Anti-Xa-Aktivität (Natrium-Heparinat)

Citrate plasma 1:10

LMW Heparin (low molecular-weight Heparin), unfractionated Heparin and the ‘new orally administered anticoagulants’ (NOACs, e.g. Fondaparinux, Rivaroxaban, etc.) have the effect of the preferred ‘Xa’ inhibitor factor because of their structure and molecular weight distribution. The dosage of such anticoagulants has to be adjusted to weight; laboratory checks are normally not necessary. Clinical indications for determining the ‘anti-factor Xa activity’ are: kidney insufficiency, pregnancy, long-term therapies, extreme bleeding- or thrombosis –hazard, or extreme over- or underweight, and in newborn babies and small children.
