Serum sample, selected and control sera stored in various environment indicated, ie.,
refrigerating or room temperature, were analysed to evaluate the effecters of evaporation
due to storing condition on sample weight and analytical values.
The storing period choice4 are 4 hours and the results analyzed are ass as follow :
1) The serum sample stored in room air revealed 13.39% decrease in weight and 7.1%
decrease in refrigerator.
2) The analytical value of the serum sample and control sera stored in room air
revealed obvious increase ie., 24.4∼24.2% in SGOT., 16.6∼ 29.4% in SGPT., 25.8-8.2%
in Alk. phosphatase, 9.7∼11.7% in total protein, 13.1∼19.4% in albumin and 15.6∼3.2%
in cholesterol.
The more striking alterations are noted in enzyme items of serum than in
non-enzyme than in non-enzyme items.
3) The serum and control sera sample store4 in refrigerator revealed increased value
of 9.8∼10.3% in SGOT., 6.3∼5.3% in SGPT., 1.1∼2.5% in Alk, phosphatase, 2.7∼1.5%
in total protein, 5.2∼4.5% in albumin and 3.0∼5.0% in cholesterol.
4) It is, therefore, recommended that should b e stored the serum samples in the
refrigerator until tested which obviously alleviate the evaporative loss of weight and
analytical variations.
