hemoconcentration

 [he″mo-kon″sen-tra´shun]
increase in the proportion of formed elements in the blood, as a result of a decrease in its fluid content.

he·mo·con·cen·tra·tion

(hē'mō-kon'sen-trā'shŭn),
Decrease in the volume of plasma in relation to the number of red blood cells; increase in the concentration of red blood cells in the circulating blood.

hemoconcentration

/he·mo·con·cen·tra·tion/ (-kon″sen-tra´shun) decrease of the fluid content of the blood, with increased concentration of formed elements.

hemoconcentration

[-kon′səntrā′shən]
Etymology: Gk, haima + L, cum, together with, centrum, center
an increase in the number of red blood cells resulting from either a decrease in plasma volume or increased production of erythrocytes. Also spelled haemoconcentration.

he·mo·con·cen·tra·tion

(hē'mō-kon'sĕn-trā'shŭn)
Decrease in the volume of plasma in relation to the number of red blood cells; increase in the concentration of red blood cells in the circulating blood.
Synonym(s): haemoconcentration.

hemoconcentration

increase in the proportion of formed elements in the blood, as a result of a decrease in its fluid content, e.g. in clinical dehydration.

Hemoconcentration was seen in more than 29% of the patients [Table 2].
Their RBC counts and Hgb concentrations were similar to those of neonate 520, but not due to hemoconcentration and dehydration.
Hemoconcentration has also been described in abalone experiencing handling stress (Ragg et al.
Differences in posture (standing, sitting, supine) cause changes in plasma volume resulting in hemoconcentration from supine to sitting to standing, and thereby increased analyte levels (25).
In the present study, the difference in hematological variables related to oxygen transport (RBCs, Hb, HCT) and calculated indices (MCV, MCH and MCHC) in response to basal and Zn supplemented diet possibly be related to hemodilution or hemoconcentration due to alteration in blood water content (Oti and Avoaja, 2005).
Warning signs that signal development of severe dengue include abdominal pain, persistent vomiting, mucosal bleed, hepatomegaly greater than 2 centimeters, clinical fluid accumulation, lethargy or restlessness, and hemoconcentration concurrent with a rapid decrease in platelet count.
5 mEq/L was considered hypokalemia, a platelet count below 100 000/[micro]L was considered significant thrombocytopenia, a serum calcium level below 7 mg/dL or a serum ionized calcium level below 1mmol/l was considered hypocalcemia, a blood glucose level below 47 mg/dL was considered hypoglycemia, more than 20% increase in the hematocrit level was considered hemoconcentration, growth of microorganisms in hemoculture combined with clinical findings was considered sepsis and an aspartate aminotransaminase (AST) value of >200U/L or an alanine aminotransaminase value of >100U/L was considered increased liver enzymes.
However, another factor besides sodium intake that affects osmolality is water consumption, via hemoconcentration and/or hemodilution.
Regarding the most-often used laboratory tests, the results do not coincide with others that found a greater frequency of hemoconcentration associated to a strong plasma capillary leakage (presence of ascites) and upon diagnosis of severe dengue (28).
This might lead to hypernatremia by hemoconcentration, but such a situation did not occur.
