Dengue Fever Virus Antibody, IgM : 0093098

Mnemonic: DEN M

Methodology: Enzyme-Linked Immunosorbent Assay
Performed: Mon
Reported: 1-8 days
Specimen Required: Collect:  One 4 mL serum separator tube.

Transport:  1 mL serum at 2-8°C. (Min: 0.2 mL)  Submit specimen in an ARUP Standard Transport Tube.

 


Pediatric Collection/Transport:  0.1 mL serum at 2-8°C.

Remarks:  Separate serum from cells ASAP.  Acute and convalescent specimens must be labeled as such; parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens.  Please mark specimen plainly as "acute or convalescent."

Unacceptable Conditions:  Severely lipemic, contaminated, heat-inactivated, or hemolyzed specimens.

Stability:  After separation from cells: Ambient: 2 days; 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. 

Please refer to Statement D in the Compliance Statements section in the front of the Laboratory Test Directory.
