Specimen Required
Patient Preparation
 
Collect
Serum separator tube.  
Specimen Preparation
Separate serum from cells ASAP or within 2 hours of collection. Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.1 mL) Parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens. Mark specimen plainly as "acute or convalescent."  
Storage/Transport Temperature
Refrigerated.  
Unacceptable Conditions
Contaminated, heat-inactivated, hemolyzed, or severely lipemic specimens.  
Remarks
 
Stability
After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)  
Reference Interval
1.64 IV or less: Negative - No significant level of detectable dengue fever virus IgM antibody.
1.65-2.84 IV: Equivocal - Questionable presence of antibodies. Repeat testing in 10-14 days may be helpful.
2.85 IV or greater: Positive - IgM antibody to dengue fever virus detected, which may indicate a current or recent infection.
However, low levels of IgM antibodies may occasionally persist for more than 12 months post-infection.
Interpretive Data
The best evidence for current infection is a significant change on two appropriately timed specimens, where both tests are done in the same laboratory at the same time.
