concentration

 [kon″sen-tra´shun]
1. increase in strength by evaporation.
2. the ratio of the mass or volume of a solute to the mass or volume of the solution or solvent.
3. intense mental focus.
hydrogen ion concentration see hydrogen ion concentration.
mass concentration the mass of a constituent substance divided by the volume of the mixture, as milligrams per liter (mg/l).
mean corpuscular hemoglobin concentration (MCHC) the average hemoglobin concentration in erythrocytes, conventionally expressed in “per cent,” meaning grams per deciliter of red blood cells, obtained by dividing the blood hemoglobin concentration (in g/dl) by the hematocrit (in l/l): MCHC = Hb/Hct.
minimal alveolar concentration (MAC) the concentration of anesthetic that at a pressure of 1 atmosphere produces immobility in 50 per cent of subjects exposed to a noxious stimulus.
minimal bactericidal concentration (MBC) the lowest concentration of a given antibiotic required to kill a specific organism.
minimal inhibitory concentration (MIC) the lowest concentration of a given antibiotic that inhibits the growth of a specific organism.
molar concentration the concentration of a substance expressed in terms of molarity.
concentration test a test of renal function based on the patient's ability to concentrate urine; see also fishberg concentration test.

mean corpuscular he·mo·glo·bin con·cen·tra·tion (MCHC),

Hgb/Hct; the average hemoglobin concentration in a given volume of packed red blood cells, calculated from the hemoglobin therein and the hematocrit, in erythrocyte indices.

(MCHC) (mēn kōr-pŭs'kyū-lăr hē'mŏ-glō-bin kon'sĕn-trā'shŭn)
The average hemoglobin concentration in a given volume of packed red blood cells (RBC), calculated from the hemoglobin therein and the hematocrit (Hct), in RBC indices. The calculation is: MCHC = Hbg (g) × 100 ÷ Hct.

Mean corpuscular hemoglobin concentration (MCHC)

The measurement of the average concentration of hemoglobin in a red blood cell.

(MCHC) (mēn kōr-pŭs'kyū-lăr hē'mŏ-glō-bin kon'sĕn-trā'shŭn)
The average hemoglobin concentration in a given volume of packed red blood cells.

However, the results revealed significantly decreased values of total erythrocyte counts, packed cell volume, hemoglobin concentration, mean corpuscular hemoglobin concentration, serum total proteins and albumin while increased values of mean corpuscular volume was recorded in infected animals as compared to healthy ones.
The mean corpuscular volume (MCV, m3), the mean corpuscular hemoglobin (MCH, pg) and the mean corpuscular hemoglobin concentration (MCHC, %) were calculated using the following formulas (Jain, 1993):
Current guidelines for HS diagnosis include family history, splenomegaly, abnormal CBC indices [spherocytes identification; increase in MCHC (mean corpuscular hemoglobin concentration)], reticulocytes, and RDW (red cell distribution width); and decrease in Hb (hemoglobin) and MCV (mean cell volume), a negative direct antiglobulin test, increased bilirubin, and reticulocytosis.
Hematological values were established for total red blood cells, total white blood cells, packed cell volume, hemoglobin concentration, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, and differential leukocyte count.
The mean cell volume (MCV) and mean cell hemoglobin (MCH) are increased, with a mean corpuscular hemoglobin concentration (MCHC) within the reference range.
As a result, hematocrit, mean cell volume, and the mean corpuscular hemoglobin concentration will be affected.
Qualitative critical results for children (2) include the following: For hematology--Presence of blasts in the blood smear; new diagnosis or findings of leukemia; presence of drepanocytes (sickle cells); left shift, atypical lymphocytes, or abnormal reticulocyte count; abnormal erythrocyte indices (mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration).
Qualitative critical results for children 2 inclade the following: For hematology--Presence of blasts in the blood smear; new diagnosis or findings of leukemia; presence of drepanocytes (sickle cells); left shift, atypical lymphocytes, or abnormal reticulocyte count; abnormal erythrocyte indices (mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration).
Although the mean corpuscular hemoglobin concentration (MCHC) is described as the hemoglobin concentration per average red cell, this index is calculated as hemoglobin (g/L) divided by the hematocrit (L/L), thus representing the amount of hemoglobin (g or mol) in 1 L of red cells, with a unit as g/L or mol/L.
We found that the red blood cell count of apparently healthy people was 4.47[+ or -]0.21 x [10.sup.12] cells/L, the mean corpuscular volume was 94.51 [+ or -] 4.41 fL, and the mean corpuscular hemoglobin and the mean corpuscular hemoglobin concentrations were 31.17 [+ or -] 1.17 pg and 343.3 [+ or -] 8.23 pg, respectively.
