Point-of-care (POC) devices can be used in the field in a variety of situations. (A) Point-of-care glucose meter being set up on a boat (photograph by Lisa Thompson). (B) Protective cases, similar to the one shown, are useful for ensuring that POC devices are not damaged by the elements (photograph by Lisa Thompson). (C) Point-of-care devices, such as this glucose meter, can be used in laboratory trials to obtain immediate results on the condition of the individual (photograph by Petra Szekeres). (D) Some POC devices, such as the i-STAT, can obtain multiple blood parameters to be measured from one sample (photograph by John Mandelman).
