Clinical Significance

HTLV-I/II Antibody, with Reflex to Confirmatory Assay - This test is intended to aid in the clinical diagnosis of Human T-lymphotropic Virus Type I (HTLV-1) or Type II (HTLV-II) infection. An ELISA is used for the initial detection of antibodies to HTLV-I/II. Specimens with reactive ELISA results reflex to supplemental testing using a line immunoassay (LIA) for confirmation and
differentiation of HTLV type.
While the ELISA assay is highly sensitive, specimens containing low titers of antibodies from certain areas of endemicity, or specimens from early sero-converters may be missed. Repeat testing should be considered where there is clinical suspicion ...

Collection Instructions

Label the tubes according to your standard operating procedure, making sure that each tube has at least two unique patient identifiers.

If transport temperature will be frozen, centrifuge the red/lavender-top and transfer the serum/plasma into a plastic, screw-cap vial. The plastic, screw-cap vial (aliquot tube) containing serum or plasma must be labeled with the specimen type (serum or plasma) and at least two unique identifiers. Aliquot tubes must be processed and labeled at the original collection site. If aliquot tubes are submitted, do not send the original red/lavender-top. Room temperature transport is acceptable. Do not store at room temperature.
