• 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.

HME (Ehrlichia chaffeensis) PCR Whole Blood
$230.00
The polymerase chain reaction (PCR)-based diagnostic assays are highly specific to Ehrlichia chaffeensis (HME) DNAs. The combination of the following three steps imparts a very high specificity and sensitivity to the test:
1. Hybridization/selection
2. Amplification of Ehrlichia-specific DNA
3. Detection of Ehrlichia-specific amplified DNA fragments
Principle
The Ehrlichia chaffeensis (HME) PCR test detects E. chaffeensis ribosomal DNA (rDNA) fragments in patient samples. The rDNA fragments are hybrid-selected by probes, followed by PCR amplification of the selected fragments using specific primers. PCR products are then confirmed with E. chaffeensis-specific probes by southern blot assay.

Positive: E. chaffeensis rDNA detected.
Negative: E. chaffeensis rDNA not detected.
- Ehrlichia test results should be interpreted in conjunction with other laboratory and clinical findings.
- Test results can only help the physician in confirming a clinical diagnosis.
