LimitationsHaemolysed samples give split alpha-2 peaks and should be avoided. Icteric samples show significant differences in appearance to normal serum and should not be analysed. Plasma samples should not be analysed as they contain fibrinogen which migrates in the beta-2 region, which could be interpreted as a paraprotein.

Incident at York Hospital

Please be aware that the internal access road to the Blue Badge car park at the front of York Hospital is temporarily closed following a road traffic incident. As a result, drop-off and collection at the main entrance, along with access to Blue Badge parking in that area, is currently unavailable. Pedestrian access is unaffected.

Access to all other areas of the hospital site remains open, including the multi-storey car park, where disabled parking is available.

We’re asking patients and visitors to plan ahead, as traffic flow into the site is busier than usual. Thank you for your patience and understanding.
