Clinical parameters
Browse physiological and laboratory parameters together with specimen, method, unit, population context and curated reference bands.
Ranges are source-, method-, specimen-, age-, sex- and population-specific. They are educational reference data, not a substitute for the reporting laboratory or clinical judgement.
Total Lung Capacity
AMW:PARAM:135009The volume of air contained in the lungs at the end of a maximal inspiration. It is the equivalent to each of the following sums: VITAL CAPACITY plus RESIDUAL …
Transition Temperature
AMW:PARAM:190010The temperature at which a substance changes from one state or conformation of matter to another.
Urine Albumin Concentration
AMW:PARAM:125033Urine Creatinine Concentration
AMW:PARAM:125034Urine Osmolality
AMW:PARAM:125039Urine Protein Concentration
AMW:PARAM:125036Urine Protein-to-Creatinine Ratio
AMW:PARAM:125037Vapor Pressure
AMW:PARAM:190007The contribution to barometric PRESSURE of gaseous substance in equilibrium with its solid or liquid phase.
Venous Pressure
AMW:PARAM:105009The blood pressure in the VEINS. It is usually measured to assess the filling PRESSURE to the HEART VENTRICLE.
Ventilation-Perfusion Ratio
AMW:PARAM:135017The ratio of alveolar ventilation to simultaneous alveolar capillary blood flow in any part of the lung. (Stedman, 25th ed)
Ventricular Pressure
AMW:PARAM:105015The pressure within a CARDIAC VENTRICLE. Ventricular pressure waveforms can be measured in the beating heart by catheterization or estimated using imaging tech…
Viral Load
AMW:PARAM:125017The quantity of measurable virus in a body fluid. Change in viral load, measured in plasma, is sometimes used as a SURROGATE MARKER in disease progression.
Viscosity
AMW:PARAM:190013The resistance that a gaseous or liquid system offers to flow when it is subjected to shear stress. (From McGraw-Hill Dictionary of Scientific and Technical Te…
Vital Capacity
AMW:PARAM:135013The volume of air that is exhaled by a maximal expiration following a maximal inspiration.
Waist-Hip Ratio
AMW:PARAM:160020The waist circumference measurement divided by the hip circumference measurement. For both men and women, a waist-to-hip ratio (WHR) of 1.0 or higher is consid…
