3x Coagulation tubes
Blood should be collected by clean venepuncture, using 19-21 gauge needles, into a 3ml citrate tube. Minimal stasis should be applied, with free flowing blood. Butterfly type needles may be convenient where multiple sample types are being collected. If blood must be collected through an indwelling cannula, this should be flushed with saline or balanced salt solution and the first 5-10ml blood discarded (try to avoid lines that have contained heparin).
Only available after prior discussion with a Consultant Haematologist.
If sanctioned, samples will be sent by same day courier to the referral centre.
Specimen tubes must be filled correctly.
