Romslo I. Lysozyme determined in serum or urine by a simple nephelometric method. Clin Chem 1977;23

We describe a nephelometric procedure for determination of lysozyme. A quantitative result is obtained in 2 to 3 mm with 50 tl of serum or urine. At a lysozyme concentration of 12.0 mg/liter, between-day precision was 3.4 % and the analytical recovery 96.5-105.5%. The values obtained were a linear function of enzyme concentration below 50 mg/liter, and they agreed with those obtained by absorp-tiometric determination of the decrease in turbidity of a suspension of Micrococcus lysodeikticus.
