The influence of packed cells volume (PCV)‎ and temperature on erythrocytes sedimentation rate (ESR)‎

الملخص EN

Erythrocytes aggregation is an important physiological phenomenon in the circulation of blood, and is a basic characteristic of normal blood that plays a major role in cardiovascular system especially in the microcirculation.

Blood samples have been taken from (30) volunteers (15 male, and 15 female), their ages (20-30) years.

The Erythrocytes Sedimentation Rate (ESR) for those subjects was measured at different Packed Cells Volume (PCV) (10%-25%), and also it was measured at different temperature (10oC-25oC).

The results show that there was a highly significant decrease (P<0.01) in ESR when the PCV increase and a highly significant increase (P<0.01) in ESR when the temperatures increase.

The conclusion from these results is that the ESR values were affected by each of PCV and temperature of the samples.
