Why blood samples should be uncapped:


To maintain a contamination-free environment and prevent splashing of specimens on the technologist, it is vital to always uncapped specimens behind a splash shield. Proper mixing of blood with anticoagulant or other chemicals is essential, and therefore, all tubes must be gently flipped 5-8 times after filling (excluding red top tubes, which do not contain additives). Specimens can be centrifuged before the clotting process is completed, which will lead to a formation of a fibrin clot on top of the cell that is typically seen in hemolyzed specimens. It is essential to note that a damaged gel barrier could cause inaccurate serum and cell separation, resulting in skewed test results.
