Red blood cell distribution width is a way for scientists to measure red blood cell volume and size. When red blood cells are larger than normal, that could indicate a problem. The reference range for RDW is as follows: RDW-SD: 29-46 fL.
energy expenditure using doubly labelled water Iso-Analytical provides a full range of analytical services for customers wishing to determine Energy Expenditure using doubly labelled water. The Doubly Labelled Water (DLW) method uses the natural occurring stable isotopes of water (D 2 O and H 2 18 O) to assess energy expenditure, body composition and water flux in humans and animals. The DLW method is entirely safe and non-restrictive, requires only periodic sampling of body fluids and is well suited for measurement of energy expenditure in free-living or hospitalized patients.
