Sedimentation Rate (Sed Rate)

The sedimentation rate (sed rate) blood test measures how quickly red blood cells (erythrocytes) settle in a test tube in one hour. The more red cells that fall to the bottom of the test tube in one hour, the higher the sed rate. When inflammation is present in the body, certain proteins cause red blood cells to stick together and fall more ...

7.3.2: Chemical Sedimentation

Silica (SiO 2 ), in the form of chert, is the only silicate mineral that commonly forms a chemical sedimentary rock. Gypsum (CaSO 4 •2H 2 O), anhydrite (CaSO 4 ), halite (NaCl), and sylvite (KCl) consist of common elements. Ggypsum and anhydite have high solubilities; halite and sylvite have even higher solubilities.
