylinder.
Specimen Type: Fluid
Sources: Pelvic, peritoneal, amniotic, prostatic secretions, semen, reproductive drainage or fluid, pleural/chest, chest tube, pericardial
Container/Tube: Sterile container
Specimen Volume: 1 to 2 mL
Specimen Type: Respiratory
Sources: sputum, tracheal secretions, bronchial washings, bronchoalveolar lavage, lung; or nasal washings (Note: Nasal washings may only be submitted for infants <3 months of age.)
Container/Tube: Sterile container
Specimen Volume: 1 to 2 mL
Specimen Type: Synovial fluid
Container/Tube:
Preferred: Lavender top (EDTA)
Acceptable: Pink top (EDTA), royal blue top (EDTA), sterile vial containing EDTA-derived aliquot, red clot tube (no anticoagulant), or sterile container
Specimen Volume: 0.5 mL
Collection Instructions: Send specimen in original tube.
Specimen Type: Urine (first void), kidney/bladder stone, or ureter
Container/Tube: Sterile container
Specimen Volume: 10 mL or entire specimen
Collection instructions: Urine first void: Specimen can be collected at any time during the day. The patient should not have urinated for at least 1 hour prior to specimen collection. The first voided portion is the initial 20 to 30 mL of the urine stream obtained without cleaning the external urethra.
Specimen Type: Tissue
Sources: Placenta, products of conception, urogenital, respiratory, bronchus, chest/mediastinal, bone, spine, or joint
Container/Tube: Sterile container
Specimen Volume: 5 mm(3)
Collection Instructions:
1. Collect fresh tissue specimen.
2. Submit fresh tissue only, do not add fluid to tissue
3. Refrigerate or freeze specimen.
Specimen Minimum Volume
Fluid: 1 mL
Urine, first void: 2 mL
Swab: 1 swab
Tissue: 5 mm(3)
