Quantitative measurement of serum and plasma lysozyme: an automated method

The demand for laboratory testing of blood lysozyme levels is increasing markedly. Although of limited value in the initial diagnosis of leukaemia, the importance of lysozyme levels in leukaemia management is rapidly being realised. An established manual method was examined in a successful attempt to develop an improved automated method using a centrifugal analyser. In comparison of serum and plasma the results showed no significant difference, indicating that the method described could use either material. The automated method was quicker, easier, more economical and more precise than the manual method it replaced.
