index

 (pl. indexes, in´dices) (L.)
1. the numerical ratio of measurement of any part in comparison with a fixed standard.
Barthel index an objective, standardized tool for measuring functional status. The individual is scored in a number of areas depending upon independence of performance. Total scores range from 0 (complete dependence) to 100 (complete independence).
bleeding index any of various methods of assessing bleeding in the gingival sulcus before or after treatment.
body mass index (BMI) the weight in kilograms divided by the square of the height in meters, a measure of body fat that gives an indication of nutritional status.
cardiac index cardiac output corrected for body size.
cephalic index 100 times the maximum breadth of the skull divided by its maximum length.
citation index an index listing all publications appearing in a set of source publications (e.g., articles in a defined group of journals) that cite a given publication in their bibliographies.
Colour index a publication of the Society of Dyers and Colourists and the American Association of Textile Chemists and Colorists containing an extensive list of dyes and dye intermediates. Each chemically distinct compound is identified by a specific number, the C.I. number, avoiding the confusion of trivial names used for dyes in the dye industry.
erythrocyte indices the mean corpuscular volume, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration. These are all useful for evaluating anemias because they provide information on the size of the erythrocytes and the concentration of hemoglobin. Called also red cell or red blood cell indices.
glycemic index a ranking of foods based on the response of postprandial blood sugar levels as compared with a reference food, usually either white bread or glucose. See table.
left ventricular stroke work index (LVSWI) an index of the amount of work performed by the heart.
leukopenic index a fall of 1000 or more in the total leukocyte count within 1.5 hours after ingestion of a given food; it indicates allergic hypersensitivity to that food.
index Medicus a monthly publication of the national library of medicine in which the world's leading biomedical literature is indexed by author and subject.
opsonic index a measure of opsonic activity determined by the ratio of the number of microorganisms phagocytized by normal leukocytes in the presence of serum from an individual infected by the microorganism, to the number phagocytized in serum from a normal individual.
phagocytic index any arbitrary measure of the ability of neutrophils to ingest native or opsonized particles determined by various assays; it reflects either the average number of particles ingested or the rate at which particles are cleared from the blood or culture medium.
red blood cell indices (red cell indices) erythrocyte indices.
refractive index the refractive power of a medium compared with that of air (assumed to be 1).
short increment sensitivity index (SISI) a hearing test in which randomly spaced, 0.5-second tone bursts are superimposed at 1- to 5-decibel increments in intensity on a carrier tone having the same frequency and an intensity of 20 decibels above the speech recognition threshold.
therapeutic index originally, the ratio of the maximum tolerated dose to the minimum curative dose; now defined as the ratio of the median lethal dose (LD50) to the median effective dose (ED50). It is used in assessing the safety of a drug.
A group of values obtained from automated blood cell counters that provide information about the size—i.e., volume and the concentration—of Hb in RBCs

red cell indices

A group of values obtained from automated blood cell counters that provide information about size–ie, volume and concentration of Hb in RBCs; 3 abbreviations are found on the printouts of CBCs: MCH, MCHC, MCV
Red cell indices  
MCH Mean corpuscular hemoglobin A measurement of Hb/individual RBC Ref range 26-34 pg/red cell
MCHC Mean corpuscular hemoglobin concentration A value derived on automated–eg Coulter cell counters from measured parameters Ref range 31-36 g/dL
MCV Mean corpuscular volumes A calculated value for the average volume of peripheral RBCs Ref range 85-100 fL/cell

In summary, our results confirm that the traditional red cell indices (MCV, MCH, MCHC and RCDW) have a low specificity and sensitivity for distinguishing between iron-deplete and iron-replete patients, and also tend to be late indicators of ID.
Determination of frequency of thalassemia trait in a rural tertiary care hospital of India by using various red cell indices as screening tool.
Screening of ?-thalassaemia trait by means of red cell indices and derived formulae.
It has been concluded that the RBC count, MCV, and MCH are suitable for screening in a large population in resource poor areas and are the best discriminant functions among all red cell indices and continue to provide an essential support to the diagnosis and monitoring of hematological disorders.
We also indicate the importance of considering [alpha]-thalassemia in couples for whom red cell indices show microcytosis and hypochromia despite a lack of iron deficiency
This reduced rate of synthesis is responsible for the thalassaemic red cell indices associated with the inheritance of Hb E.
Red cell indices including mean corpuscular volume (MCV) and mean corpuscular haemoglobin (MCH) may confirm the presence of a microcytic hypochromic anaemia.
Measurements of hemoglobin, hematocrit, and red cell indices provide information about the appearance of the RBC, which aids in the classification.
It is also unclear which red cell indices should be tested for diagnosing the different types of anemia.
The hematology results indicated that between these different groups of mice there is considerable variation in formed element abundance and red cell indices. Interestingly, the nature of the variation strongly suggests there to be coordinate regulation of specific cell types, namely erythrocytes and platelets, as well as lymphocytes and monocyte.
The advent of automatic cell counters has made the red cell indices including mean cell volume (MCV) widely available.
