Special Info
Heat inactivation of samples is not recommended. Avoid repeat freezing and thawing of the specimen. Bacterial contamination may affect results and should be avoided. Patients with equivocal results should have the test repeated with a fresh sample in 2-4 weeks.
Clinical Info
This test detects IgG produced against two recombinant and specific Strongyloides stercoralis antigens. It cannot determine the time of infection, however, it can be negative during the first few weeks after an acute infection. IgG levels may remain elevated for life but may also decline with adequate treatment. Equivocal results may be seen during early infection, years after spontaneous clearance, post treatment, in immunosuppressed patients, or due to cross-reactivity with certain nematodes, Filariae among others. Clinical and epidemiological correlation is required.
Clinical Limitation
Cross reactions with antibodies against other worms and parasites cannot be excluded.
