Lavender-top tubes are most commonly used for which category of tests?

Lavender-top tubes contain EDTA, an anticoagulant that preserves blood cells and prevents clotting, making them ideal for hematology. This preservation allows accurate counting and analysis of blood cells, such as those done in a complete blood count and white blood cell differentials, as well as platelet evaluation and other cellular measurements. Chemistry and immunology commonly rely on serum or plasma tubes and different anticoagulants, while microbiology uses culture media rather than routine blood cell counts. So the primary use of lavender-top tubes is hematology.
