Human T-Lymphotropic Virus (HTLV) I/II Qualitative Real-time PCR
Human T-Lymphotropic Virus (HTLV) I/II Qualitative Real-Time PCR assay detects and distinguishes HTLV-1 virus, which can cause adult T-cell leukemia/lymphoma and other serious conditions, and HTLV-2 virus. HTLV-2 virus currently is not definitively known to cause specific disease. HTLV proviral DNA is integrated into the genomes of human T-lymphocytes; therefore all U.S. donors of blood, blood derived products, hematopoietic stem cells, living organ donors and, in some cases, organs rich in leukocytes should be screened by serological testing. This PCR assay is not cleared or approved for in vitro diagnostic use and should be used in conjunction with clinical evaluation to aid in diagnosis.
Extraction of viral DNA from whole blood followed by amplification and detection using real-time, qualitative PCR. The real-time PCR assay is designed to detect and distinguish HTLV-1 and/or HTLV-2 proviral DNA (that is, viral DNA copies integrated into the genomes of human T-lymphocytes). An internal control is added to ensure the extraction was performed correctly and the PCR reaction was not inhibited. This test has not been cleared or approved for diagnostic use by the U.S. Food and Drug Administration.
Detects 5 HTLV-1 subtypes (1a, 1b, 1c, 1f and 1g) and 3 HTLV-2 subtypes (2a, 2b and 2d) in one assay. The primers and probes used in this assay are specific and inclusive for all 8 subtypes listed. Additionally, potential cross-reactivity was evaluated with various pathogens that could cause similar symptoms or pathogens related to HTLV due to sequence identity.
