The titres obtained compare favourably with those obtained by densitometric methods. So far, the technique has not proved superior to the densitometric methods in either speed of operation or in reproducibility but various developments are suggested to effect this. %U https://jcp.bmj.com/content/jclinpath/19/6/589.full.pdf
