Description

With sodium citrate (3.2% 1:9 0.109mmol/L)

Test tubes with sodium citrate are used to collect venous blood for coagulation testing.

Range of application: hemostasis system diagnostics.



Test tubes with sodium citrate are used to collect venous blood for coagulation testing.

Anticoagulant: trisodium citrate dehydrate, concentration:
0,109 mol/L — 3,20% (32,0 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 anticoagulant ratio for the citrate sample.

A lack of citrate in the sample leads to microclot 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 microclot formation.
