Sterile vacuum blood collection tubes are for serum determination. Tubes with a BD Hemogard™ closure incorporate a plastic shield that protects lab personnel from contact with blood on the stopper or around the outer rim of the tube, and from potential splattering when tube is opened. The closure's rubber stopper is recessed inside the plastic shield to isolate blood drops left by the needle.
