For usage, an equal volume of blood is gently, but thoroughly, mixed with the solution. This solution is used to study in vitro anti-inflammatory activity of crude drugs by the human red blood cell stabilization method.Gandhisan R, Thamaraichelvan A, Baburaj.

It is also used to preserve blood cells from other sources.{{cite journal | doi = 10.1111/j.1699-0463.1953.tb00242.x| title = Experiments on the Stability of Sheep Erythrocytes Stored in Alsever's Solution| journal = Acta Pathologica et Microbiologica Scandinavica| volume = 32| pages = 198–203| year = 2009| last1 = Schjerning-Thiesen| first1 = Knud| issue = 1| pmid = 13050415}}{{cite book| url= https://books.google.com/books?id=OLd91TkawxMC&pg=PA827 | page=827| title=L.S.A., List of C.F.R.
