HTLV Blood Screening & Confirmation

HTLV screening of blood donor samples for transfusion-transmissible infections is recommended by the World Health Organization (WHO) for the provision of safe blood products, and is supported by the Centers for Disease Control and Prevention (CDC) and the Global Virus Network (GVN) HTLV Task Force. Our highly sensitive HTLV I/II ELISA 4.0 enables your lab to screen blood donors with great confidence. Trust our assays to ensure confidence in the safety of your blood supply and reduce HTLV transmission through blood transfusion.

Reliable HTLV Confirmation and Donor Typing

The HTLV Blot 2.4 is intended for the in vitro detection of antibodies to HTLV-I and HTLV-II in human serum or plasma, as a more specific supplemental test on donor specimens found repeatedly reactive using screening procedures. It delivers outstanding performance with a combination of HTLV-I viral proteins and patented recombinant proteins from HTLV-I and HTLV-II. Together, the HTLV I/II ELISA 4.0 and HTLV Blot 2.4 help to support the global efforts to eradicate HTLV.

The MPD HTLV-I/II ELISA 4.0 is a direct sandwich immunoassay that utilizes a combination of recombinant proteins and a tri-fusion recombinant protein labeled with horseradish peroxidase. The MPD HTLV-I/II ELISA 4.0 is intended as a semi-qualitative enzyme-linked immunosorbent assay for the detection of antibodies to both HTLV-I and HTLV-II found in human serum or plasma.


The MP Diagnostics HTLV I/II ELISA 4.0 is an enzyme-linked immunosorbent assay intended for the detection of antibodies to Human T-cell Lymphotropic Virus type 1 (HTLV-I) and type 2 (HTLV-II) in human serum or plasma. It is intended as a screening test, requiring repeat testing of initially reactive specimens.
