Abstract

This study was conducted to determine the valid time for accurate detection of complete blood cell count (CBC) in pig blood using an automatic blood corpuscle analyzer (Hemavet 950FS). Blood samples were collected from 34 pigs (Duroc) with a 60 kg (${\pm}3.5$) body weight. Ten specimens with CBC parameters in normal range and with no hemolysis were selected among 34 samples and used in this study. Regarding leukocytes parameters, white blood cell (WBC), neutrophil (NE), and lymphocyte (LY) counts showed a low daily variation (coefficient of variation, CV), whereas monocyte (MO), eosinophil (EO), and basophil (BA) CVs were significantly high (19.7, 56.9, and 53.3%, respectively). On the other hand, all parameters of erythrocytes and thrombocytes showed stable daily variation. All parameters of leukocytes and thrombocytes were significantly reduced as storage time passed (P<0.01 or 0.001), except for lymphocytes (P=0.535). However, no significant differences were observed in parameters of erythrocytes from blood up to 120 hours. From above results, we assert that Hemavet 950FS is useful in analyzing CBC, except for MO, EO, and BA. For accurate detection of leukocyte and thrombocyte parameters, analysis should be performed within 4 hours after blood collection when using Hemavet 950FS. On the other hand, parameters of erythrocytes could be stably detected for at least 120 hours after blood collection.

본 연구는 자동혈구분석기 Hemavet 950FS를 이용한 돼지 혈액 내 혈구분석의 유효성을 검증하고, 정확한 분석을 위한 유효시간을 결정하기 위하여 실시하였다. 분석시료는 체중 60 kg (${\pm}3.5$)의 Duroc 종 34두로부터 채취하였으며, 이들 중에서 분석치가 정상범위를 벗어나거나 용혈이 발견된 시료는 연구에서 제외하고 최종적으로 10개의 시료를 본 연구에 이용하였다. 임의의 하나의 시료에 대해 10회 연속분석을 통하여 일내변동을 조사한 결과, leukocytes계 혈구들 중에서 백혈구, 호중구, 림프구에서는 낮은 일내변동으로 분석의 유효성이 인정되었으나, 단핵구, 호산구, 호염구에 있어서는 큰 변동을 나타내었다. 이와 반면에 erythrocytes 및 thrombocytes계 혈구들의 모든 지표들은 안정적인 일내변동이 관찰되었다. 채혈 후 시간 경과에 따른 혈구변화를 분석한 결과 leukocytes계 혈구 및 thrombocytes계 혈구는 시간경과에 따라 검출농도가 유의적으로 감소되는 것으로 관찰되었다. 반면, erythrocytes계 혈구들은 채혈 후 120시간까지는 안정적으로 분석이 가능한 것으로 나타났다. 본 연구의 결과를 종합하면, Hemavet 950FS는 돼지의 혈액 내에서 단핵구, 호산구, 호염구를 제외하고 일반 혈구분석에 유용한 것으로 판단된다. 또한, leukocytes 및 thrombocytes계 혈구들에 대한 정확한 분석을 위해서는 채혈 후 4시간 이내에 분석이 이루어져야하며, erythrocytes계 혈구들은 채혈 후 120시간까지는 안정적으로 검출이 가능한 것으로 사료된다.
