Fluorescence Cell Counting vs Viscometric SCC Testing

Fluorescence-based cell counting and viscometric SCC testing use different measurement principles. When choosing an instrument, consider the intended use, supporting validation data, sample preparation, and total testing cost.

Fluorescence-based cell counting

SomaticScan uses stained milk samples, fluorescence microscopy, and automated image analysis to detect and count cells. The measurement provides a numerical somatic cell count for milk quality and udder-health monitoring.

Viscometric testing

Viscometric methods estimate SCC indirectly from changes in a milk sample after reaction with a reagent. Review the manufacturer’s instructions and validation information to understand the method’s range and suitability for your application.

Compare evidence for the complete instrument

A measurement principle alone does not prove that a particular device is certified, validated against an international standard, or suitable for regulatory reporting. Ask for model-specific comparison data, measurement range, repeatability, calibration or verification requirements, and applicable documentation.

Compare the cost per usable result

Consider instrument cost, consumables, operator time, maintenance, and additional testing where required. Select equipment for the decisions you need to make rather than assuming that price or method alone establishes performance.
