Methodology
Photopheresis or extracorporeal photopheresis (ECP) is a photoimmune therapy where white blood cells
are separated from whole blood via apheresis, combined with a
photoactive drug (8-methoxypsoralen) and then exposed to ultra
violet A (UVA) light. All blood
components, including the treated white blood cells are returned to
the patient.
The Buffy Coat is passed through the Photoactivation Module where
the drug is activated with a precise amount of UVA light determined by the characteristics of the
individual patient's Buffy Coat. After photoactivation, the Buffy
Coat is promptly returned to the patient bloodstream.
