<em>Plasma is </em><em>freed</em><em> from </em><em>the</em><em> cells by</em><em> the</em><em> centrifugation. </em><em>Clotting of blood is prevented by the </em><em>addition of an anticoagulant </em><em>directly</em><em> after </em><em>the </em><em>taking </em><em>of</em><em> blood.</em>

<em>The l</em><em>ithium or sodium heparin is used as an anticoagulant.</em>

<strong><em>Heparin</em></strong><em> is a natural anticoagulant </em><em>which </em><em>present</em><em>s</em><em> in </em><em>any healthy</em><em> body.</em>

<em>Powdered heparin is applied to the inner layer of the test tube. Immediately after taking</em><em> the</em><em> blood into </em><em>the</em><em> tube with heparin, it </em><em>must</em><em> be carefully </em><em>mixed</em><em> at least 8-10 times.</em>

<em>Test tubes with sodium heparin are used when it is necessary to determine the </em><em>level</em><em> of lithium in the patient's blood, which is relevant in psychiatric practice.</em>
