Before Using

1. Check the tube cover and tube body of the vacuum collector. If the tube cover is loose or the tube body is damaged, it is prohibited to use.

2. Check whether the type of blood collection vessel is consistent with the type of specimen to be collected.

3. Tap all blood collection vessels containing liquid additives to ensure that the additives do not remain in the head cap.

Storage Conditions

Store tubes at 18-30°C, humidity 40-65% and avoid exposure to direct sunlight. Do not use tubes after their expiration date indicated on the labels.

Hemolysis Problem

Precautions:

1) Take blood from a vein with a hematoma. The blood sample may contain hemolytic cells.

2) Compared with the additives in the test tube, the blood collection is insufficient, and hemolysis occurs due to the change of osmotic pressure.

3) The venipuncture is disinfected with alcohol. Blood collection is started before the alcohol is dry, and hemolysis can occur.

4) During skin puncture, squeezing the puncture site to increase blood flow or sucking blood directly from the skin can cause hemolysis.
