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.

mean corpuscular hemoglobin concentration (MCHC),

an estimation of the concentration of hemoglobin in grams per 100 mL of packed red blood cells, derived from the ratio of the hemoglobin to the hematocrit. The normal MCHC is between 32% and 36% in adults and children and 32% and 34% in newborns.

(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.

1) The assessment of iron deficiency anemia (IDA) is incomplete without demonstrating iron-deficient erythropoiesis, by looking at the red cell indices (mean corpuscular volume, mean cell haemoglobin and mean cell haemoglobin concentration (MCV, MCH and MCHC)).
The anaemia is usually normocytic, with normal mean cell volume (MCV), and normochromic with normal mean cell haemoglobin (MCH), but in 20-50% of patients it is mildly microcytic (reduced MCV) and hypochromic (reduced MCH).
