Point-of-care haematocrit vs a central laboratory haematology analyser

Public dataA public method-comparison deposit, not a laboratory's data. Systems are described generically; the source names them.

Central lab haematology analyser replaced by point of care haematology analyser: 201 paired results from a published study by Shean and Bennett (2026), re-analysed by NakedSignal as if the study were one laboratory. No decision limits are configured for haematocrit in %, so this comparison shows the comparison line and the average difference only.
