Strongyloides IgG Antibody, ELISA

CERNER / EPIC MNEMONIC:

STRONG AB

POE DESCRIPTION:

STRONGYLOIDES IGG AB

CPT CODE:

86682

TEST INFORMATION:

Strongyloides stercoralis is a parasitic nematode found in tropical and subtropical regions. Because of low larval densities in feces, stool examination is a relatively insensitive diagnostic test; serodiagnosis by ELISA offers increased sensitivity. Antibody titers decrease in many patients following treatment. Patients with latent infections who are immunosuppressed or receiving immunosuppressive therapy are at risk life-threatening hyperinfection. The assay shows 90% sensitivity and 90% specificity.
