Are there special considerations for phlebotomy when using the PAXgene Blood ccfDNA Tube (blood collection set, discard tube, positioning of the tube, issues with short draws, etc.)?

Yes. Following a standard phlebotomy protocol, blood is collected into the evacuated tube using a blood collection set and a standardized needle holder that can accommodate a 16 mm diameter tube. Make sure that blood has stopped flowing into the tube before removing the tube from the holder.

For more information on phlebotomy technique, please refer to the PAXgene Blood ccfDNA Tube Product Circular under the Resources tab.
