Hello Jonathan

Yes, this was part of the reason for including TP but what really swayed it was work done by the immunologists in Cardiff on missing patients with hypogammaglobulinaemia if calculated globulin is not provided.
There's a cut off on the all Wales LIMS below which there's a message generated suggesting a check of immunoglobulins.

Best regards
Gethin

Morning Jonathan

Gethin is really the person to ask as he was directly involved at that time.

Thanks

Morning, Avril.

We took total protein out of all defined groups a few decades ago. Every so often I'd ask our haematologists if there was any value in earlier detection of paraproteins, and they always agreed there wasn't.

How did that discussion go in Wales? Or was there a different reason?

Thanks

Jonathan
