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

Usefulness of Red cell Indices in Differentiating Microcytic Hypochromic Anemias.
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.
Laboratory data included haemoglobin (Hb) and red cell indices (MCV and MCH) obtained using an automated analyser (Sysmex XE-2100, Sysmex Corporation, Japan).
Age-related changes in full blood count and red cell indices have not been clearly defined.
Hemoglobin levels and red cell indices including MCV, MCH, and MCHC were estimated in Madina Teaching Hospital laboratory by KX21NTM automated hematology analyzer (Sysmex) which is reliable and give accurate results through the use of automatic floating discriminators.
Blood in the EDTA tubes was used to determine haemoglobin (Hb) concentration, erythrocyte count and red cell indices by Haematology Analyser Sysmex KX -21.
15] For the clinician, it is important to interpret the CHr in the context of the patient's other clinical and laboratory investigations including red cell indices, vitamin B12, folate levels and findings on haemoglobin electrophoresis.
Red cell indices (MCH, MCHC, and MCV), red cell distribution width, and white cell count decreased continuously in infancy and stabilized afterward without substantial sex-specific differences.
Blood samples (2 cc) anticoagulated in ethylenediami-netetraacetic acid (EDTA) were run in an automated hematology analyzer (Abacus) for counts and red cell indices.
A study of histogram can become a new parameter along with red cell indices in the diagnosis of anemias.
Routine investigations including complete blood count (CBC), erythrocyte sedimentation rate (ESR), red cell indices, platelet count and reticulocyte count were carried out on all subjects.
