Sodium citrate 1:4 tube

Purpose of vacuum blood collection vessel:

The erythrocyte sedimentation rate was measured by Wechsler's sedimentation method * *, blood was collected and anticoagulated, and the volume ratio of anticoagulant to blood was 1:4.

eight × 120mm sedimentation tube: sedimentation meter * tube. The additive is sodium citrate, which is used for blood sample collection and anticoagulation during blood cell sedimentation rate inspection.

thirteen × 75mm blood sedimentation tube: it is generally used for ESR detection. The concentration of sodium citrate is 3.2% and 3.8%, and the volume ratio of anticoagulant to blood is 1:4. When the ratio of anticoagulant is too high, the blood will be diluted to accelerate ESR. Heparin anticoagulants can change

The potential of red blood cells, so it is not suitable for the detection of erythrocyte sedimentation rate.
