This test is FDA approved and is
intended for in vitro diagnostic use.
This test is performed pursuant to an
agreement with Roche Molecular Systems.
This test is performed by real-
time PCR using the Roche LightCycler
instrument. The product of PCR is
detected by fluorescence produced when
a specific pair of probes, each labeled
with a fluorophore, binds to the PCR
product in close proximity. |
