Microbiology
Colorado Tick Fever (Serological – Forwarded by TDSHS to CDC for testing.)
< Return to Table of Contents
Test Includes:

Reporting

Results Available: Contact #s:

Reference

Turnaround Time:  3 weeks Reference Range:  <1.00 (Nonreacative)  
Limitations: May not detect a recent infection, or infection in a person with a severely compromised immune system. Interpretation: Nonreactive indicates that the patient does not have detectable antibody to the infectious agent. Reactive indicates that the patient has detectable antibody to the infectious agent, and depending on the clinical picture, may have a current or past infection.

Specimen Requirements

Specimen Collection: Venipuncture Sample Type:
Volume/Amount Required: 10 mL whole blood Preferred Specimen:  Paired Sera
Collection/Preservation: Red top or tiger top tube Storage Instructions: Do not freeze or refrigerate whole blood. Separated serum may be held at 2-8°C
Causes for Rejection: Discrepancy between name on tube and name on form, insufficient quantity of serum for testing Sample Container: Red top or tiger top tube
Sample Test Kit: Availability:
Diagnostic Information:  Prior notification is requested (512) 458-7760. A detailed patient history is required. Serum specimens are forwarded to the CDC.  Serum specimens are to be collected at least 14 days apart.  A significant titer increase is evidence of current or recent infection.  Since IgM antibodies appear 14-16 days after onset, PCR test, with prior arrangement with CDC, can be performed on blood specimens collected within 8 days after onset.

Specimen Submission

Required Request Form: G-2A Specimen Handling: Use Universal Precautions
Transport Temperature:  Ambient temperature for specimens on the blood clot, separated serum at 2-8° C (refrigerated) or -20° C (frozen). Shipping Requirements: Triple contain, separated serum may be shipped on cold packs (2-8° C), or frozen (-20° C) and mailed on dry ice.
