ABSTRACT
Intravascular laser irradiation of blood (ILIB) is a systemic low-
level laser modality that aims the irradiation of blood. Discovered
by Russian scientists in the 1970s, ILIB consists of laser blood
irradiation through a fiber optic inserted in a vascular channel,
usually a vein in the forearm. ILIB irradiation lasts for about 30
min, which is assumed to be sufficient time for the whole blood to
receive light, enabling systemic effect. Thus, blood components such
as blood lipids, platelets, immune system, and red cells are the main
targets.
