Transfusion equipment for medical use - Part 4: Transfusion sets for single use, gravity feed (Attrezzatura di trasfusione per uso medico - Parte 4: Set di trasfusione monouso alimentati per gravità)

Assessment of damage to blood components
Transfusion sets shall be assessed against the range of blood components for which they are recommended to ensure that the relevant constituent(s) of each blood component is not significantly damaged (or where applicable, activated or inactivated) by passage through the set).

NOTE: For guidance on suitable tests:
— Red cell components:
Haemolysis – supernatant (free) haemoglobin and potassium (K+).
— Platelet concentrate:
Platelet damage – pH, swirling, hypotonic shock response (HSR), morphology index under phase microscopy, supernatant lactate dehydrogenase, P-selectin expression (CD62P) on platelet surface and supernatant, Beta thromboglobulin release.

P-selection expression è collegato anche a supernatant oltre che a "on platelet surface"? "...espressione P selectina sulla superficie delle piastrine e sul?? supernatante"??
