FAQ on Sodium Citrate Blood Specimen Collection Tubes
FDA says it is aware that the U.S. is experiencing significant interruptions in the supply of sodium citrate blood specimen collection tubes, often called light blue top tubes, used for coagulation testing. An agency Frequently Asked Questions says the shortage is due to an increase in demand and recent vendor supply challenges.
“FDA recommends healthcare and laboratory facilities develop and implement conservation strategies to minimize the use of these tubes and maintain the quality and safety of care for patients who need coagulation testing,” the notice says.
