Editing Rheumatoid factor (section)

==History==
The test was first described by Norwegian Dr [[Erik Waaler]] in 1940 and redescribed by Dr [[Harry M. Rose]] and colleagues in 1948. Redescription is said to be due to the uncertainties due to World War II. It is still referred to as the Waaler–Rose test.<ref>{{cite journal |doi=10.1111/j.1699-0463.1940.tb01475.x |title=On the Occurrence of a Factor in Human Serum Activating the Specific Agglutination of Sheep Blood Corpuscles |year=2009 |last1=Waaler |first1=Erik |journal=Acta Pathologica et Microbiologica Scandinavica |volume=17 |issue=2 |pages=172–188}} reproduced in {{cite journal |doi=10.1111/j.1600-0463.2007.apm_682a.x |title=On the Occurrence of a Factor in Human Serum Activating the Specific Agglutintion of Sheep Blood Corpuscles |year=2007 |journal=APMIS |volume=115 |issue=5 |pages=422–38; discussion 439 |pmid=17504400 |last1=Waaler |first1=E|s2cid=221426678 }}</ref><ref>{{cite journal |pmid=18863659 |year=1948 |last1=Rose |first1=HM |last2=Ragan |first2=C |title=Differential agglutination of normal and sensitized sheep erythrocytes by sera of patients with rheumatoid arthritis |volume=68 |issue=1 |pages=1–6 |journal=Proceedings of the Society for Experimental Biology and Medicine |doi=10.3181/00379727-68-16375|s2cid=36340687 }}</ref>
