red tops

Red tops are special blood collection tubes with a red-colored cap, used in laboratories to draw blood for testing. They contain no additives or anticoagulants, allowing blood to clot naturally. Once the blood clots, the serum (the liquid part) can be separated and used for various diagnostic tests. Red top tubes are commonly used for blood chemistry tests, antibody screening, and other diagnostic purposes where serum analysis is needed. Their simple design helps ensure the quality of the sample for accurate laboratory results.
