Preparation of Serum and Plasma for Testing

Serum

Clear liquid from clotted blood, without clotting factors.

Plasma

Straw-colored liquid, transports blood cells and substances.

Hematopoiesis

Process of blood cell formation in the body.

Erythrocytes

Red blood cells responsible for oxygen transport.

Leukocytes

White blood cells involved in immune response.

Platelets

Cell fragments aiding in blood clotting.

Centrifugation

Process to separate components by density.

Icteric Serum

Yellow serum due to elevated bilirubin levels.

Bilirubin

Substance that can interfere with laboratory tests.

Hemolyzed Serum

Serum with leaked intracellular substances from cells.

Lysis of Cells

Breakdown of cells leading to hemolysis.

Lactescence

Milky serum due to elevated chylomicrons post-meal.

TAG Level

Triglyceride level indicating lipemic serum condition.

Plasma Proteins

Proteins in plasma, including albumin and globulin.

Albumin

Most abundant plasma protein, 60% of total proteins.

Globulin

Plasma protein, 35% of total proteins, includes antibodies.

Fibrinogen

Plasma protein, 4% of total proteins, essential for clotting.

Electrolytes

Minerals dissolved in serum, vital for body functions.

Closed Circulatory System

Blood circulates within vessels, not open to environment.

Short Life Span

Blood cells are continuously replaced in the body.

Common Interferences

Factors causing unacceptable serum or plasma specimens.

Clinical Chemistry

Field studying chemical processes in the body.
