ESR tube is generally used for ESR detection. This type of blood collection tube uses a 0.129mol/L sodium citrate buffer system for anticoagulation of blood samples. It is used to detect blood sedimentation rate by"Weissner's sedimentation method". The volume ratio of anticoagulant to blood is 1:4. It includes dynamic ESR tubes that provide direct specimens and 75mm short tubes that require specimen transfer. The dynamic ESR tube can be directly put on the shelf for reading after blood collection or applied to the ambulatory erythrocytesedimentation rate instrument.
