Which one among the following separation techniques is used for blood tests in diagnostic laboratories?

Correct option is C

The Correct answer is (c) Centrifugation. Centrifugation is a widely used separation technique in diagnostic laboratories, particularly for blood tests. It works by spinning blood samples at high speeds, creating a centrifugal force that separates the components of blood based on their density. The heavier components, such as red blood cells, move to the bottom, while lighter components, like plasma, remain at the top. This process helps in analyzing different components of blood for diagnostic purposes, such as checking plasma glucose levels, separating blood cells, or detecting abnormalities. Information Booster: (a) Filtration: This is a physical method used to separate solids from liquids or gases by passing the mixture through a filter medium that allows only the liquid or gas to pass, while the solid particles are retained. (b) Chromatography: This is a technique used to separate the components of a mixture based on their different affinities for a stationary phase (such as paper or a solid column) and a mobile phase (such as a solvent). It is widely used in chemistry for separating and analyzing complex mixtures. (d) Crystallization: This is a separation process used to purify substances by forming solid crystals from a solution. It is often used to separate a solid solute from a liquid solvent, as the solute comes out of the solution and forms a crystalline structure when the solvent evaporates.
