Human T-Lymphotropic Virus I/II Antibody (HTLV I/II)

CERNER / EPIC MNEMONIC:

HTLV I/II

CPT CODE:

86790, if positive confirmatory test = 86689

TEST INFORMATION:

The test includes detection of antibody to HTLV I/II.

DAYS PERFORMED:

Monday - Sunday

TURNAROUND TIME:

2 - 5 days

CONTAINER TYPE:

Red top vacutainer  tube or SST tube

SPECIMEN REQUIREMENTS:

Blood

REJECTION CRITERIA:

Excessive hemolysis, gross contamination of specimen, chylous serum, improper storage of specimen, inappropriate specimen container, insufficient specimen volume.

MINIMUM VOLUME:

5 mL blood (1 mL serum)

HANDLING INSTRUCTIONS:

Specimen should be transported as soon as possible. When transportation is delayed,  refrigerate. Ship refrigerated.

REFERENCE RANGE:

Nonreactive   See Quest Test Code 36175

LIMITATIONS OF TEST:

A negative result does not preclude the possibility of infection with HTLV-I/II.

METHODOLOGY:

Chemiluminescence,  Immunoassay

REFERRAL LABORATORY:

Quest Diagnostics

ADDITIONAL INFORMATION:

HTLV-I causes adult T cell leukemia (ATL) or HTLV-associated myelopathy (HAM) in approximately 10% of infected individuals. HTLV-II is closely related to HTLV-I, but disease associations are less clear. Positive or equivocal HTLV-I/II screening test results will be tested further by HTLV CONFIRMATORY ASSAY at an additional charge which usually differentiates HTLV-I from HTLV-II infection.
