Mnemonic: DENGUE AB

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

Storage/Transport Temperature: 1 mL serum at 2-8°C. (Min: 0.1 mL) Submit specimen in an ARUP Standard Transport Tube.

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 (collection to initiation of testing): After separation from cells: Ambient: 2 days; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
Reference Interval:
Test Number Components Reference Interval
0093097Dengue Fever Virus Antibody, IgG 1.64 IV or less: Negative - No significant level of detectable dengue fever virus IgG 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 - IgG antibody to dengue fever virus detected, which may indicate a current or past infection.
0093098Dengue Fever Virus Antibody, IgM 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.
