Specific Gravity Fld QN is a quantitative test performed on body fluids, typically thoracentesis or paracentesis fluids. Specific gravity is defined as the ratio of the mass of body fluid to the mass of an equal volume of pure water. This test may be used to help distinguish exudates from transudative body fluids.
