>> FAQ
Q1. What is the Difference Between a Capillary Tube and a Micro Collection Tube?
A: · Structural difference:
Capillary blood collection tube is composed of capillary tube, central crossed rubber cap, and a micro tube.
Micro collection tube is composed of screw cap and plastic tube with integrated collection scoop.
· Operational difference:
Capillary blood collection tube is collected by micro tube with capillary action that the blood will flow into the tubes against the effect gravity. The cap of capillary tubes is made of rubber and has a "valve" on it. During blood collection, the collection strap can be penetrated through the rubber cover without opening the cover.
The micro blood collection tube uses integrated collection scoop to collect blood.
· Application:
Capillary blood collection tube and micro blood collection tube are both used for obtaining specimens in infants or in adults where venipuncture is difficult. But the capillary blood collection tube is used more convenient.
Q2. How Are Micro Containers Collected Blood?
A: 1. Select the appropriate microtainers for the specimens to be collected. Any microtainers
containing additives should be tapped to dislodge additives from the walls and top.
2. Wash hands and put on gloves.
3. Position the patient with the arm extended to form a straight-line form shoulder to wrist.
4. Do not attempt a capillary puncture more than twice. The micro blood collection tube uses integrated collection scoop to collect blood.
