Microbiology
Mumps (Culture - Isolation)
< Return to Table of Contents
Test Includes: Cell culture

Reporting

Results Available: 2-14 days Contact #s: 512-458-7594

Reference

Method: Cell Culture  
Turnaround Time:  2-14 days Reference Range:  No virus isolated
Limitations: Interpretation: A result of “No virus isolated” does not necessarily mean absence of a viral agent.  The success of virus isolation depends a great deal on the submission of the proper specimen, collected at the right time, adequately maintained, and shipped with the least possible delay.

Specimen Requirements

Specimen Collection: Specimens should be collected at an appropriate anatomic site and at the proper time after infection because viruses are generally shed for only a short period of time.  Refer to Specimen Collection by Type table for additional instructions.  Sample Type: See preferred specimen.
Volume/Amount Required: 2-5 mL of CSF, 10-20 mL of urine, or saliva collected with swab in 2-3 mL of viral transport media. Preferred Specimen:  CSF; Urine; Saliva
Collection/Preservation: Viral transport media. Storage Instructions: Arriving < 48 hours after collection, store and send at 2-8° C. Arriving > 48 hours after collection, store and send at -70° C (dry ice).
Causes for Rejection: Specimens submitted on preservative such as formalin. Sample Container: Sterile container
Sample Test Kit: Availability: Monday - Friday
Diagnostic Information:  Specimens are inoculated onto a variety of cell cultures.  If characteristic CPE or hemadsorption is observed, confirmation of identification will be performed.

Specimen Submission

Required Request Form: G-2A Specimen Handling:
Transport Temperature:  
Arriving <48 hours:  2-8 °C (refrigerated)
Arriving >48 hours:  ship on dry ice  
Shipping Requirements: Ship specimens in compliance with governmental regulations.

< Return to Table of Contents
Test Includes:

Reporting

Results Available: Contact #s:

Reference

Method: EIA  
Turnaround Time:  5-7 days Reference Range:  Nonreactive
Limitations: May not detect a recent immunization or infection, or immune status 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: 2 mL Serum Preferred Specimen:  Single Serum; Paired Sera
Collection/Preservation: Samples that will be delivered to the laboratory within 8 hours of collection may be transported at room temperature in the original blood collection tube. If the samples are going to be shipped and will be delivered to the laboratory within 48 hours of collection, sera must be separated from the blood and shipped on cold packs, between 2° and 8°C. If the serum samples will not be delivered to the laboratory within 48 hours of collection at these temperatures, then the samples must be frozen at -20°C or lower and shipped on dry ice. Storage Instructions: Separated serum may be held at 2-8°C, or frozen at -20°C.
Causes for Rejection: Discrepancy between name on tube and name on form, insufficient quantity of serum for testing, specimens received with extended transit time, or received at incorrect temperature. Sample Container: Red top or tiger top tube
Sample Test Kit: Availability: Test is performed once per week
Diagnostic Information:  Acute and convalescent serum specimens are to be collected 14 days apart.  A significant EIA antibody rise is evidence of current or previous infection. Test is performed once per week.

Specimen Submission

Required Request Form: G-2A Specimen Handling: Use Universal Precautions
Transport Temperature: Cold (2-8º C) on ice packs if received within 48 hours from time of collection. Frozen (≤-20°) on dry ice if received more than 48 hours from time of collection. Shipping Requirements: Triple contain, separated serum may be shipped on cold packs (2-8°C), or frozen (-20°C) and mailed on dry ice.

Positive reports are telephoned to the submitter.
Reference Range:   By Report
Limitations: Specimens that have been in transit for more than 6 days from the date of collection are not acceptable. Test can only be run on undiagnosed, untreated patients on processed non-bloody pulmonary specimens.  A negative test does not mean the patient does not have M. tuberculosis disease.  All tests must be confirmed by culture of specimen for the presence of mycobacteria. Interpretation: A Positive MTD test means that the probe detected ribosomal RNA of the M. tuberculosis complex in the clinical specimen.

Specimen Requirements

Specimen Collection: Sample Type: Clinical pulmonary specimen
Volume/Amount Required: 3 mL to 15 mL Preferred Specimen:  Sputum; Bronchial Washings Specimen can not be bloody

Mycobacteriosis (Microscopic – Truant’s Stain)

Test Includes: Microscopic Examination of Clinical Specimen for Acid Fast Bacilli (AFB)

Reporting

Results Available: 1 day. Positive reports are telephoned to the submitter within two hours of availability. Contact #s: 512-458-7586

Reference

Method: Truant’s Acid Fast Stain  
Turnaround Time:  24 hours Reference Range:  Negative
Limitations:  A negative microscopic examination does not mean that the patient’s specimen cannot be culture positive for AFB.  This test is less sensitive than culture.  The stain utilizes a fluorescent dye that can be taken up by the mycobacterium to different degrees depending on the species or if the patient is on antibiotic treatment.  The quality of the specimen has major impact on the results of the microscopic examination. Interpretation:  The report states whether the test is Negative if No AFB are Seen or Positive if AFB are Seen on microscopic examination.  If Positive, the report provides a quantitation to indicate how many AFB were seen in a high power field under the microscope.  Occasionally, an examination will result in the observation of only one or two AFB in the entire test.  This number of AFB (one or two) is reported but is not considered a positive result by CDC or the American Thoracic Society.

Specimen Requirements

Specimen Collection: Sample Type:
Volume/Amount Required: 3 mL to 15 mL
Preferred Specimen:  Sputum; Tissue; Exudate; Stool; Blood; Body Fluids; Urine
Collection/Preservation: No preservative Storage Instructions: Transport specimen as soon as possible.  If transport is delayed over one hour, refrigerate specimen, unless blood.  This is important if the specimen is also to be cultured.
Causes for Rejection: Specimens received frozen, in formalin, or in culture medium will be rejected.  Swabs are discouraged unless the only specimen available; submit swabs in 5 mL sterile saline.  If swabs are submitted in transport medium, the test cannot be performed. Sample Container: Triple contained. Sterile, leak-proof, 50 mL conical tube preferred for primary container.
