Somatic Cell Count Tester Performance Verification
Compare with FOSS & Bently flow cytometry analyzer
Introduction
SCCT tester based on fluorescence microscopy technolgy
FOSS or Bently tester based on Flow CytoMetry technology
If SCCT tester’s result maximum close to FOSS or BENTLY analyzer’s result, that mean SCCT Tester has good performance and it’s reliable device for somatic cell count of raw milk.
Verification method
Mainly verify two factors: Correlation & Repeatability
International standard: ISO13366 (IDF148) Milk-Enumeration of somatic cells
Results verification: Compare with FOSS or Bently flo cytometry analyzer
Correlation verify
SCCT vs Bentley SCC analyzer
SCCT vs FOSS SCC analyzer
FOSS vs Bentley
Repeatability Verify
200,000cells/ml raw milk samples
500,000cells/ml raw milk samples
Conclusion
Correlation: > 0.98 (compare with FOSS and Bentley)
Repeatability:
200,000cells/ml <7%
500,000cells/ml <5%
