The size difference causes the difference in colors. Colloidal gold is a sol or colloidal suspension of nanoparticles of gold in a fluid, usually water. [ 1 ] The colloid is coloured usually either wine red (for spherical particles less than 100 nm) or blue-purple (for larger spherical particles or nanorods). [ 2 ]
A complete blood count (CBC), also known as a full blood count (FBC), is a set of medical laboratory tests that provide information about the cells in a person's blood. The CBC indicates the counts of white blood cells, red blood cells and platelets, the concentration of hemoglobin, and the hematocrit (the volume percentage of red blood cells).
Live blood analysis (LBA), live cell analysis, Hemaview or nutritional blood analysis is the use of high-resolution dark field microscopy to observe live blood cells. Live blood analysis is promoted by some alternative medicine practitioners, who assert that it can diagnose a range of diseases. There is no scientific evidence that live blood ...
Silica nanoparticles induce coagulation through contact activation of coagulation factor XII (Hageman factor). [2] The silica particles are desiccants, which adsorb and hold water vapor. [ 3 ] This is used in the tubes so the blood adheres to the surface of the tiny silica particles and begins to clot.
Red blood cell distribution width (RDW), as well as various types thereof (RDW-CV or RCDW and RDW-SD), is a measure of the range of variation of red blood cell (RBC) volume that is reported as part of a standard complete blood count. [1] Red blood cells have an average volume of 80–100 femtoliters, but individual cell volumes vary even in ...
v. t. e. Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry ...
Red blood cell indices. Red blood cell indices are blood tests that provide information about the hemoglobin content and size of red blood cells. Abnormal values indicate the presence of anemia and which type of anemia it is. [1]
The test uses the principles of gel electrophoresis to separate out the various types of hemoglobin and is a type of native gel electrophoresis.After the sample has been treated to release the hemoglobin from the red cells, it is introduced into a porous gel (usually made of agarose or cellulose acetate) and subjected to an electrical field, most commonly in an alkaline medium.
