How many times do you invert the tube of blood so it will not clot?
Inverting a tube of blood will not prevent it clotting. Only an anticoagulant will do this, the different coloured tops on blood samples refer to the different anticoagulants or lack thereof inside the tubes. Inverting the tube is done to mix blood samples that have settled gently inverting the tube 6-10 times is enough to mix the blood. Inverting the tube more than this or doing it too violently could trigger clotting even in a sample containing an anticoagulant.
When delivering blood samples to a laboratory they should always be transported inside?
There are many blood sample tubes. The most basic one would be the Red top tube (red top blood sample tube). Or the Light Blue coagulation tube - NOTE: If coag tests only are ordered AND you are using a butterfly, draw a discard tube to collect the air in the tubing. Failure to do so will result in a short draw which will be rejected by the lab. The blood samples can be delivered to the lab in these (tube) containers.
