To ensure accurate and reliable results in laboratory analyses, sample collection, storage, and transport must be carried out properly. The guide below outlines the steps for using blood collection tubes and the key points to keep in mind.
Fill the tube three-quarters full with blood; do not shake it to prevent hemolysis, and let it stand at room temperature for 30–40 minutes.
Centrifuge the tubes for 15 minutes at 2500 rpm, and transfer the serum samples to 1.5 mL microtubes using a pipette.
If a centrifuge is not available, serum will separate from the samples after 3–4 hours at room temperature.
When transferring serum samples to microtubes, fill the tube to two-thirds capacity.
It is recommended that you ship serum samples in a foam box containing ice packs.
For long-term storage, serum samples should be stored at -20°C, and repeated freezing and thawing should be avoided.

Centrifuge the tubes for 15 minutes at 2500 rpm, and transfer the serum samples to 1.5 mL microtubes using a pipette.
In the centrifuged tubes, the separator gel will form a barrier between the blood and the serum.
When transferring the serum samples to microtubes, fill the tube to two-thirds capacity.
It is recommended that you ship the serum samples in a foam box containing an ice pack.
For long-term storage, serum samples should be stored at -20°C, and repeated freeze-thaw cycles should be avoided.
Fill the tube three-quarters full with blood; do not swirl, but gently invert it 4–5 times.
Store at 2–8°C; prevent freezing during storage and shipping.
It is recommended that you ship the samples in the same tube inside a foam box containing an ice pack.
If plasma is required, centrifuge the tubes for 15 minutes at 2500 rpm.
Transfer the plasma samples to 1.5 mL microtubes using a pipette.
For long-term storage, plasma samples should be stored at -20°C, and repeated freeze-thaw cycles should be avoided.
Hemolizli numunelerin çalışılması tavsiye edilmemektedir. Hemolizi engellemek için numune alma, bekletme, santrifüjleme ve sevk adımlarının dikkatli uygulanması önemlidir. Uzun süre bekleyen serum veya plazma numunelerinde proteinler çökebileceği için, başka tüpe aktarılmadan önce numune karıştırılmalı ve homojen görünüm elde edilmelidir.
