As Galvani states, this issue returns every year.
CAP continues to send out the cells complement coated using a method that is KNOWN to cause cross reactivity with anti-IgG, particularly in CAT methods, hence their notification.
It seems that not all Cap subscribers outside USA get this notification, and are therefore in a difficult position: fail.
Interestingly, the CAP website states "for use with manual methods". What do they mean:not for CAT methods? Tube only? ...
I hope some CAP representatives are reading this blog, and will finally talk to the IH community and do something about this situation.
