👉 Measured fluid, also known as total body water (TBW), refers to the total amount of water present in the human body, encompassing all its various compartments. This includes water in the intracellular space (within cells), extracellular fluids (such as plasma, interstitial fluid, and cerebrospinal fluid), and water in the gastrointestinal tract, lungs, and other tissues. Measuring TBW provides insight into an individual's hydration status, electrolyte balance, and overall physiological function. It is typically expressed in milliliters (mL) or kilograms (kg). Variations in measured fluid can indicate conditions such as dehydration, overhydration, or changes in health status, making it a valuable biomarker for assessing hydration and overall health.
