Abstract

A practical method is described to reduce the number of strips counted in the confirmatory Direct Microscopic Somatic Cell Count (DMSCC) procedure. Using data from 4 commercial laboratories in widely differing geographic areas, and using a somatic cell standard of 1.5 million/milliliter of milk, the method was found to allow count discontinuance after the first strip from 47.3% of the time (where it was least effective) to 92.2% of the time (where it was most effective). Of 675 observations in the 4 sets of data, only 6 discrepancies were observed between results based on decisions made by this and the standard fixed sample size procedure.
