Q. Is a vein finder useful?

Answer

Using a vein finder would make it easier for the phlebotomist to discover the vein, which would reduce the likelihood of pre-analytical error in the collection of specimens and the patient's associated suffering. Vein finders are optical devices that use the principle of Infrared light to create a picture, which is then superimposed over the target area. An individual's forearm, legs, or some other portion of the body of the choosing. Wherever there is blood, the Infrared or terahertz light that is shone onto this viewing area will be absorbed (the veins).
