Respiratory Viruses DFA with Reflex to Respiratory Virus Mini Panel by RT-PCR : 2002565

Mnemonic: RSPFAPCR

Methodology: Direct Fluorescent Antibody Stain
Performed: Sun-Sat
Reported: Within 24 hours
Specimen Required: Collect: Nasal aspirate, nasopharyngeal swab. Transport in viral transport media (ARUP Supply #12884). Source of specimen is required.

Storage/Transport Temperature: Specimen in viral transport media at 2-8°C. (Min: 2 mL) Source of specimen is required. Place each specimen in a separate, individually sealed bag.

Submit specimen according to Biological Substance, Category B, shipping guidelines.


Remarks: Do not freeze. Do not send slides.

Unacceptable Conditions: Dry swabs, leaking or nonsterile containers

Stability (collection to initiation of testing): Ambient: 2 hours; Refrigerated: 3 days; Frozen: Unacceptable
Reference Interval:
Negative
Interpretive Data: If DFA is negative or inadequate for influenza, then a Respiratory Virus Mini Panel by RT-PCR (test code 0060764) will be added.

Sensitivity of DFA methodology is dependent upon adequacy of the specimen.  If there are fewer than 20 cells, the DFA result will be reported as "specimen inadequate."
