cobas® Plasma Separation Card

cobas®  Plasma Separation Card

Redefine the reach of reliable testing

As the world’s leading provider of HIV viral load testing, Roche is committed to increasing access to reliable HIV testing.

The cobas® Plasma Separation Card is a stable and easy-to-use sample collection device for HIV plasma viral load, simply spot a small amount of blood on the card, transport to a lab where HIV diagnostic tests can be performed. By providing a small amount of a patient’s blood from a fingertip, this specially designed card simplifies blood collection and sample transportation.

Innovation in HIV testing

The Card fundamentally changes the way plasma samples are taken and processed and allows for reliable quantitative testing of patients with HIV living in remote areas-even areas of extreme heat and humidity-while meeting WHO requirements for determining HIV viral load prior to setting treatment.

Intended use

 

cobas® HIV-1 is an in vitro nucleic acid amplification test for the quantitation of human immunodeficiency virus type 1 (HIV-1) in EDTA plasma or from a cobas® Plasma Separation Card (PSC) dried plasma spot of HIV-1-infected individuals.

This test is intended for use in conjunction with clinical presentation and other laboratory markers for the clinical management of HIV-1-infected patients. This test can be used for confirmation of HIV-1 infection in antibody reactive individuals and to assess patient prognosis by measuring the baseline HIV-1 level or to monitor the effects of antiretroviral therapy by measuring changes in HIV-1 RNA levels during the course of antiretroviral treatment.
