What happens if you don't invert tubes for drawing blood?

If blood collection tubes are not inverted after drawing blood, it can lead to improper mixing of the blood with anticoagulants or additives present in the tubes. This may result in clot formation, which can interfere with accurate laboratory test results. Additionally, separation of components may occur, potentially affecting the quality and reliability of the sample. Proper inversion is crucial for ensuring that the blood is adequately mixed and that the tests performed yield accurate outcomes.
