HelpTest Code URPRP Ureaplasma species, Molecular Detection, PCR, Plasma
Reporting Name
Ureaplasma PCR, PPerforming Laboratory
Mayo Clinic Laboratories in Rochester
Useful For
Rapid, sensitive, and specific identification of Ureaplasma urealyticum and Ureaplasma parvum from plasma
This test is not intended for medicolegal use.
Method Name
Real-Time Polymerase Chain Reaction (PCR) using LightCycler and Fluorescent Resonance Energy Transfer (FRET)
Specimen Required
The high sensitivity of amplification by polymerase chain reaction requires the specimen to be processed in an environment in which contamination of the specimen by Ureaplasma DNA is unlikely.
Collection Container/Tube:
Preferred: Lavender top (EDTA)
Acceptable: Royal blue top (EDTA), pink top (EDTA), or sterile vial containing EDTA-derived aliquot
Submission Container/Tube: Screw-capped, sterile container
Specimen Volume: 1 mL
Collection Instructions: Centrifuge and aliquot plasma into a plastic vial.
Specimen Type

Interpretation
A positive polymerase chain reaction (PCR) result for the presence of a specific sequence found within the Ureaplasma urealyticum and Ureaplasma parvum ureC gene indicates the presence of U urealyticum or U parvum DNA in the specimen.
A negative PCR result indicates the absence of detectable U urealyticum and U parvum DNA in the specimen but does not rule out infection as false-negative results may occur due to inhibition of PCR, sequence variability underlying the primers and probes, or the presence of U urealyticum or U parvum in quantities below the limit of detection of the assay.
