A micrometer, sometimes known as a micrometer screw gauge (MSG), is a device incorporating a calibrated screw widely used for accurate measurement of components [1] in mechanical engineering and machining as well as most mechanical trades, along with other metrological instruments such as dial, vernier, and digital calipers.
Blood-related parameters are listed in a blood test. Electrocardiograph records the electrical activity of the heart; Glucose meter for obtaining the status of blood sugar. Sphygmomanometer, a blood pressure meter used to determine blood pressure in medicine. See also Category:Blood tests
The most successful and important application of the Coulter counter is in the characterization of human blood cells. The technique has been used to diagnose a variety of diseases and is the standard method for obtaining red blood cell counts (RBCs) and white blood cell counts (WBCs) as well as several other common parameters.
used in photochemical analysis and quantitative estimation of substances such as blood sugar, creatinine, and hemoglobin. Burette: used to measure the amount of acid or alkali used in titration: General laboratory stands, racks, filter paper, reagents, etc. Induction coils: as a source of high voltage electricity Cathode ray oscilloscope ...
A blood test is a laboratory analysis performed on a blood sample that is usually extracted from a vein in the arm using a hypodermic needle, or via fingerprick. Multiple tests for specific blood components, such as a glucose test or a cholesterol test , are often grouped together into one test panel called a blood panel or blood work .
The hemocytometer (or haemocytometer, or Burker's chamber) is a counting-chamber device originally designed and usually used for counting blood cells. [1] The hemocytometer was invented by Louis-Charles Malassez and consists of a thick glass microscope slide with a rectangular indentation that creates a precision volume chamber.
Coagulometers require blood samples that have been drawn in tubes containing sodium citrate as an anticoagulant. These are used because the mechanism behind the anticoagulant effect of sodium citrate is reversible. Depending on the test, different substances can be added to the blood plasma to trigger a clotting reaction.
A more accurate value of systolic blood pressure can be obtained with a sphygmomanometer and palpating the radial pulse. [11] Methods using constitutive models have been proposed to measure blood pressure from radial artery pulse. [citation needed] The diastolic blood pressure cannot be estimated by this method. The American Heart Association ...
