Geenius HIV-1/HIV-2 Supplemental Assay Press Release


Bio-Rad's Geenius™ HIV-1/HIV-2 Supplemental Assay detects and differentiates circulating antibodies to HIV Types 1 and 2

HERCULES, CA – November 24, 2014 – Bio-Rad Laboratories, Inc.'s (NYSE: BIO and BIOb) Geenius HIV-1/HIV-2 Supplemental Assay can differentiate circulating antibodies to Human Immunodeficiency Virus Types 1 and 2 in whole blood, serum and plasma. Earlier this month, the company announced that it received Premarket Application Approval from the U.S. Food and Drug Administration for the assay.

The Geenius HIV-1/HIV-2 Supplemental Assay, a faster and easier alternative to Western Blot and an objective alternative to the company's Multispot HIV-1/HIV-2 Rapid Test, offers a three-step procedure that produces clear, onscreen results in 30 minutes with full traceability. The Geenius Reader can then analyze and interpret reaction results for HIV-1 (p31 HIV-1 polymerase peptide, gp160 HIV-1 recombinant protein envelope, p24 HIV-1 recombinant protein core, and gp41 Group M and O HIV-1 peptide envelope) and for HIV-2 (gp 36 and gp 140 HIV-2 peptide envelope).

In designing the Geenius HIV-1/HIV-2 Supplemental Assay, Bio-Rad developers worked closely with the Centers for Disease Control and Prevention (CDC) to ensure the assay would align with the second step of the HIV testing algorithm that the CDC recommended in June 2014.

"We are pleased to receive the FDA Premarket Application Approval for what we consider to be a great improvement in HIV diagnostic testing," said Patrice Deletoille, Bio-Rad Vice President and General Manager, Infectious Disease Division.

Key Benefits:

  • Minimal training required – the clinician simply needs to dispense 15 µl of whole blood or 5 µl of serum/plasma into the cassette well, add 2 drops of buffer, wait 5-7 minutes, and then add 5 drops of buffer into a second well. After 20 minutes, the user can insert the cassette into the Geenius Reader for the automatic reading and interpretation.
  • Qualitative interpretation – interpretation of six individual HIV-1 and HIV-2 band results is provided along with a permanent record of the results and an image of the cassette. The data can later be uploaded to a Laboratory Information System.
  • User-friendly graphical interface – the interface on the notebook computer displays results of the interpretation of the six bands once the cassette is inserted into the reader. A unique 2D barcode on the cassette, read by the Geenius software, positively identifies each cassette, allowing the result and the patient ID to be recorded on a single document.
