Malaria Antibody, IgG : 0051356

Mnemonic: MALARIA AB

Methodology: Semi-Quantitative Enzyme-Linked Immunosorbent Assay
Performed: Tue
Reported: 1-8 days
Specimen Required: Collect: Serum separator tube.

Specimen Preparation: Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.05 mL)

Storage/Transport Temperature: Refrigerated.

Unacceptable Conditions: Contaminated, heat-inactivated, hemolyzed, icteric, lipemic, or turbid specimens.

Stability (collection to initiation of testing): After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year

Reference Interval:
Less than 1.01 IV
Interpretive Data: A positive result, with consistent clinical symptoms and history, suggests malarial infection by any of the following species: P. falciparum, P. vivax, P. malariae, or P. ovale. Malaria Smear (Giemsa Stain), test number 0049025, of a blood smear should be performed for confirmation. Giemsa stain may not detect parasites in low numbers or in past infection. IFA has limited utility in the speciation of past malaria infections because of extensive cross-reactivity between species.
