Blood plasma carries blood cells nutrients hormones and others urine waste product secreted by the kidney interstitial fluid fluid that are located in between cells. Total body water TBW encompasses extracellular interstitial.
Often these fluids are tested instead of blood because they can give more direct answers to what may be going on in a particular part of the body. Laboratory testing can be performed on many types of fluids from the body other than blood. In medicine the term extravascular body fluid is used with specific reference to all body fluids other than blood.
Choose from 500 different sets of the body fluids chemistry flashcards on Quizlet. However understanding the clinical utility of these analytes is critical because laboratories must address the analytic and clinical validation requirements while educating clinicians on proper test utilization.
