ACR score is a scale to measure change in rheumatoid arthritis symptoms. [1] It is named after the American College of Rheumatology . The ACR score is more often used in clinical trials than in doctor patient-relationships, as it allows a common standard between researchers.
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"), the ...
The ACR is the inverse of the application factor (AF). This makes it easier for regulators to visualize data as whole numbers rather than decimals. The AF is calculated by dividing the Maximum Acceptable Toxicant Concentration (MATC) by the Lethal Concentration that kills 50% of test organisms in an acute toxicity test .

Mean corpuscular volume (MCV) is the average volume of a red blood cell and is calculated by dividing the hematocrit (Hct) by the concentration of red blood cell count. [citation needed] = [] Normal range: 80–100 fL (femtoliter)
Absolute Category Rating (ACR) is a test method used in quality tests. [1] [2] The levels of the scale are, sorted by quality in decreasing order: Excellent; Good; Fair; Poor; Bad; In this method, a single test condition (generally an image or a video sequence) is presented to the viewers once only. They should then give a quality rating on an ...
Activated clotting time (ACT), also known as activated coagulation time, is a test of coagulation. [1] [2]The ACT test can be used to monitor anticoagulation effects, such as from high-dose heparin before, during, and shortly after procedures that require intense anticoagulant administration, such as cardiac bypass, interventional cardiology, thrombolysis, extra-corporeal membrane oxygenation ...
Modalities applied to measurement of ejection fraction is an emerging field of medical mathematics and subsequent computational applications. The first common measurement method is echocardiography, [7] [8] although cardiac magnetic resonance imaging (MRI), [8] [9] cardiac computed tomography, [8] [9] ventriculography and nuclear medicine (gated SPECT and radionuclide angiography) [8] [10 ...
