Abstract :

The transportation of laboratorial samples with pneumatic tube system spends less time than when were handled by courier. Pneumatic tube system produces minor vibrations on sample due to the velocity changes during transportation and may cause changes on the blood cells and haemolysis. The aim of this study is to know the effect of sample transportation with pneumatic tube on blood cells and its effect on hemolysis. A cross sectional study was performed at Dr. Wahidin Sudirohusodo Hospital, Makassar in July 2013. Routine blood, electrolyte and LDH were tested in 12 out-patients. The researchers collected two (2) samples, for each EDTA tube (routine blood tests) and serum (electrolyte and LDH). The samples were transported using pneumatic tube and the paired samples were sent by courier. The result then were analyzed with Paired T-Test. There were no significant difference of routine blood test results between samples sent by pneumatic tube and courier except RDW. RDW were higher in samples which were sent by pneumatic tube compared to those brought by the courier (18.72±2.70% vs 17.83±2.36%, p=0.007). The electrolyte levels sent by both methods there were no significant difference, but the LDH levels were higher in samples sent by pneumatic tube (472.08±100.44 U/L vs 331.25±94.19 U/L, p=0.000). Based on this study, in common can be concluded that the pneumatic tube system does not effect on the routine blood test results, except on RDW and does not cause changes due to haemolysis (on electrolyte) except the LDH levels elevates. So based on this study, it is recommended to send samples for LDH test only by courier Pengiriman sampel laboratoris dengan sistem pneumatic tube memudahkan dan mempercepat tibanya dari tempat pengambilan ke laboratorium. Sistem pneumatic tube menyebabkan getaran kecil di sampel akibat perubahan kecepatan selama pengangkutan, sehingga dapat menyebabkan perubahan sel darah dan hemolisis. Tujuan penelitian ini untuk mengetahui pengaruh pengiriman sampel dengan sistem pneumatic tube terhadap sel darah dan terjadinya hemolisis. Penelitian ini merupakan kajian potong silang, dilakukan di RS. Dr. Wahidin Sudirohusodo, Makassar pada bulan Juli 2013. Uji darah rutin, elektrolit dan LDH dilakukan pada 12 pasien rawat jalan. Pengambilan dilakukan sebanyak dua (2) tabung dengan EDTA (uji darah rutin) dan yang tanpa antikoagulan (uji elektrolit dan LDH) untuk setiap pasien. Sampel dikirim dengan pneumatic tube dan pasangan sampelnya dikirim dengan petugas antar dan hasilnya dianalisis dengan Uji T Berpasangan. Di hasil uji darah rutin dari sampel yang dikirim dengan pneumatic tube maupun dengan petugas antar tidak ditemukan perbedaan bermakna, kecuali di hasil RDW. Hasil RDW di sampel yang dikirim dengan pneumatic tube sedikit lebih tinggi dibandingkan dengan yang dibawa petugas antar (18,72±2,70% vs 17,83±2,36%, p=0,007). Hasil elektrolit di kedua cara pengiriman sampel tersebut tidak terdapat perbedaan, tetapi kadar LDH lebih tinggi secara bermakna di pengiriman dengan pneumatic tube (472,08±100,44 U/L vs 331,25±94,19 U/L, p=0,000). Berdasarkan kajian ini, penggunaan pneumatic tube tidak mempengaruhi hasil darah rutin secara umum kecuali RDW dan tidak menyebabkan perubahan akibat hemolisis (uji elektrolit) kecuali di LDH. Oleh karena itu, pengangkutan sampel untuk uji LDH disarankan dikirim dengan petugas antar.
