ABSTRACT
The means and total components of variance were compared for the field and single strip direct microscopic somatic cell count (DMSCC) procedures. The field count procedure averaged 12 - 28% higher than the single strip count procedure in the 300,000 to 1,200,000 DMSCC/ml range. The sum of the components of variance in logarithm units for the field procedure was 0.01058 (1485 degrees of freedom) with a coefficient of variation of 24%, whereas the sum for the single strip procedure was 0.00834 (2834 degrees of freedom) with a coefficient of variation of 21%. This study demonstrates that the single strip procedure yields more reliable and less variable results than does the field procedure.
