The company has collaborated with Receptors and discovered an improvement in sample preparation technology which will minimize false-positive and false-negative test results.

PositiveID said its sample prep application readily identifies the ideal sample preparation environment with the right balance of analyte concentration and purification (i.e. to isolate flu virus from a sample).

PositiveID also intends to expand its diagnostic testing platform to other healthcare and homeland security applications and is focused on the convergence of rapid biological testing with airborne homeland security threats.
