Biorise sodium citrate tube is used to collect venous blood for coagulation testing.

Anticoagulant: trisodium citrate dehydrate, concentration:
0,129 mol/L — 3,80% (38,0 g/L). The ratio of blood to sodium citrate is 9:1.

The anticoagulant properties of citrate are expressed by citrate ions forming calcium citrate complexes with Са2+ ions, effectively disrupting the blood clotting mechanism.

Range of application: hemostasis system diagnostics.
Specimen: citrated plasma.
Centrifugation conditions: 2000-2500 g for 15 minutes.

It is very important to maintain the correct blood to the anticoagulant ratio for the citrated sample.

A lack of citrate in the sample leads to micro clot formation and/or coagulation of the sample.

An excess of citrate leads to the distortion of analysis results due to calcium-binding.

Immediately after the specimen is collected, gently invert the citrate tube at least 5 times to mix thoroughly, preventing micro clot formation.
