• Enables accurate identification of biochemically unusual strains of pathogen.
• Facilitates much earlier detection of the microorganism because the assay is independent of the host’s immune response schedule.
Therefore, PCRs are useful for seronegative patients as well.
• Allows monitoring of the efficacy of an antibiotic regime.
• PCRs detect the DNA of the bacteria itself. Therefore, a positive result is definitive.
Test
Rickettsia PCR Urine
$230.00
The polymerase chain reaction (PCR)-based diagnostic assay for detection of Rickettsia from urine is highly specific to R. rickettsii and R. felis/typhi DNAs. The combination of the following three steps imparts a very high specificity and sensitivity to the test:
- Hybridization/selection
- Amplification of Rickettsia-specific DNA
- Detection of Rickettsia-specific amplified DNA fragments
Principle
The Rickettsia species PCR test is an assay that detects Rickettsia species-specific DNA in clinical samples. Rickettsia 17 kDa antigen gene fragments are hybrid-selected by probes, followed by PCR amplification of the selected DNA fragment. PCR products are tested with Rickettsia-specific probes (R. rickettsii and R. felis/typhi) by southern blot assays. The primers and probes used for the selection of a Rickettsia gene fragment encoding the 17 kDa antigen DNA fragments are designed from published sequences.

Sample Report
View
Positive: Rickettsia specific DNA detected.
Negative: Rickettsia specific DNA not detected
- This test should only be performed in conjunction with southern blot assays.
- Results should be interpreted in conjunction with other laboratory and clinical findings.
- Test results can only help the physician in confirming a clinical diagnosis.
