👉 The Edward Fluid, also known as Edward's Fluid, is a colloidal suspension of red blood cells, proteins, and other cellular components in plasma, named after the British physician William Edward James. Discovered in 1884, it is characterized by its unique optical properties, notably birefringence, where it exhibits different refractive indices when viewed under polarized light. This fluid is primarily found in the peripheral blood of healthy individuals, with concentrations typically ranging from 1% to 4%. The presence and concentration of Edward Fluid can serve as an indicator of the overall health of the blood, with higher levels potentially signaling hemolytic anemia, hemolysis, or other hematological disorders.
