If you draw blood, proper tube handling is important if the lab has any hope of extracting an accurate test result from the blood inside. With advice from Randy Red Top, one of the most commonly used blood collection tubes, this video continues our "If Tubes Could Talk" series. He's a little grumpy, but the advice he offers on how long he takes to clot, centrifugation time and speed, stability and preserving potassium results to be worth a listen.
