Summary: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 four commercial laboratories in widely differing geographic areas, and using a somatic cell standard of 1.5 million per 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 four sets of data, only six discrepancies were observed between results based on decisions made by this and the standard fixed-sample-size procedure.
